When you see this symbol on the furnace and in instructions or manuals, be alert to the potential for personal injury. Understand the signal words DANGER, WARNING, and CAU- TION. These words are used with the safety -alert symbol. DAN- GER identifies the most serious hazards which will result in severe personal injury or death. WARNING signifies a hazard which could result in personal injury or death. CAUTION is used to identify unsafe practices which would result in minor personal injury or product and property damage. These instructions cover minimum requirements and conform to existing national standards and safety codes. In some instances, these instructions exceed certain local codes and ordinances, especially those that may not have kept up with changing residen- tial construction practices. We require these instructions as a minimum for a safe installation. ELECTROSTATIC DISSCCH ARGER(EESD) PRECAUTIONS CAUTION: Electrostatic discharge can affect electronic components. Take precautions during furnace installation and servicing to protect the furnace electronic control. Precautions will prevent electrostatic discharges from personnel and hand tools which are held during the procedure. These precautions will help to avoid exposing the control to electrostatic discharge by putting the furnace the control. and the person at the same electro- static potential.

LOCATION A. General CAUTION: Do not install furnace in a corrosive or contaminated atmosphere. Make sure all combustion and circulating air requirements are met. CAUTION: Do not use this furnace during construction when adhesives, sealers, and/or new carpets are being installed and curing. If the furnace is required during construction, use clean outside air for combustion and ventilation. Compounds of chlorine and fluorine, when burned in combustion air, form acids which will cause corrosion of the heat exchangers and metal vent system. Some of these compounds are released from paneling and dry wall adhesives, paints, thinners, masonry cleaning materials, and many other solvents commonly used in the construction process. Excessive exposure to contaminated combustion air will result in safety and performance related problems. This furnace must be installed so the electrical components are protected from water. Locate furnace as near the center of the air distribution system and chimney or vent as possible. The furnace should be installed as level as possible. When a furnace is installed so that supply ducts carry air to areas outside the space containing the furnace, return air must also be handled by a duct(s) sealed to the furnace casing and terminating outside the space containing the furnace. Provide ample space for servicing and cleaning. Always comply with the minimum fire protection clearances shown on unit clearance label. This furnace shall not be installed directly on carpeting, tile, or any combustible material other than wood flooring. B. Location Relative to Cooling Equipment The cooling coil must be installed parallel with or on downstream side of furnace to avoid condensation in heat exchangers. When installed parallel with a furnace, dampers or other means used to control flow of air must prevent chilled air from entering furnace. If dampers are manually operated, they must be equipped with means to prevent operation of either unit unless damper is in full -heat or full -cool position. C. Hazardous Locations When furnace is installed in a residential garage, it must be installed so burners and ignition source are located at least 18 in. above the floor. The furnace should be protected from physical damage by vehicles. When a furnace is installed in public garages, airplane hangars, or other buildings having hazardous atmo- spheres, the unit must be installed in accordance with recom- mended good practice requirements of the National Fire Protection Association, Inc. II. AIR FOR COMBUSTION AND VENTILATION Provisions for adequate combustion and ventilation air must be provided in accordance with Section 5.3, Air for Combustion and Ventilation, of the NFGC or applicable provisions of the local building codes. Canadian installations must be in accordance with NSCNGPIC and all authorities having jurisdiction. —4— CAUTION: Air for combustion must not be contami- nated by halogen compounds, which include fluoride, chloride, bromide, and iodide. These elements are found in aerosol sprays, detergents, bleaches, cleaning solvents, salts, air fresheners, and other household products. All fuel- burning equipment must be supplied with air for combus- tion of fuel. Sufficient air MUST be provided to ensure there will not be a negative pressure in the equipment room or space. In addition, a positive seal MUST be made between furnace cabinet and return-air duct to prevent pulling air from burner area and draft safeguard opening into the circulating air. CAUTION: The operation of exhaust fans, kitchen ven- tilation fans, clothes dryers, or fireplaces could create a negative air pressure condition at the furnace. Make -up air must be provided for these devices, in addition to that required by the furnace. Combustion and ventilation air requirements are determined by whether the furnace is located in a CONFINED or UNCONFINED space. A. Unconfined Space An unconfined space has volume of at least 50 cu ft for each 1000 Btu it of total input for all appliances (such as furnaces, clothes dryers, water heaters, etc.) in the space. For Example: f the unconfined space is of unusually tight construction, air for combustion and ventilation MUST come from either the outdoors or spaces freely communicating with the outdoors. Combustion and ventilation openings must be sized the same as for a confined space as defined below. Return air must not be taken from the room unless an equal or greater amount of air is supplied to the room. --y B. Confined Space A confined space is defined as a space whose volume is less than 50 cu ft per 1000 Btu h of total input ratings of all appliances installed in that space. A confined space MUST have provisions for supplying air for combustion, ventilation, and dilution of flue gases using 1 of the following methods. (See Fig. 3 or 4 and Table 2.) NOTE: In determining free area of an opening, the blocking effect of louvers, grilles, and screens must be considered. If free area of louver or grille design is unknown, assume that wood louvers have a 20 percent free area and metal louvers or grilles have a 60 percent free area. Screens, when used, must not be smaller than 1 /4 -in. mesh. Louvers and grilles must be constructed so they cannot be closed, The size of the openings depends upon whether air comes from outside of the structure or an unconfined space inside the structure. 1. All air from inside the structure requires 2 openings (for structures not usually tight): a. Each opening MUST have at least 1 sq in. of free area per 1000 Btuh of total input for all equipment within the confined space, but not less than 100 sq in. per opening. (See Fig. 3 and Table 2.) The minimum dimension of air openings shall not be less than 3 in.

If furnace is installed on a raised platform to provide a return-air plenum, and return air is taken directly from hallway or space adjacent to furnace, all air for combus- tion must come from outdoors. 2. Air from outside the structure requires 1 of the following methods: a. If combustion air is taken from outdoors through 2 vertical ducts, the openings and ducts MUST have at least 1 sq in. of free area per 4000 Btuh of total input for all equipment within the confined space. (See Fig. 4 and Table 2.) b. If combustion air is taken from outdoors through 2 horizontal ducts, the openings and ducts MUST have at least 1 sq in. of free area per 2000 Btuh of total input for all equipment within the confined space.

