RECEIVED I LA •RK 80+ Downflow WHAT TO DO IF YOU SMELL GAS: • Do not try to light any appliance. • Do not touch any electrical switch; do not use any phone in your building. • Immediately call your gas supplier from a neighbor's phone. Follow the gas supplier's instructions. • If you cannot reach your gas supplier, call the fire department These instructions are primarily intended to assist qualified individuals experienced in the proper installation of this appliance. Some local codes require licensed installation/service personnel for this type of equipment. Read all instructions carefully before starting the installation. Mooqs • Twinning The control board on these furnaces is capable of being twinned to another fumace of the same series. If using UTEC Control Boards, leave the fuses installed on each board. The thermostat wires and the 1/4 inch quick-connect terminals marked 'TWIN" on the furnace controls must - be wired for twinning. (See Figure 30.) Thermostat WGYR 0 0 0 0 • : : .........

Twinning 35 After Initial Power up: The control has a pro- grammed adaptive ignition feature which varies the wane -up period as follows: If ignition is successful the warm-up is reduced by 3- seconds on each subsequent call for heat until ignition failure occurs. Upon ignition failure, the warm -up is increased by 3- seconds on the next try. If successful, the timing remains fixed atthis level. In general, wheneverignition failure occurs the warm -up interval is increased by 3- seconds on the next try. And if successful, it remains there. Minimum and maximum warm - up time limits are set at 6 and 54- seconds, respectively. 7. The fumace control must prove flame via the flame sensor 5 seconds after the gas valve opens. If flame is sensed, all bumers are on and the ignitercools off. If no flame is sensed, the gas valve closes immediately and the inducer con- tinues to run. A second trial for ignition (step 6) begins if no flame is sensed on the fifth try for ignition, the f umace control is locked and the red LED will blink 4 times repetitively. The thermo- stat must be opened for at least ten seconds to reset the fumace control after a lock out. Otherwise, the fumace will attempt another ignition sequence in 1 hour. 8. The furnace control energizes the circulating air blower on the heating speed 30 seconds after the gas valve circuit is energized . 9. When the thermostat has been satisfied, gas valve is de- energized. 10. The inducer is de- energized after a 30- second postpurge. 11. The fumace control keeps the circulating air blower energized for 120 seconds (factory set) or 60, 90, or 180 seconds (field adjustable). (See Figure 27.) 12. Abnormal conditions: If a limit opens during operation, the inducer and circulating air blower continue to operate. The gas valve is de- energized immediately. The blowers continue to operate until the limit closes. When the limit closes the inducer blower is de- energized immediately. The circulating air blower contin- ues to operate for the specified delay (factory set at 120 seconds). Cooling Mode: 1. On a call for cooling the thermostat closes, applying 24 VAC to the G and Yterminals on the 34 '1N3W11000 3H130 JlllldtlO ail 013na SI 1133110N SIH1 NVH b1V313 S931 SI 3YNZI3 SIHl NI 1N3■f1a00 3H1 AI :33110N furnace control. This closes the compressor contactor. 2. The furnace control energizes the circulating blower (115 VAC) on the cooling speed. 3. When the thermostat is satisfied, the G and Y terminals on the control board are de- energized opening the compressor contactor. 4. The circulating air blower is de- energized after a 90- second delay. Fan Mode: 1. On a call for fan operation, the thermostat applies 24 VAC to the G terminal on the fumace control board. 2. The circulating air blower is energized immedi- ately on the heating speed. 3. If the furnace is operated in the continuous ON position at the thermostat and is then switched to AUTO, the circulating blower will operate for a specified delay (factory set at 120 seconds). Furnace Fails to Operate If the furnace does not operate check the following: 1. Is the thermostat operating properly? 2. Are the blower compartment door(s) in place? 3. Is the fumace disconnect closed? 4. Has the circuit breaker tripped or the control board fuse bumed open? 5. Is the gas tumed on? 6. Are any manual reset switches open? 7. Is the filter dirty or plugged? 8. Is the flame sensor coated? (Remove and clean with emery cloth.) If the fumace locks out after 5 attempts for ignition, it will try again every hour if a call for heat remains. If the inducer and circulating air blow- ers are operating, and items 1 through 8 have been checked, press the red reset button on the vent safety switch (See Figure 29). If the fur- nace operates after depressing the reset but- ton, contact a qualified serviceman to identify and repair the problem. If the furnace continues to not operate, depress the red reset buttons on the flame roll -out switches. (See Figure 29.) If the furnace oper- ates after depressing the reset buttons, contact a qualified servicemen to identify and repair the problem.