START -UP, ADJUSTMENT, AND SAFETY CHECK A. General The furnace must have a 115 -v power supply properly connected and grounded. Correct polarity must be maintained to enable gas heating operation. The gas service pressure must not exceed 0.5 psig (14 -in. wc), and no less than 0.16 psig (4.5 -in. wc). Thermostat wire connections at R and W/W1 are the minimum required for gas heating operation. W2 must be connected for 2 -stage heating thermostats. Y/Y2 and G are required to be connected to the furnace for cooling and heat pumps. G is required for continuous -fan. CoM 24v is required for some clock thermo- stats. These connections must be made at the 24 -v terminal block on furnace control. (See Fig. 14.) 0 is required for heat pumps only. Y1 is required for 2 -stage cooling and 2 -stage heat pumps. The 0 and Y1 connectors must be made to the 1CM2+ furnace's orange and blue leads, flagged "O" and "Y1," respectively. This furnace can be installed with either a single -stage heating or a 2 -stage heating thermostat. For single -stage thermostats, connect thermostat R to W/W1 at the furnace control terminal block. (See Fig. 12.) For single -stage thermostats, the control will determine, based on length of previ- ous heating on and off cycles, when to operate in low- and high -stage for optimum comfort. Setup switch -2 (SW -2) must be in the factory - shipped OFF position. See Fig. 15 and Tables 6 and 7 for setup switch information. If a 2 -stage heating thermostat is to be used, move SW -2 to the ON position at end of furnace installation. This overrides built -in control process for selecting high- and low -stage and allows the 2 -stage thermostat to select gas heating modes. The W2 from thermostat must be connected to W2 on control terminal block. (See Fig. 13.) - -II- 4 3 BLOWER - OFF DELAY 2 1 LOW HEAT (ADAPTIVE ALGORITHM) HIGH HEAT ONLY OFF ON A96402 —> Fig. 15 —Setup Switches on Furnace Control Factory Settings) CAUTION: This furnace is equipped with a manual reset limit switch in the gas control area. The switch will open and shut off power to the gas valve if a flame rollout or overheating condition occurs in the gas control area. DO NOT bypass the switch. Correct inadequate combustion -air supply, component failure, or restricted flue gas passageway before resetting the switch. Before operating furnace, check each manual reset switch for continuity. If necessary, press and release the button to reset switch. B. Sequence of Operation Using schematic diagram in Fig. 16, follow the sequence of operation through the different modes. Read and follow diagram very carefully. NOTE: The GE ICM2+ BLWM speeds are infinitely variable from 300 to 1400 rpm and are dynamically controlled to precisely control airflow rate (CFM). The ICM2+ motor ramps to speed at a controlled rate to reduce start -up noise perception (4 to 11 sec, depending on the target CFM). The ICM2+ motor ramps down slowly to a stop in the same time as ramp -up time. ICM2+ ramp -up and ramp -down times are additive to blower -on and -off delays, respectively. The ICM2+ is 115 -v energized whenever power is available at furnace control, but operates only when 24 -v motor control input(s) are on, NOTE: If a power interruption occurs during a call for heat (W/WI or W/W1 and W2) and if the thermostat is still calling for gas heating, the control will start a 90 -sec blower only on period 2 sec after power is restored. The red LED will flash code 12 during the 90 -sec period, after which the LED will be on continuously as long as no faults are detected, The ICM2+ motor will operate at low -gas heat CFM after a power interruption in either low- or high -heat. After 90 -sec period, furnace will respond to the thermostat normally. The blower door must be installed for power to be conducted through blower door interlock switch (ILK) to furnace control (CPU), transformer (TRAN), inducer motor (IDM), blower motor (BLWM), hot surface ignitor (HSI), and gas valve (GV). I. Adaptive Heating Mode — Single -Stage Thermostat with 2 -Stage Heating (See Fig. 12 for thermostat connections.) NOTE: In response to thermostat call for heat R to W/W 1, control selects high -heat heating only with HIGH HEAT ONLY switch (SW I) set to ON regardless of LOW HEAT switch (SW2) setting.

NORMAL POSITION DESCRIPTION OF USE SW -1 Only High -Gas Heat OFF (Sta Gas Heat) Turn switch on to obtain only high - gas -heat operation on any call for heat regardless of whether R -W/W1, or R -W/W1, -W2 is closed, SW -1 overrides SW -2. SW-2 Low -Gas Heat (Adaptive Mode) OFF (Single-Stage Thermostat) Turn switch off for Installations with single -stage thermostats; con- trol selects low - gas -heat or high- gas -heat operation based on pre - vious cycles, Turn switch on for installations with 2 -stage thermo- stats to permit only low- gas -heat operation In response to closing R -W/Wi. High -gas heat is supplied only when R to W/Wi and W2 are closed. SW -3 and SW4 ON, OFF Switches control gas heating mode blower -off delay. (See Table 7.) �. TABLE 6 —SETUP SWITCH DESCRIPTION TABLE 7— BLOWER -OFF DELAY SETUP SWITCH (SW) POSITION With HIGH HEAT ONLY switch set to OFF, LOW HEAT switch selects either low -heat heating only mode when set to ON, or the adaptive heating mode when set to OFF in response to a thermostat call for heat R to W/W 1. (See Fig. 14 for description of switch settings or Fig. 16 for control circuit diagram.) This furnace can operate as a 2 -stage furnace with a single -stage thermostat because furnace control CPU in- cludes a programmed adaptive sequence of controlled operation, which selects low- or high -gas heat operation. This selection is based upon the stored history of the lengths of previous gas heating on/off periods of the single -stage thermostat. The furnace will start up in either low- or high -gas heat. If the furnace starts up in low -heat, the control CPU deter- mines low -heat on time (from 0 to 16 minutes) which is permitted before switching to high -heat. If power is interrupted, the stored history is erased. When this happens, the control CPU selects low -heat for 16 minutes and then switches to high -heat, as long as the thermostat continues to call for heat. Subsequent selection is based on stored history of thermostat cycle times. When thermostat calls for heat, R -W/W 1 circuit closes. The furnace control performs a self- check, verifies that the pressure switch contacts for low- and high -heat (LPS and HPS) are open, and starts motor IDM in low speed or high speed as appropriate. a. Inducer prepurge period —A 15 sec prepurge period begins when LPS contacts close. For high -heat opera- tion, both LPS and HPS must be closed. For low -heat operation, only LPS must be closed. b. Ignitor warm -up —At end of the prepurge period, the HSI is energized for a 17 -sec ignitor warm -up period. c. Trial- for - ignition sequence —When ignitor warm -up pe- riod is completed, the main gas valve relay contacts (MGVR -1 and -2) (and high -heat pressure switch relay HPSR for high -heat operation) close to energize low - and high -heat gas valve solenoid(s) (GV) and humidifier terminal (HUM). The gas valve opens, and 24 -v power is supplied for a field- installed humidifier at terminals HUM and CoM 24v. The GV permits gas flow to the burners where it is ignited. After 5 sec, the HSI is de- energized, and a 2 -sec flame- proving period begins. If the HPS fails to close on a call for high -gas heat and LP! closes, the furnace operates at low -heat gas flow rate unti HPS closes. d. Flame- proving —When burner flame is proved at flame proving sensor electrode (FSE), the control CPU begin the blower -on delay period and continues to hold G\ open. If burner flame is not proved within 2 sec, tht control CPU closes GV, and the control CPU repeats the ignition sequence for up to 3 more trials- for - ignitior before going to ignition lockout. The CONTROL TER- MINATES LOCKOUT AUTOMATICALLY after 3 hr, or by momentarily interrupting 115 -v power to furnace. or by interrupting 24 -v power at SEC1 or SEC2 to the control CPU (not at W/WI, G, R, etc.). Opening thermostat R -W circuit will not terminate an ignition: lockout. If flame is proved when flame should not be present, the control CPU locks out of gas heating mode and operates IDM on high speed until flame is no longer proved. e. Blower -on delay —If burner flame is proved, 45 sec after GV is opened BLWM is energized at the appropriate heating airflow: low- or high -heat CFM. Simultaneously, the EAC terminals are energized with 115v and remain energized as long as BLWM is energized. f. Switching from low- to high -gas heat —If furnace control CPU switches from low- to high -heat, control CPU switches the IDM speed from low to high. The high -heat pressure switch relay (HPSR) closes. When IDM pro- vides sufficient pressure to close HPS, the high -heat gas valve solenoid GV is energized. The BLWM switches to high -heat airflow 5 sec after the control CPU switches from low -gas heat to high -gas heat. g. Switching from high- to low -gas heat —The control CPU will not switch from high- to low -gas heat while the thermostat R -W circuit is closed when a single -stage thermostat is used. h. Blower -off delay —When the thermostat is satisfied, the R -W circuit is opened, the GV is de- energized, stopping gas flow to burners, and terminals HUM and CoM 24v are de- energized. The IDM remains energized for a 5 sec post -purge period. The BLWM, which had been operat- ing at low- or high -heat airflow, will operate at low -heat airflow for 90 sec. (1.) When in low -gas heat and thermostat is satisfied, blower will continue to operate at low -gas heat CFM until the blower -off delay reaches 90 sec. If blower -off delay switches (on the 2 -stage furnace control) are set for more than 90 sec, blower will operate at the selected continuous fan CFM for remaining blower -off delay time. 322293.101 REV.

When in high -gas heat and thermostat is satisfied, blower will continue to operate at high -gas heat CFM until the blower -off delay expires, for all settings of the gas heat blower -off delay switches on the 2 -stage furnace control. i. The furnace control is factory set for a 135 -sec blower - off delay. 2. Non - Adaptive Heating Mode— Two -Stage Thermostat and 2 -Stage Heating (See Fig. 13 for thermostat connections). NOTE: In response to thermostat call for heat R to W/W 1 and with HIGH HEAT ONLY switch SW1 set to OFF, the control selects low -heat only with LOW HEAT switch SW2 set to ON, or the control selects adaptive heating mode with LOW HEAT switch SW2 set to ON. The control selects high -heat only with HIGH - HEAT ONLY switch SW1 set to ON. In response to thermostat call for high -gas heat R to W1 and W2, the control selects high -heat regardless of switch SW1 and SW2 settings. See Fig. 14 for description of switch settings or Fig. 16 for control circuit diagram. The start-up and shutdown functions and delays described in item I apply to 2 -stage heating mode as well, except for switching from low- to high -gas heat and vice versa. a. When thermostat calls for heat, the R -W/W 1 circuit closes for low -gas heat or the R to WI-and-W2 circuits close for high -gas heat. The furnace control performs a self- check, verifies pressure switch contacts for low- and high -heat LPS and HPS are normally open, and starts IDM in low speed or high speed as appropriate. b. Switching from low- to high -gas heat —If the thermostat R -W/W 1 circuit for low -gas heat is closed and the R -W2 circuit for high -gas heat closes, the control CPU switches IDM speed from low to high. The HPSR closes. When IDM provides sufficient pressure to close HPS, high -heat gas valve solenoid GV is energized. The BLWM switches to high -stage airflow 5 sec after R -W2 circuit closes. c. Switching from high- to low -gas heat —If thermostat R -W2 circuit for high -stage opens and R -W/W 1 circuit for low -gas heat remains closed, the control CPU switches IDM speed from high to low. The HPSR opens to de- energize high -heat gas valve solenoid GV. When IDM reduces pressure sufficiently, HPS opens. The low -heat gas valve solenoid GV remains energized as long as LPS remains closed. The BLWM switches to low -heat airflow 5 sec after R -W2 circuit opens. 3. Cooling Mode a. Single -Speed Cooling Outdoor Unit (See Fig. 12 for thermostat connections.) (1.) The thermostat closes R to G -and -Y circuits. The R -Y circuit starts outdoor unit, and R to 0-and- Y/Y2 circuits start the furnace BLWM on cooling speed. (2.) The EAC terminals are energized with 115v when BLWM is operating. (3.) When thermostat is satisfied, the R to G -and -Y circuits are opened. The outdoor unit stops, and furnace BLWM continues operating at cooling air- flow for an additional 90 sec. b. Two -Speed Cooling Outdoor Unit (See Fig. 13 for thermostat connections.) (1.) The thermostat closes the R to G- and -Y1 circuits for low cooling or closes the R to G•and- Yl -and- Y/Y2 circuits for high cooling. The R to Y1 circuit operates the outdoor unit on low - cooling speed. The R to G- and -Y1 circuit operates the furnace BLWM at low - cooling airflow (65 percent of single -speed cooling airflow; different airflow than for low -gas heat). The R to Y1- and -Y2 circuits operate the outdoor unit on high - cooling airflow, and the R to G- and -Y/Y2- and -Y1 circuits operate furnace BLWM at high - cooling airflow. Two -speed high - cooling airflow is 105 percent of single -speed cooling airflow. NOTE: Y1 is found in the outdoor unit. The furnace control CPU controls BLWM airflow by sensing only G- and -Y l for low - cooling airflow and G- and -Y1- and -Y/Y2 for high - cooling airflow. (2.) Terminals EAC -1 and EAC -2 are energized with 115v when the BLWM is operating on either cooling airflow. (3.) When the thermostat is satisfied, the R to G -and- Y1 or R to G- and -Y1- and -Y/Y2 circuits open. The outdoor unit stops, the furnace blower continues operating on same cooling airflow for an additional 90 sec. 4. Continuous - Blower Mode a. When R to G circuit is closed by the thermostat, BLWM operates at LOW, MED, or HI (50 percent, 65 percent, or 100 percent of single -speed cooling airflow; different than low -gas heat airflow). LOW, MED, and HI selec- tions are described in Set -up Procedures. Terminals EAC -1 and EAC -2 are energized with 115v as long as the BLWM is operating. b. During a call for heat, the BLWM stops during ignitor warm-up (17 sec), ignition (7 sec), and blower -on delay (45 sec), allowing the furnace heat exchangers to heat up quickly, after which the BLWM operates at the appro- priate gas heating airflow. c. The BLWM reverts to continuous blower airflow after the heating cycle is completed. In high -gas heat, the furnace control CPU and 1CM2+ motor control hold the BLWM at low -heat airflow for a 90 -sec blower -off delay period (regardless of selected blower -off delay) before reverting to continuous - blower airflow. d. When thermostat "calls for low - cooling," the BLWM switches to low -cool airflow or the selected continuous - blower airflow, whichever is greater. Note that a HI selection for continuous - blower airflow will provide more than normal airflow during 2 -speed low- cooling. When the thermostat is satisfied, the BLWM switches to continuous - blower airflow. e. When the thermostat calls for high cooling, the BLWM operates at high -cool airflow. When the thermostat is satisfied, BLWM operates an additional 2 sec at high - cool airflow before reverting back to continuous - blower airflow. f. When R -G circuit is opened, BLWM continues operating for an additional 90 sec, if no other function require, BLWM operation. 