Avoid operating the fumace when windows and doors are open. 6. Be sure that the thermostat is properly installed and is not being affected by drafts or heat from lamps or other appliances. Sequence of Operation The operating sequences for the heating, cooling, and tan modes are described below. Refer to the field and furnace wiring diagrams; Figures 25, 26, 27 and 28. Heating Mode: 1. On a call for heat the thermostat closes, apply- ing 24 VAC to the W terminal on the control - board. 2. The control board checks for continuity on the 24 VAC limit control circuit (over - temperature limit switch, flame rollout switches and blocked vent switch in series). If an open limit is detected the control board will energize the inducer and the conditioned air blower. All other system functions will be inoperable until the limit circuit closes. While the limit is open, the red LED will pulse at a rate of 1 blink per unit time. 3. The fumace controlchecksforcontinuityacross the pressure switch (24 VAC). If the pressure switch is closed the heat mode sequence will not continue. If it remains closed for 10 seconds the red LED will blink 3times repetitively until the fault condition clears. Initial Power up: After 30 seconds of igniter warm -up the gas valve (24 VAC) will then open. The igniter circuit will stay energized for 3 seconds after the gas valve opens. 33 DOWNFLOW FURNACE MODELS FURNACE DIMENSIONS AND SHIPPING WEIGHTS Model Number •RK Furnace Input (Btuh) Dimensions Shipping Weights (Ibs) A inches B inches C inches 060(') -12 60,000 14 1/4 12 3/4 5 1/2 134 072(') -12 72.000 14 1/4 12 3/4 5 1/2 135 072(1-16 72,000 193/4 18 1/4 11 147 096(') -12 96,000 19 3/4 18 1/4 11 154 096(1-16 96,000 19 3/4 18 1/4 11 156 120(') -20 120,000 193/4 18 1/4 11 182 135(') -20 135,000 19 3/4 18 1/4 11 182 '1N3Wf130O 3H1 JO A1.IlVfO 3H101 91 1130110N SIHI NVH l=1V310 SS31 SI 3INVZIA SIHI NI 1N31 3H1 AI :30110N newly renovated homes may require more frequent changing until the construction dust has been removed. Filters for side return and bottom return appli- cations are available from your local distribu- tors. Lubrication The bearings in the circulating air blower motor and inducer blower used in these furnaces are pre - lubricated and sealed at the factory. No further oiling of the bearings is required for the life of the motor. Blower Compartment The blower compartment should be cleaned monthly during the heating and cooling seasons to remove any dirt and lint that may have accumulated in the compartment or on the blower and motor. Dirt and lint can create excessive loads on the motor resulting in higher than normal operating temperatures and short- ened service life. Heat Exchanger and Burner Maintenance The furnace should operate for many years without soot buildup in the flue passageways, however, the flue passageways, the vent sys- tem, and the burners should be inspected and cleaned (if required) by a qualified serviceman annually to ensure continued safe operation. Particular attention must be given to identify deterioration from corrosion or other sources. A\ WARNING: Holes in the vent pipe or heat exchanger can cause products of combustion to enter the home. Replace the vent pipe or heat exchanger if Teaks are found. Failure to prevent products of combustion from being circulated into the living space can create potentially hazardous conditions including carbon monoxide poisoning that could result in personal injury or death. 32 2. Turn off all power to the fumace and set the thermostat to the lowest temperature setting. 3. Remove the louvered door from the fumace. 4. Tum the gas control lever to the OFF position. 5. Disconnect the wires from the gas valve, igniter, flame sensor, combustion air motor, flame roll -out switch, blocked vent switch, over - temperature limit switch, pressure switch. 6. 8. Cleaning Of Flue Passages If the flue passages must be cleaned, follow the steps below. See Figure 29 for component 14. location and identification. 1. Shut off the gas supply to the furnace either at 15. the meter or at the manual valve in the gas supply piping. CAUTION: Label all wires prior to disconnection when servicing controls. Wiring errors can cause improper and dangerous op- eration. 7. 9. 10. 11. 12. 13. Remove the silicone rubber tube from the collector pan. For 'RA upflow models: Remove the screws that hold the vent control assembly to the top panel. Remove the nuts that hold the combustion air motor to the collector pan, and remove the complete combustion air blower and combus- tion tube assembly. BE CAREFUL NOT TO BREAKTHE SEALS AT EACH END OFTHE COMBUSTION AIR TUBE. Remove the screws that hold the collector pan in place, and remove the collector pan from the fumace. Using wrenches, separate the ground -joint union in the gas supply piping at the fumace. Remove the piping between the gas valve and the ground -joint union, if necessary. Remove the screws that hold the bumer as- sembly in place and remove the bumer assembly. BE EXTREMELY CAREFUL NOT TO DAMAGE THE IGNITER WHILE RE- MOVING THE BURNER ASSEMBLY. The fumace heat exchanger tubes can now be cleaned by the use of a round wire brush attached to length of high grade stainless steel cable, such as drain cleanout cable. Attach variable speed reversible drill to the other end of the spring cable. Slowly rotate the cable with the drill and insert it into the top portion of the heat exchanger. While reversing the drill, work the cable in and out several times to obtain sufficient cleaning. Repeat this sequence for each heat exchanger tube. When all heat exchanger tubes have been cleaned, any debris inside the tubes can be removed with the nozzle of a vacuum cleaner. With a light, check the condition of the uppe rand. lower sections of the heat exchanger tube.