5. Heat Pump Mode NOTE: A dual -fuel thermostat or accessory interface kit i. required with single -speed heat pumps. See dual -fuel thermostat o interface kit Installation Instructions for single -speed heat puml thermostat and interface connections. No interface kit is needed fo 2 -speed heat pumps. See 2 -speed heat pump Installation lnstruc tions to determine whether a standard or dual -fuel heat puml thermostat is required and for thermostat connections. a. Single -Speed Heat Pump Cooling (1.) The thermostat and interface kit close the R to Y/Y2- and -G -and -O circuits to operate the furnace BLWM at cooling airflow. The Y/Y2 input to the furnace control is necessary to provide adequate cooling airflow. (2.) Terminals EAC -1 and EAC -2 are energized with 115v when BLWM is operating. (3.) When thermostat is satisfied, furnace BLWM con- tinues operating at cooling airflow for an additional 90 sec. b. Two -Speed Heat Pump Cooling (1.) The thermostat R to G- and -Y1 -and -O circuits op- erate the furnace BLWM at low -cool airflow. The thermostat R to G- and -Y/Y2- and -Y1 -and -O cir- cuits operate the furnace BLWM at high -cool air- flow (105 percent of single -speed cooling airflow). NOTE: The furnace control CPU controls blower airflow by sensing G, Y1, and 0 for low -cool airflow and G, Y1, Y/Y2, and 0 for 2 -speed high -cool airflow. (2.) Terminals EAC -1 and EAC -2 are energized with 115v when the BLWM is operating at either cooling airflow. (3.) When the thermostat is satisfied, the furnace BLWM continues operating at the same cooling airflow for an additional 90 sec. c. Single -Speed Heat Pump Heating (1.) The thermostat and accessory interface kit R to 0- and-Y/Y2 circuits operate the furnace BLWM at heat pump heating airflow. Heating airflow is the same as cooling airflow for airflow selection HP- EFFY and 90 percent of cooling airflow for HP- CFMT selection. (2.) Terminals EAC -1 and EAC -2 are energized with 115v when the BLWM is operating. (3.) When thermostat is satisfied, the furnace BLWM continues operating at same heat pump heating airflow for an additional 90 sec. d. Two -Speed Heat Pump Heating (1.) The thermostat closes R to Y1 -and -G circuits for low heat and operates the furnace BLWM at heat pump low -heat airflow (may not be identical to low- cooling airflow, depending on HP selection at airflow selector). Closing R -Y/Y2, Y1 and G cir- cuits to furnace provides BLWM heat pump high - heat airflow. NOTE: The furnace control CPU controls BLWM airflow by sensing 0 and Yl for heat pump low -heat airflow, and G, YI, and Y/Y2 for heat pump high -heat airflow (105 percent of single -speed heating airflow). (2.) Terminals EAC -1 and EAC -2 are energized with 115v when BLWM is operating at either heating airflow. (3.) When the thermostat is satisfied, the furnace BLWM continues operating at same heating airflow for an additional 90 sec. (4.) Opening only R -Y/Y2 circuit switches BLWM to heat pump low -heat airflow. 6. Defrost a. When furnace control R to W/W1- and -Y/Y2 circuits are closed, furnace control CPU continues BLWM operation at heat pump heating airflow until the end of prcpurge period, then shuts off until the end of HSI ignitor -on period (22 sec). b. When installed with a heat pump, the furnace control CPU automatically holds the blower -off time to 22 sec during HSI ignitor -on period. After 17 sec of the HSI ignitor -on period, a trial -for- ignition sequence occurs as described above for gas heating. After flame is proven and without a blower -on delay, BLWM then operates at high- gas -heat airflow during defrost. For both single - speed and 2 -speed heat pumps, defrost mode is in high -gas heat only. c. When furnace control R -W/W 1 circuit is opened, the furnace control CPU begins the normal inducer post - purge period and the BLWM continues operating for the blower -off delay period. If the R -G circuit remains closed, the BLWM reverts to continuous- blower opera- tion. C. Set -up Procedures The ICM2+ blower motor operating mode selections are made on the airflow selector control with color -coded jumper wires. The factory jumper settings have large bold circles marked around the pins. (See Fig. 17.) NOTE: The ICM2+ furnaces are not approved for twinning. 1. Gas Heating a. The VIOLET wire is factory connected to 1 of 4 pins: A, B, C, or D on airflow selector. The factory pin selection can be checked by noting PIN marking in lower right - hand corner of furnace rating plate. b. The gas heating air temperature rise is selected on airflow selector (See Fig. 17.) with RED and VIOLET jumper wires. The selections are MID, HI, and MED -HI. MID gives mid point of temperature rise range marked on rating plate. HI gives high end of temperature rise range. MID -HI gives temperature rise about halfway between MID and HI. Select the rise by moving WHITE connectors on RED and VIOLET jumper wires to desired pin positions. These settings select the rise for high and low heat. See Table 8 for air temperature rise. 2. Cooling and Heat Pump Heating a. The cooling and heat pump selections can be determined from Tables 9 and 10. The selections are made by moving the WHITE connector on appropriately colored jumper wire to desired pin position. NOTE: Power must be cycled off and then on for the cool size selection to take effect. Power need not be cycled off and on for the CFM/TON to take effect. b. The YELLOW COOL SIZE jumper is used to select airflow to match the needed tons for the cooling or heat pump system. The BLUE CFM/TON jumper is used to select a slight adjustment to airflow. The traditional CFM per ton is 400 for cooling and heat pump airflow. 350 CFM per ton is the airflow used to attain best efficiency with these units. 315 CFM per ton is the airflow used for improved dehumidification and/or with undersized ducts. Additional humidity control can be attained by using a humidistat. (See Set -up Procedures section, item 4.) c. The ORANGE jumper wire selects airflow for cooling - only (AC) or heat pump heating and cooling, and selects heat pump heating best efficiency (HP EFFY) or en- hanced comfort (HP CMFT). HP EFFY provides the Dr -f �� ( - - ? _ -� b D 1 .111-1.

HP CMFT reduces the heating airflow to 90 percent of the cooling airflow for a higher air temperature rise and better comfort. 3. Continuous -fan The GREEN jumper wire selects airflow CFM for continuous -fan. LO provides 50 percent of airflow used for single -speed cooling or 2 -speed cooling. MED provides 65 percent of cooling airflow. HI provides 100 percent of cooling airflow for continuous -fan operation. NOTE: If HI is selected with a 2 -speed cooling or heat pump system, the airflow will remain at 100 percent of high - cooling/heating when the system is in low -cool and heat pump low -heat mode. Continuous -fan selection has no effect on gas - heating airflow. 4. As an alternative to selecting 315 CFM per ton for cooling airflow, an active dehumidification mode can be invoked by connecting a humidistat in series with the GREEN wire marked DEHUM connected to the 1 /4 -in. quick- connect terminal at G on furnace control. The humidistat contacts should open on a rise in humidity. When humidistat contacts open, airflow will be reduced to 80 percent of selected airflow, except that this airflow will not be reduced to less than 280 CFM per ton. NOTE: When a humidistat is calling for reduced airflow and the thermostat is satisfied, blower will not operate on continuous -fan LOW setting to prevent re- evaporation of condensate at the evaporator coil. When continuous -fan MED or HI setting is selected, normal airflow will be reduced to 80 percent. D. Start -up Procedures 1. Component test —The furnace features a component test system to help diagnose a system problem in the case of a component failure. To initiate the component test proce- dure, ensure that there are no thermostat inputs to the control and all time delays have expired. Short the TWIN/TEST terminal to ground or CoM 24v for 1 to 4 sec. (Sec Fig. 14.) NOTE: The component test feature will not operate if the control is receiving any thermostat signals or until all time delays have expired. The ICM2+ blower motor speed ramp -up will slightly delay blower response times. The component test sequence is as follows: a. The furnace control checks itself, operates the induce: motor on low speed for 7 sec and on high speed for 7 sec. then stops. b. The hot surface ignitor is energized for 15 sec, then de- energized. c. The blower motor operates at continuous -fan airflow fo: 7 sec then stops. d. The blower motor operates at high -gas heat airflow for i sec. The gas valve and humidifier terminal HUM are no . energized for safety reasons. e. The blower motor operates at single -speed cooling/hea: pump heating airflow (or 2 -speed heat pump high• heat/high- cooling) for 7 sec, then stops. NOTE: The EAC terminals are energized when the blower is energized. 2. After all connections have been made, purge gas lines an check for leaks. WARNING: Never purge a gas line into a combustion chamber. Never use matches, candles, flame, or other sources of ignition for the purpose of checking leakage. Use a soap- and -water solution to check for leakage. A failure to follow this warning can cause a fire, explosion, personal injury, or death. 3. To operate furnace, follow procedures on operating instruc [ions label attached to furnace. 4. With furnace operating, set thermostat below room tem perature and observe that furnace goes off. Set thermosta above room temperature and observe that furnace restarts E. Adjustments 1. Set gas input rate. Furnace gas input rate on rating plate is for installations a altitudes up to 2000 ft. In the U.S.A., input rating for altitudes above 2000 ft mu' be reduced by 4 percent for each 1000 ft above sea level. In Canada, input rating must be derated by 10 percent fo altitudes of 2000 ft to 4500 ft above sea level. Furnace input rate must be within ±2 percent of input 01 furnace rating plate. 2. Determine natural gas orifice size and manifold pressure fc correct input. a. Obtain yearly heat value average (at installed altitude from local gas supplier. b. Obtain yearly specific gravity average from local ga supplier. c. Verify furnace model. 'fable 11 can only be used fe model 333BAV and 333JAV Furnaces. d. Find installation altitude in Table 11. NOTE: For Canada altitudes of 2000 to 4500 ft, use U.S.A altitudes of 2001 to 3000 ft in Table 11. e. Find closest natural gas heat value and specific gravity i Table 11. f. Follow heat value and specific gravity lines to point I intersection to find orifice size and low- and high -he, manifold pressure settings for proper operation. ■ AC AIR CONDITIONING, COOLING AIRFLOW AC /HP JUMPER POSITION: HP —EFFY HEAT PUMP— EFFICIENCY, COOLING AND HEATING AIRFLOW HP —CFMT HEAT PUMP — COMFORT, COOLING AIRFLOW Furnace Size Airflow Selection Single -Speed CFM Two -Speed (High/Low) CFM Cool Size Jumper Position Tons Cool CFM Per Ton Jumper Position Cool CFM Per Ton Jumper Position 400 350 315 400 350 315 High Low High Low High Low 080 LO 1-1/2 600 530 500* 630 500' 550 500' 500' 500' M -LO 2 800 700 630 865 510 735 500' 660 500' M -Hl 2 -1/2 1000 880 790 1060 650 920 570 825 510 HI 3 1200 1050 945 1260 780 1100 680 990 585 080 LO 2-1/2 1000 875 790 1050 660 920 595 830 545 M -LO 3 1215 1050 945 1260 790 1100 700 990 625 M -HI 3 -1/2 1400 1225 1100 1470 910 1280 805 1155 715 HI 4 1600 1400 1350 1635 1040 1470 915 1325 820 100 LO 3 1195 1045 950 1260 780 1090 775 990 700' M -LO 3 -1/2 1400 1225 1090 1470 910 1285 830 1155 715 M -HI 4 1600 1400 1260 1680 1040 1465 915 1325 820 HI 5 2000 1750 1575 2085 1300 1840 1150 1655 1025 120 LO 3 1160 1050 955 1195 865 1085 785 985 785 M -LO 3 -1/2 1400 1220 1090 1420 970 1265 875 1150 845 M -HI 4 1600 1395 1250 1650 1070 1465 975 1315 930 HI 5 2000 1750 1565 2110 1300 1865 1140 1640 1080 FURNACE SIZE GAS HEAT TEMP RISE' GAS HEAT TEMP RISE ( °F)t GAS HEAT AIRFLOW (CFM) Jumpe Position High -Stage Low -Stage High -Stage Low -Stage Red Wire Violet Wire 060 HI A 51 45 925 615 M -HI A 46 38 1085 730 MID D 40 30 1250 1135 080 HI A 58 44 970 790 M -HI A 51 39 1140 925 MID D 45 29 1310 1395 100 HI A 51 44 1430 1035 M -HI A 45 39 1685 1215 MID D 40 30 1935 1630 120 HI A 69 49 1330 1240 M -Hl A 59 43 1560 1460 MID D 55 40 1720 1605 Use listed Jumper position combinations only. tWithin t 2 °F TABLE 8 —GAS HEAT AIRFLOW — NOMINAL CFM (WITH FILTER) TABLE 9 —AIR CONDITIONING AND HEAT PUMP COOLING/EFFICIENCY HEATING AIRFLOW NOMINAL CFM (WITH FILTER) • Minimum airflow is set for use with electronic air cleaner: 080 -500 CFM, 080 -500 CFM, 100 -700 CFM, 120 -700 CFM NOTES: 1.

This can result in unregulated manifold pressure and result in excess overtire and heat exchanger failures. BURNER ORIFICE A93059 CAUTION: DO NOT redrill orifices. Improper drilling (burrs, out -of -round holes, etc.) can cause excessive burner noise and misdirection of burner flames. This can result in flame impingement of burners and heat exchang- ers, causing failures. NOTE: If orifice hole appears damaged or it is suspected to have been redrilled, check orifice hole with a numbered drill bit of correct size. Never redrill an orifice. A burr -free and squarely aligned orifice hole is essential for proper flame characteristics. e. Move setup switch SW -2 to OFF position after complet- ing low -heat adjustment. f. Jumper R and W2 thermostat connections on control center. (See Fig. 14.) This keeps furnace locked in high -heat operation. g. Turn high -heat adjusting screw (5/64 hex Allen wrench) counterclockwise (out) to decrease input rate or clock- wise (in) to increase rate. NOTE: DO NOT set high -heat manifold pressure less than 3.2 -in. we or more than 3.8 -in. we for natural gas. If manifold pressure is outside this range, change main burner orifices. h. When correct input is obtained, replace caps that conceal gas valve regulator adjustment screws. Main burner flame should be clear blue, almost transparent. (See Fig. 19.) i. Remove jumper R to W2. 4. Verify natural gas input rate by clocking gas meter. a. Calculate high - altitude adjustment (if required).