The furnace is not to be used for temporary heating of buildings or structures under con- struction. INSTALLATION REQUIREMENTS Requirements and Codes This furnace must be installed in accordance with these instructions, all applicable local build- ing codes. current revision of the National Fuel Gas Code (ANSI - 2223.1), and in Canada with the CAN /CGA - B149 installation code. The current revision of the National Fuel Gas Code is available from: American National Standards Institute, Inc. 1430 Broadway New York, New York 10018 Additional helpful publications are: NFPA -90A - Installation of Air Conditioning and Ventilating Systems 8 NFPA -90B - Warm Air Heating and Air Conditioning Systems These publications are available from: National Fire Protection Association, Inc. Batterymarch Park Quincy, Massachusetts 02269 A\ WARNING: This furnace is not approved for installa- tion in mobile homes. Installation in a mobile home could cause fire, property damage, and/or personal injury. Location Upflow gas furnaces are shipped ready for installation in the upflow or horizontal right or left positions. The 'RK gas furnace is for downflow operation only. The furnace must be installed on a level surface, located as close to the vent (or chimney) and as close to the center of the air distribution system as possible. See Table 1 for overall dimensions to determine the required clearances in hallways, doorways, stairs, etc. to allow the fumace to be moved to the instal- lation point. The fumace must be installed so that all electrical components are protected from water. The furnace must be installed upstream from a refrigeration system. This furnace is not to be used for temporary heating of buildings or structures under construction. Clearances to Combustibles This furnace is Design Certified by CSA Inter- national for the minimum clearances to com- bustible material listed in Table 3. Refer to the furnace rating plate, located inside of the fur- nace cabinet, for the specific model number and clearance information. Access for positioning and servicing the unit must be considered when locating unit. 24 inches is the minimum required clearance from the front of the unit for servicing it. 30 inches is the minimum required clearance from the front of the unit for positioning it. 36 inches is the recommended clearance from the front of the unit. Please note that a panel or door can be located such that the minimum clearance on the rating plate is satisfied, but that panel or door must be removable and allow the appropriate clearance for your installation. This furnace is certified for use on wood floor- ing. This furnace must not be installed directly on carpeting, tile, or any combustible material other than wood flooring. Verifying Burner Operation To verify operation of the bumers, make sure that the furnace door is in place and that there is power to the fumace. Set the thermostat to a temperature above room temperature and observe the ignition sequence. The burner flame should carry over immediately between all burners. The flames should be blue, without yellow tips. Flames should extend from each burner without lifting off, curling, or floating. After verifying satisfactory flame characteristics, set the thermostat to a temperature below room temperature and verify that the bumer flame extinguishes completely. Verify Operation of the Supply Air Limit Switch To verify operation of the supply air limit switch, make sure that the blower door is in place and that there is power to the furnace. Block the return airflow to the furnace by installing a close - off plate in place of or upstream of the filter(s). Set the thermostat to a temperature above room temperature and verify that the Sequence of Operation is as described in these instruc- tions. The limit switch should function to turn off the gas valve within approximately four minutes (the exact time depending on the efficiency of the close -off in blocking the return air to the furnace). The circulating air and combustion blowers should continue to run when the limit switch opens. Remove the close -off immedi- ately after the limit switch opens. If the fumace operates for more than four minutes with no retum air, set the thermostat to a temperature below room temperature, shut off the power to the furnace, and replace the limit switch. DESCRIPTION OF COMPONENTS Figure 29 shows the location of each of the functional components described below. Also, refer to the Sequence of Operation Section of this manual . If any component of the furnace must be replaced, use only factory authorized replacement parts. See the Replacement Parts List for the factory authorized replacement for each component. Figure 27. Integrated Control Flame Sensor The flame sensor acts to prove that flame has carried over from the igniter to the opposite end burner. If no flame is sensed, the furnace will shut down within 7 seconds of ignition. Flame Roll -Out Switch The flame roll -out switch verifies that the bumer flames are drawn into the heat exchanger tubes. If the burner flames are not properly drawn into the heat exchanger, the flame roll- out switch will open. The circulating air blower (and combustion blower, if connected) will continue to operate if the flame roll -out switch opens.