Move the RED jumper wire on the airflow selector control to MID, HI, or M -HI for mid -point of the air temperature rise range, high end of the rise range, or in- between, respectively. The single RED jumper selection is used for both high- and low -heat rises, Power need not be reset after making this selection. CAUTION: Recheck the temperature rise. It must be within the limits specified on the unit rating plate. Recommended operation is at midpoint of rise range or above. 6. Set thermostat heat anticipator. a. When using a nonelectronic thermostat, the thermostat heat anticipation must be set to match the amp draw of the electrical components in the R -W/W 1 circuit. Accu- rate amp draw readings can be obtained at the wires normally connected to thermostat subbase terminals R ' and W/W 1. Fig. 20 illustrates an easy method(.. .ibtain- ing actual amp draw. The amp reading should be taken after blower motor has started and furnace is operating in low heat. To operate furnace in low heat, first move SW -2 to ON position, THEN connect ammeter wires as shown in Fig. 20. The thermostat anticipator should NOT be in this circuit while measuring current. If thermostat has no subbase, the thermostat MUST be disconnected from the R and W/W1 wires during the current measurement. Return SW -2 to final desired location after completing the reading. See the thermostat manufacturer's instructions for adjusting heat anticipator and for varying heating cycle length. b. When using an electronic thermostat, set cycle rate for 3 cycles per hr, if possible. Check Safety Controls flame sensor, gas valve, and pressure switches were all zked in the Start-up section as part of normal operation. 1. Check primary limit control. This control shuts off the combustion control system and energizes the circulating -air blower motor if the furnace overheats. The preferred method of checking the limit control is to gradually block off the return air after the furnace has been operating for a period of at least 5 minutes. As soon as limit has shut off burners, the return-air opening should be unblocked. By using this method to check the limit control, it can be established that the limit is functioning properly and will operate, if there is a motor failure. 2. Check draft safeguard switch. The purpose of this control is to cause safe shutdown of the furnace during certain blocked vent conditions. a. Disconnect power to furnace and remove vent connector from furnace flue collar. Be sure to allow time for vent connector pipe to cool down before removing. b. Restore power to furnace and set room thermostat above room temperature. c. After normal start -up, allow furnace to operate for 2 minutes, then block flue outlet 100 percent. Furnace should cycle off within 2 minutes. d. Remove blockage and reconnect vent connector to furnace flue collar. e. Wait 5 minutes and then reset draft safeguard switch. ;. Check flow - sensing pressure switches. This control proves operation of draft - inducer blower. a. Turn off 115 -v power to furnace. b. Remove gas control door and disconnect inducer motor leads from wire harness. —23— THERMOSTAT SUBBASE TERMINALS WITH THERMOSTAT REMOVED HOOK - AROUND VOLT /AMMETER 10 TURNS FROM UNIT 24 -VOLT TERMINAL BLOCK EXAMPLE: 6.0 AMPS ON AMMETER a 0.6 AMPS FOR THERMOSTAT SETTING 10 TURNS AROUND JAWS Fig. 20—Amp Draw Check With Ammeter A80201 c.

References made to the NSCNGPIC and ■mendment No. 1 apply to installations in Canada. Venting systems for Carrier fan - assisted furnaces shall be made in accordance with 1 of the bove codes and all authorities having jurisdiction. GENERAL INSTRUCTIONS 'hese instructions are for fan - assisted furnaces classified as Category I furnaces in accordance with ANSI Z21.47•CAN /CGA -2.3 -1993. ype -B connector and vent pipe, single -wall metal connector pipe, and/or lined masonry chimneys shall be used to vent Category I furnaces in ccordance with these venting instructions. Chimneys shall conform to the standard for chimneys, fireplaces, vents, and solid fuel burning ppliances ANSUNFPA 211 -1992 in the United States and to a Provincial or Territorial Building Code in Canada (in its absence, the National uilding Code of Canada Chimney Standard). . clay tile chimney liner in poor condition can be relined in lieu of repairing or rebuilding if the rest of the chimney is in good condition. If the :st of the chimney is in poor condition, repairing or rebuilding is required. UL listed (ULC listed in Canada) metal liner or a UL listed Type -B ent pipe shall be used for relining. Rebuilding and repairing shall conform to chimney standard. s chimney without a clay tile liner, which is otherwise in good condition, shall be rebuilt to conform to chimney standard or be lined with a UL sted (ULC listed in Canada) metal liner or UL listed Type -B vent. Relining with a listed metal liner or Type -B vent is considered to be a :nt -in -a- chase. a metal liner or Type -B vent is used to line a chimney, no appliance shall be vented into the annular space between the chimney and the metal •ter. lay tile -lined chimneys exposed to the outdoors below the roof line may require relining with a listed metal liner to reduce vent gas condensation cold climates. Experience in local areas with standard drafthood- equipped furnaces will indicate whether exposed tile -lined chimneys have mdensation problems. Fan- assisted furnaces installed in accordance with these instructions will not have chimney condensation problems if andard gas-fired drafthood - equipped furnaces installed in accordance with the NFGC or NSCNGPIC have not experienced condensation obletns in exposed tile -lined chimneys. CD 0 Co ( APPLIANCE APPLICATION REOUIREMEN.. Appliance operation has a significant impact on the performance of the venting system. If the appliances are sized, installed, adjusted, and operated properly, the venting system and/or the appliances should not suffer from condensation and corrosion. The venting system and all appliances shall be installed in accordance with applicable listings, standards, and codes. 1. The furnace should be sized to provide 100 percent of the design heating load requirement plus any margin that occurs because of furnace model size capacity increments. Heating load estimates can be made using approved methods available from Air Conditioning Contractors of America (Manual J), American Society of Heating, Refrigerating, and Air - Conditioning Engineers, or others. Excessive oversizing of the furnace could cause the furnace and/or vent to fail prematurely. 2. When a metal vent or metal liner is used, the vent must be in good condition and be installed in accordance with the vent manufacturer's instructions. 3. When a masonry chimney is used, chimney construction must conform to ANSI/NFPA 211 -1992 and must be in good condition. Inspections before the sale and at the time of installation will determine the acceptability of the chimney or the need for repair and/or (re)lining. An inspection chart is included on page 4. If the inspection of a previously used tile -lined chimney: a. Shows signs of vent gas condensation, the chimney should be relined in accordance with these venting tables with a listed metal liner or Type -B vent to reduce condensation. If a condensate drain is required by local code, refer to the NFGC, Section 7.9 for additional information on condensate drains. b. Indicates the chimney exceeds the maximum permissible size in these tables, the chimney should be rebuilt or relined to conform to these instructions. 4. The return-air temperature must be at least 60 °F db except for brief periods of time during warm -up from setback at no lower than 55 °F db or during initial start -up from a standby condition. 5. The furnace shall be adjusted according to the Installation, Start -Up, and Operating Instructions provided with the furnace for the following: a. Gas input rate — Insufficient gas input rate can cause low vent gas temperatures causing condensation and corrosion in the furnace and/or venting system. Derating is permitted only for altitudes above 2000 ft. b. Midpoint of the air temperature rise range —Low air temperature rise can cause low vent gas temperature. c. Thermostat heat anticipation or cycle rate to reduce short cycling. 6. Air for combustion must not be contaminated by halogen compounds which include chlorides, fluorides, bromides, and iodides. These compounds are found in many common home products such as detergent, paint, glue, aerosol spray, bleach, cleaning solvent, salt, and air freshener, and can cause corrosion of furnaces and vents. Avoid using such products in the combustion -air supply. Furnace use during construction of the building could cause the furnace to be exposed to halogen compounds, causing premature failure of the furnace or venting system due to corrosion. 7. Vent dampers on any appliance connected to the common vent can cause condensation and corrosion in the venting system. Do not use vent dampers on appliances common vented with this furnace. These venting tables apply only to appliances without vent dampers. —2— VERTICAL VENT OR CHIMNEY SIZING AND INSTALLATION 1. The Tables found on the following pages are based on the GAMA Venting Tables, the NFGC, and the NSCNGPIC. These tables are designed to be used with only Category I fan- assisted furnaces. The Tables provide a simple method to size typical vent and chimney installations without referring to the GAMA Venting Tables, the NFGC, and the NSCNGPIC. Additional venting and chimney configurations are possible by using the GAMA Venting Tables, the NFGC, or the NSCNGPIC. 2, Refer to the Installation Instructions titled VENTING TABLES CATEGORY I CENTRAL FURNACES, A.G.A., GAMA for full information concerning the requirements to use metal vents and masonry chimneys for these furnaces. The following information and warning must be considered in addition to the requirements defined in the GAMA Venting Tables Section III General Venting Requirements, the NFGC, and the NSCNGPIC. If a vent (common or dedicated) becomes blocked, the furnace will be shut off by the draft safeguard switch located on the inducer assembly. WARNING: Do not bypass the draft safeguard switch, as an unsafe condition could exist which must be corrected. Failure to follow this warning could result in a build -up of carbon monoxide and lead to personal injury or death. REMOVAL OF EXIT PING FURNACES FROM COMMON VENT SYSTEM 1. In replacement installations where an existing vent system may be used, inspect the vent system for condition, size, type of material, and height to meet the appliance application requirements. if it is oversized, condensation could corrode the venting system. Installation of a new venting system may be required. 2. When removing an existing furnace from a venting system serving other appliances, the vent system is likely to be too large to vent the remaining attached appliances properly. The following steps shall be followed with each appliance remaining connected to the common venting system placed in operation, while the other appliances remaining connected to the common venting system are not in operation. a. Seal any unused openings in the common venting system. b. Visually inspect the venting system for proper size and horizontal pitch and determine there is no blockage or restriction, leakage, corrosion, and other deficiencies which could cause an unsafe condition. c. Insofar as is practical, close all building doors and windows and all doors between space in which appliances remaining connected to the common venting are located and other spaces of the building. Turn on clothes dryers and any appliance not connected to the common venting system. Turn on any exhaust fans such as range hoods and bathroom exhausts, so they will operate at maximum speed. Do not operate a summer exhaust fan. Close fireplace dampers. d. Follow the lighting instructions. Place the appliance being inspected in operation. Adjust thermostat so appliance will operate continuously. e. Test for spillage at the drafthood relief opening after 5 minutes of main burner operation. Use the flame of a match or candle. f. After it has been determined that each appliance remaining connected to the common venting system properly vents when tested as outlined above, return doors, windows, exhaust fans, fireplace dampers, and any other gas - burning appliance to their previous conditions of use. g. If improper venting is observed during any of the above tests, the common venting system must be corrected. The vent system or vent connectors may need to be resized according to these instructions to approach the minimum size using the appropriate GAMA Venting Tables, Parts 7 and 11 in the United States or Part 7 of the NSCNGPIC and Amendment No. 1 in Canada, and all authorities having jurisdiction. For additional requirements refer to the National Fuel Gas Code NFPA 54- 1992/ANSI Z223.1 -1992 and ANSI /NFPA 211 -1992 Chimneys, Fireplaces, Vents, and Solid Fuel Burning Appliances in the U.S.A. or to the Canadian Installation Codes CAN /CGA- 8149.1 M91 and .2M91 and Amendment No. 1 in Canada.

An 88,000 Btu/hr 1- stage, fan - assisted furnace with a 4 -in. diameter flue collar is to be common vented with a 40,000 Btuh drafthood - equipped water heater with a 4 -in. diameter drafthood outlet. The common vent is an existing 25 -ft tall masonry chimney with 2 flues. The gas appliance flue is an 8- X 12 -in. nominal size clay -tile liner with a 3 -ft offset above the fireplace. The chimney flue is 6 ft from the water heater drafthood outlet. The furnace flue collar is 3 ft from the chimney flue. The headroom above the furnace and water heater is 5 ft and 3 ft, respectively. Including entrance into the chimney, 3 elbows will be required to route each connector to the chimney. CONNECTOR RISE: The water connector rise will be 2 ft to permit clearance to combustible construction. The furnace connector rise will be 3 ft to permit the furnace connector to enter the chimney below the water heater connector. (The water heater is 18 in. taller than the furnace.) FURNACE CONNECTOR: Try to size single -wall connectors with tile -lined masonry chimney from Table 8. When trying to enter the table at 25 ft Chimney Height, the table skips from 15 to 30 ft. See Table Application Requirement No. 2 on page 5. Try 15 ft Chimney Height with 3 ft Connector Rise, and try 30 ft Chimney Height with 3 ft Connector Rise. Move across the table to the Furnace Input column 84 -92 MBH and the Connector Horizontal Length column 0 to 6 ft. The connector sizes shown are NR and NR, which means that single -wall pipe is not recommended for this application. Try Type -B connector pipe. Enter Table 6 in the same way as Table 8. At 15 ft Chimney Height, 3 ft of Connector Rise, and at 30 ft Chimney Height, 3 ft of Connector Rise for 84 -92 MBH Furnace Input, and 0 to 6 ft of Connector Horizontal Length, Table 6 requires 4 -in. and 4 -in. Type -B connectors respectively. A 4 -in. Type -B connector should be used because the entries above and below the 25 ft Chimney Height are both 4 -in. connectors. ALTITUDE LIMITATION: The code letter J next to the connector size 4 indicates the maximum altitude. If the gas input rate is properly derated, the Altitude Code Letters Table at bottom of page 9 indicates the maximum altitude at which this furnace connector size shall be used (10,000 ft above sea level in this instance). MASONRY CHIMNEY: Continue down the same column to the Clay -Tile Chimney Liner Minimum and Maximum sizes, 8 X 8 and 12 X 12 in., respectively. The 8 X 12 -in. nominal liner fits within that range. Check the table titled Manifolded Connector and Offset Vent (or Chimney). See table on page 5 for L- Maximum Horizontal Length in the 8- X 12 -in. column. The 3 -ft offset is less than the maximum horizontal length, 13.5 ft. If the connectors are joined before they enter the chimney flue as shown in Fig. 5, L- Maximum Manifolded Horizontal Connector Length is 9 ft for a 6 -in. Type -B manifolded connector in the same table. Select the manifolded connector diameter, 6 in. from Table 6, Clay -Tile Chimney Liner Minimum and Maximum Circular Inside Diameter in the 84 -92 MBH column, which permits 6- to 10 -in. diameters. WATER HEATER CONNECTOR: Enter Table 9 at 30 ft Chimney Height, 2 ft of Connector Rise, 40 MBH Water Heater Input, 3 Elbows, and 0 to 6 ft Connector Horizontal Length. A 4 -in. diameter connector is required. Type -B and single -wall connector pipe are permitted. No altitude restrictions apply to vent connectors for drafthood- equipped water heaters or to common vents with a drafthood - equipped water heater. EXAMPLE 2: INTERPOLATION BETWEEN TABLE ENTRIES Use the same installation as in Example 1 except when furnace connector rise is 1 ft instead of 3 ft. Determine the furnace connection size. Enter Table 6. When trying to enter the table at 25 ft Chimney Height, the table skips from 15 to 30 ft. See Table Application Requirement No. 2 on page 5. Try 15 ft Chimney Height with 1 ft of Connector Rise, and try 30 ft Chimney Height with 1 ft of Connector Rise. Move across the table to the Furnace Input column 84 -92 MBH and the Connector Horizontal Length column 0 to 6 ft. The connector sizes shown are 5 in. and 4 in., respectively. A 5 -in. connector should be used because the Table Application Requirement No. 2.a. indicates to choose the larger of the connector sizes. The code letters H and J next to connector sizes 5 and 4 indicate the maximum altitudes. Use the altitude code letter H for the chosen connector size (in this instance, 5 in.).