Adjust all registers and duct dampers to the desired position and run the furnace for ten to fifteen minutes before taking any temperature read- ings. The temperature rise is the difference between the supply and return air tempera- tures. For typical duct systems, the tempera- ture rise will fall within the range specified on the rating plate with the blower speed at the factory recommended setting. If the temperature rise measured is outside the range specified, it may be necessary to change the blower speed. Lower blower speeds will increase the tem- perature rise and higher blower speeds will decrease the temperature rise. The furnace is equipped with a multi -speed motor. Heating and cooling speed selection is made by moving the leads on the integrated control located in the fumace. The wiring diagram on the furnace and Figure 28 show the speed taps for adjusting motor speed. If it is desired that the blower operate at the same speed for heating and cooling, tape off the Table 11. Gas Flow Rate unused blower lead and install the jumper wire found in the plastic instruction bag. Remove the desired blower tap, and install the jumper wire piggyback to the heating speed tap, and straight quick connect to the cooling speed tap. Recon- nect the desired blower tap to piggyback quick connect. The integrated control is factory set to start the circulating air blower 30 seconds after the gas valve is opened. The integrated control is factory wired to turn the blower motor off 120 seconds after the gas valve is closed. If necessary for comfort, the "off" time may be changed by adjusting the Blower Off jumper on the integrated control. See Figure 27 for blower on and off time adjustments.

If a switch reopens on start -up, DO NOT reset the switch without identifying and correcting the fault condition which caused the switch to trip. 5. The blower door is in place, closing the door switch in the line voltage circuit. 6. The gas line has been purged and all connec- tions are leak tight. Start-up Procedures After all of the above checks have been made: 1. Set the thermostat to the lowest setting. 2. Close the disconnect(s) to provide line voltage to the fumace. 3. Follow the procedures given on the operating instruction label attached to the fumace. 4. Set the thermostat above room temperature and verify the operating sequence. (See the Sequence of Operation). 5. After the fumace has run for approximately set the thermostat below room tem- perature and verify steps (9) through (11) of the Sequence of Operation. Verifying and Adjusting Firing Rate The firing rate must be verified for each installation to prevent over -firing the fumace. IMPORTANT NOTE: The firing rate must not exceed the rate shown on the furnace rating plate. At alti- tudes above 2000 feet it must not exceed that on the rating plate Tess 4% for each 1000 feet. Follow the procedure below to determine the firing rate. 1. 2. 3. 4. 5. 6. Adjustments to the firing rate can be made by adjusting the gas manifold pressure. See the High Altitude Application section for additional information of firing rate at elevations above 2000 ft. The manifold pressure must be set to the appropriate value for your installation. Refer to either Table 6 for natural gas or Table 7 for LP/ propane gas to verify the manifold pressure setting required for your particular installation. To adjust the manifold pressure, remove the regulator cap and turn the adjusting screw clockwise to increase pressure or counter- clockwise to reduce pressure. Replace the regulator cap after adjustments are complete. 0 CAUTION: Do not re -drill the burner orifices. If the orifice size must be changed, use only new orifices. Verifying and Adjusting Temperature Rise Verify the temperature rise through the furnace is within the range specified on the furnace rating plate. Temperature rises outside the specified range could result in premature heat exchanger failure. Place thermometers in the return and supply air stream as close to the furnace as possible. The NOTICE: IF THE DOCUMENT IN THIS FRAME IS LESS CLEAR THAN THIS NOTICE IT IS DUE TO THE QUALITY OF THE DOCUMENT. Shut off all other gas fired appliances. Start the fumace and allow it to run for at least three minutes. Measure the time (in seconds) required for the gas meter to complete one revolution. Convert the time per revolution to cubic feet of gas per hour using Table 11. Multiply the gas flow rate in cubic feet per hour by the heating value of the gas in Btu per cubic foot to obtain the firing rate in Btu per hour. Example: • Time for 1 revolution of a gas meter with a 1 cubic foot dial = 40 seconds. • From Table 11 read 90 cubic feet per hour of gas. • Heating value of the gas (obtained from gas supplier) = 1040 Btu per cubic foot. • Firing rate = 1040 x 90 = 93,600 Btuh. 27 .1N314111000 3H1 d0 AlllVilO 3H101 91 1130110N SIH1 NVH.J 9931 SI 31 SIHJ NI 1N3INf1000 3H1 AI :30110N The furnace cabinet must have an uninter- rupted, unbroken ground to minimize injury should an electrical fault condition occur. The controls used in this furnace require an earth ground to operate properly. Accept- able methods for