These precautions will help to avoid exposing the control to electrostatic discharge by putting the furnace, the control, the motor, and the person at the same electrostatic potential. 1. Disconnect all power to the furnace. DO NOT TOUCH THE CONTROLS OR ANY WIRE CONNECTED TO THE CONTROLS PRIOR TO DISCHARGING YOUR BODY'S ELECTROSTATIC CHARGE TO GROUND. 2. Firmly touch a clean, unpainted, metal surface of the furnace chassis which is close to the controls. Tools held in a person's hand during grounding will be satisfactorily discharged. 3. After touching the chassis you may proceed to service the controls, motor, or connecting wires as long as you do nothing that recharges your body with static electricity (for example; DO NOT move or shuffle your feet, DO NOT touch ungrounded objects, etc.). 4. If you touch ungrounded objects (recharge your body with static electricity), firmly touch furnace again before touch- ing control or wires. 5. Use this procedure for installed and uninstalled (un- grounded) furnaces. 6. Before removing a new control or motor from its container, discharge your body's electrostatic charge to ground to protect the control or motor from damage. If the control or motor is to be installed in a furnace, follow items 1 through 5 before bringing the control, or motor, or yourself into contact with the furnace. Put all used AND new controls and motors into containers before touching ungrounded objects. 7. An ESD service kit (available from commercial sources) may also be used to prevent ESD damage, CARE AND MAINTENANCE For continuing high performance and to minimize possible equip- ment failure, it is essential that periodic maintenance be performed on this equipment. Consult your local dealer as to the proper frequency of maintenance and the availability of a maintenance contract. WARNING: Never store anything on, near, or in contact with the furnace, such as: 1. Spray or aerosol cans, rags, brooms, dust mops, vacuum cleaners, or other cleaning tools. 2. Soap powders, bleaches, waxes or other cleaning compounds, plastic or plastic containers, gasoline, kero- sene, cigarette lighter fluid, dry cleaning fluids, or other volatile fluids. 3. Paint thinners and other painting compounds, paper bags or other paper products. A failure to follow this warning could result in corrosion of the heat exchanger, fire, personal injury, or death. —2— • WARN Turn off the gas and electrical supplies to the unit before performing any maintenance or service on it. Follow the operating instructions on the label attached to the furnace. A failure to follow this warning could result in personal injury.

WARNING: Never use a match or other open flame to check for gas leaks. Use a soap - and -water solution. A failure to follow this warning could result in fire, personal injury, or death. D. Electrical Controls and Wiring NOTE: There may be more than 1 electrical supply to unit. The electrical ground and polarity for 115 -v wiring must be maintained properly. Refer to Fig. 7 and 8 for field wiring information and to Fig. 9 for unit wiring information. If the polarity is NOT correct, the furnace control will display rapid flashing on the status LED and prevent heat operation. The control system also requires an earth ground for proper operation of the microprocessor and variable -speed motor. NOTE: Be aware that measurement of current (amperes) and power (watts) for the ICM2+ variable -speed motor will be accurate only when the meter provides true root - mean - square (RMS) measurements. With power disconnected from unit, check all electrical connec- tions for tightness. Tighten all screws on electrical connections. If any smoky or burned connections are noticed, disassemble the connection, clean all parts and stripped wire, and reassemble properly and securely. Electrical controls are difficult to check without proper instrumentation; therefore, reconnect electrical power to unit and observe unit through 1 complete operating cycle. The 24 -v circuit contains an automotive -type, 3 -amp fuse located on the main control. Any 24 -v electrical shorts during installation, service, or maintenance could cause this fuse to blow. If fuse replacement is required, use ONLY a 3 -amp fuse. The control will display code 24 when the fuse needs replacement. {' The control in this furnace is equipped with an LED status light to aid in installation, servicing, and troubleshooting. It can be viewed through the sight glass or window on the blower access door. The control indicates status with the LED on continuously, rapid flashing, or a code composed of 2 digits. (The first digit is the number of short flashes, the second is the number of longs flashes.) Refer to the service label on the blower compartment door for code explanations and useful troubleshooting suggestions. (See Fig. 10.) It is important to note that power to the furnace must not be interrupted and the furnace blower door must not be removed until the LED status code(es) is recorded. When power to the control is interrupted, the status memory is erased. The control will store up to 5 previous codes but will not store non - current codes longer than 48 hr. To retrieve previous codes, if present, no thermostat inputs to the control must be present and all time delays must expire. Remove 1 of the red main limit wires 1 to 4 sec until the LED light goes out, then reconnect it. (See Fig. 4.) (Do not leave red wire disconnected for longer than 4 sec as the control will assume an overtemperature condition exits and will respond with indoor blower operation.) This places the control in the status recall mode and displays the first code stored in memory. Record the code and repeat the disconnect and reconnect of the red wire, recording each code until code 11 is displayed indicating no additional faults. After the last code is displayed or after 2 minutes in the code recall mode, the control will return to normal standby mode. Use any recorded status codes, the service label, and the trouble- shooting diagram on the following pages to diagnose and correct any problem condition. E. Troubleshooting Refer to the service label. (See Fig. 10.) Page 9 contains a troubleshooting guide. This guide can be a useful tool in isolating furnace operation problems. Beginning with the word "Start," answer each question and follow the appropriate arrow to the next item. The guide will help to identify the problem or failed component. After replacing any component, verify correct operation sequence. More information is available in a separate Troubleshooting Guide for 2 -stage gas -fired induced - combustion furnaces. 15 -V FIELD - SUPPLIED FUSED DISCONNECT 115 -V FIELD - SUPPLIED FUSED DISCONNECT FIVE WIRE THREE -WIRE HEATING - ONLY JUNCTION BOX CONTROL BOX FURNACE - Fig. 7—Heating and Cooling Application Wiring Diagram for Single -Stage Thermostats and/or Single -Speed Condensing Units AFS I: V TERMINAL BLOCK SEVEN WIRE FOUR -WIRE HEATING - ONLY JUNCTION BOX CONTROL BOX AFS • 24 -V FURNACE TERMINAL BLOCK NOTE 2 ,L — —1 'NOTE 1 Y1 NOTE 5 • lol NOTE 2 r Wt Y2 - - r, 1 i ii 1 NOTE 1 i _ 4 1 IY I NOTE 4 • IC] T r 1-STAGE THERMOSTAT TERMINALS 2 -STAG E THERMOSTAT TERMINALS CONDENSING UNIT • NOTE 4 - - -- FIELD 24 -V WIRING - - -- FIELD 115 -, 208/230 -, 460 -V WIRING FACTORY 24 -V WIRING FACTORY 115 -V WIRING FIELD - SUPPLIED FUSED DISCONNECT NOTES: 1.