grounding are electrical wire or conduit approved for electrical ground ser- vice. Do not use gas piping as an electrical ground. IMPORTANT NOTE: Proper line voltage polarity must be main- tained in order for the control system to operate correctly. Verify that the incoming neutral line is connected to the white wire and the incoming "hot" line is connected to the black wire. These furnaces will not operate unless the polarity and ground are properly connected. See Figure 25. Low Voltage Wiring Install the thermostat per the manufacturer's instructions. The low voltage (24 volt) connec- tions from the thermostat are made at the terminal strip on the integrated control in the 26 Figure 25. Line Voltage Field Wiring furnace. See Figure 26 for the proper connec- tions for heating only (two -wire) and heating/ cooling (four -wire) applications. The recom- mended minimum wire gauge for thermostat wiring is shown in Table 10. The thermostat must not be installed on an outside wall or any other location where its operation may be adversely affected. Adverse affects include radiant loading from fireplaces, sunlight, or lighting fixtures, and convective loading from warm air registers or electrical appliances. To determine the heat anticipator setting either. 1. Add the current draw of the system compo- nents; or 2. Measure the current flow on the thermostat R- W circuit after the circulating blower motor has started. Set the heat anticipator according to the ther- mostat manufacturer's instructions for heat anticipator settings.

However, the plenum attached to the coil casing must be installed such that its surface is at least 1" from combustible material in Figure 6. VENTING AND COMBUSTION AIR REQUIREMENTS General Provisions must be made in the installation of this furnace to provide an adequate supply of air for combustion. Detailed instructions for deter- mining the adequacy of an installation can be found in the current revision of the National Fuel Gas Code (ANSI Z223.1 / NFPA54) or in appli- cable local building codes. Consult local codes for special requirements. For Cana- dian installations consult Canadian Installations Codes and (CAN /CGA B149.1 or .2). If the furnace is operated with inadequate air for combustion one of the flame roll -out switches located in the bumer compartment or the vent switch will open, turning off the gas supply to the bumers. These safety devices are manually reset switches. DO NOT install jumper wires across these switches to defeat their function. DO NOT reset a switch without identifying and correcting the fault condition. If aswitch must be replaced, use only the correct part specified in the Replacement Parts List. Air openings in the fumace door, warm air registers, and return air grilles must not be restricted. Combustion Air Quality To maximize heat exchanger life, the combus- tion air must be free of chemicals which form corrosive acidic compounds in the combustion gases. The recommended source of combus- tion air is to use the outdoor air supply. How- ever, the use of indoor air in most applications is acceptable except as follows: 1. If the fumace is installed in a confined space it is recommended that the necessary combus- tion air come from the outdoors by way of attic, crawl space, air duct, or direct opening. 2. If outdoor combustion air is used, there must be no exposure to the installations or substances listed in Item 3 below. 3. The following types of installation may require Outdoor Air for combu ) due to chemical exposures: • Commercial buildings • Buildings with indoor pools • Fumaces installed in laundry rooms • Fumaces installed in hobby or craft rooms • Fumaces installed near chemical storage areas Exposure to the following substances in the combustion air supply may also require Out- door Air for combustion: • Permanent wave solutions • Chlorinated waxes and cleaners • Chlorine based swimming pool chemicals • Water softening chemicals • De -icing salts or chemicals • Carbon tetrachloride • Halogen type refrigerants • Cleaning solvents (such as perchloroethyl- ene) • Printing inks, paint removers, vamishes, etc. • Hydrochloric acid • Cements and glues • Antistatic fabric softeners for clothes dryers • Masonry acid washing materials A CAUTION: Combustion air must not be drawn from a corrosive atmosphere. A\ WARNING: Furnace installation using methods other than those described in the following sections must comply with the National Fuel Gas Code and all applicable local codes to provide sufficient combustion air for the furnace. Installation In An Unconfined Space An unconfined space is an area including all rooms not separated by doors with a volume greater than 50 cubic feet per 1,000 Btuh of the combined input rates of all appliances which draw combustion air from that space. For example, a space including a water heater rated at 45,000 Btuh input and a fumace rated at 75,000 Btuh requires a volume of 6,000 cubic feet [50 x (45 + 75) = 6,0001 to be considered unconfined. If the space has an 8 foot ceiling, the floor area of the space must be 750 square 11 Furnace Model Number 'RA, RK Furnace Input (Btu/hr) Cabinet Width (In.)

In general, a furnace installed in an unconfined space will not require outside air for combustion. However, in "tight" buildings (with weather stripping and caulk to reduce infiltration), it may be necessary to provide outside air to ensure adequate com- bustion and venting, even though the fumace is located in an unconfined space. Installation In A Confined Space A confined space is an area with volume less than 50 cubic feet per 1,000 Btuh of the com- bined input rates of all appliances drawing combustion air from that space. Fumace clos- ets, small equipment rooms and garages are confined spaces. Furnaces installed in a con- fined space which supply heated air to areas outside the space must draw return air from outside the space and must have the return air ducts tightly sealed to the fumace. A confined space must have two openings into the space for combustion air. One opening must be within 12 inches of the ceiling, and the other must be within 12 inches of the floor. The required sizing of these openings is determined by whether inside or outside air is used to support combustion, the method by which the air is brought to the space, and by the total input rate of all appliances in the space. Horizontal Furnace Installation The 'RA series fumaces can be installed hori- zontally in an attic, basement, crawl space or alcove. It can be suspended from a ceiling in a basement or utility room in either a right to left airflow or left to right airflow. (See Figures 7 and 8.) If the furnace is to be suspended from the ceiling, it will be necessary to use steel straps around each end of the furnace. These straps should be attached to the furnace with sheet metal screws and to the rafters with bolts. The fumace could also be suspended by an angle iron frame bolted to the rafters. (See Figure 7.) Access for positioning and servicing must be considered when locating the unit. Refer to Table 3, Minimum Clearances to Combustible Material, for clearance specifications. Keep all insulating materials away from the louvered door. Insulating materials may be combustible. 12 The 'RA series fumace may be installed di- rectly on combustible wood flooring or sup- ports, if type "B -1" vent pipe is used (See Figure 8). It is recommended for further reduction of fire hazard that cement board or sheet metal be placed between the furnace and the combus- tible floor and extend 12 inches beyond the front of the louvered door. WARNING: Furnaces installed with combustion air drawn from a heated space which in- cludes exhaust fans, fireplaces, or other devices that may produce a negative pressure should be considered con- fined space installations. 111161111NII11II11flI11IIII11IIVII Figure 7.

WARNING: To avoid electric shock, personal injury, or death, turn off the electric power at the disconnect or the main service panel before making any electrical connections. ELECTRICAL WIRING General Electrical connections must be made in accor- dance with all applicable local codes and ordi- nances, and with the current revision of the National Electric Code (ANSI /NFPA 70). For Canadian installations the electrical con- nections and grounding shall be done in accor- dance with the current Canadian Electrical Nate: (t) can be C o N. "rime -delay fuses or HACR -type circuit breakers are required. Table 10. Electrical Data Code (CSA C22.1, Part 1 an )ocal codes). If any of the original wire as b_,.plied with the fumace must be replaced, it must be replaced with wire having a temperature rating of at least 105 °C. Refer to the fumace nameplate and Table 10 for electrical requirements. Line Voltage Wiring The line voltage (115 volt) to the fumace must be supplied from a dedicated branch circuit containing the correct fuse or circuit breaker for the fumace. (See Table 10.) An electrical disconnect must be installed to be readily ac- cessible from and located within sight of the fumace. (See the Wiring Diagram label in the fumace and Figure 25.) A\ CAUTION: Label all wires prior to disconnection when servicing controls. Wiring errors can cause improper and dangerous op- eration. Verify proper operation after servicing.

Conversion Conversion of this fumace to use LP /propane gas must be made by qualified service person- nel, using only approved parts. A WARNING: This furnace was equipped at the factory for use with natural gas only. A special kit, supplied by the manufacturer, is re- quired to convert the furnace to operate on LP /propane gas. Failure to use the proper conversion kit can cause fire, ex- plosion, property damage, carbon mon- oxide poisoning, personal injury, or death. High Altitude Application High altitude application with this furnace can be field performed by a simple adjustment of mani- fold pressure, and if necessary changing the orifices. The changes required depend on the installation altitude and the heating value of the gas. The gas heating value based on sea level can be obtained from your local gas utility. The heating value of gas at high altitude is always lower than the sea level heating value. The heating values used in Tables 6 & 7 are based on sea level values. Natural Gas High Altitude Conversion All factory shipped furnaces are ready to oper- ate between zero and 4999 ft. above sea level. For higher altitudes (between 5000 and 10,000 ft. above sea level), conversion can be achieved simply by adjusting the furnace manifold pres- sure as shown in Table 6. LP /Propane Gas Sea Level and High Alti- tude Conversion IMPORTANT NOTE: When converting a low NOx furnace from Natural gas to LP/pro- pane gas, it is necessary to remove the NOx Baffles from the furnace. Conversion of this furnace to utilize LP /propane gas must be made by qualified service person- nel, using factory authorized or approved parts. Conversion to LP /propane gas can be accom- plished by first replacing the natural gas orifices with the appropriate LP /propane orifices shown in Table 8 or 9. Note: for installations between zero and 5000 ft. above sea level, a, #53, #54 or #55 drill size orifice should be used depend- ing upon the rated firing rate of the unit (see 23 Products of combustion must not be allowed to enter the return air ductwork or the circulating air supply. Failure to prevent products of combustion from being circulated into the living space can create potentially hazardous conditions including carbon monoxide poisoning that could result in personal injury or death. All return ductwork must be secured to the furnace with sheet metal screws. For installations in confined spaces, all return ductwork must be adequately sealed and joints must be taped. When return air is provided through the bottom of the furnace, the joint between the furnace and the return air plenum must be air tight. The floor or platform on which the fur- nace is mounted must provide sound physical support of the furnace with no gaps, cracks, or sagging between the furnace and the floor or platform. Return air and circulating air ductwork must not be connected to any other heat producing device such as a fireplace in- sert, stove, etc. Doing so may result in fire, explosion, carbon monoxide poisoning, personal injury, or property damage. 22 - Upflow Models- Left Side Entry Moe T - i 0 WARNING: . 1N3W11000 3Hi 30 A111dfO 3H1 01 3110 911130110N SIHJ NVH &NV310 9931 913WV IA SIHI NI iNaWn000 3H1 :30110N Downflow Models- Right Side Entry Ven ti Figure 24. Typical Gas Service Connection Wan Se Ile abore bee GAS SUPPLY AND PIPING General This furnace may be installed for either left or right side gas entry. A typical gas service hookup is shown in Figure 24. When making the gas connection provide clearance between the gas supply line and the entry hole in the furnace casing to avoid unwanted noise and /or damage to the furnace. All gas piping must be installed in compliance with local codes and utility regulations. Some local regulations require the installation of a manual main shut -off valve and ground joint union external to the furnace. The shut -off valve should be readily accessible for service and /or emergency use. Consult the local utility or gas supplier for additional requirements re- garding placement of the manual main gas shut- off. In the absence of local codes the gas line installation must comply with the latest edition of the National Fuel Gas Code (ANSI Z223.1) or (CAN /CGA B149.1 or .2) Installation Codes. An 1/8 inch NPT tap must be installed in the gas line to the unit for use when measuring the gas supply pressure. The tap should be readily accessible for service use. A drip leg should be installed in the vertical pipe run to the unit. Table 5 lists gas flow capacities for standard pipe sizes as a function of length in typical applica- tions based on nominal pressure drop in the line. IMPORTANT NOTES: 1. Gas piping must not be run in or through air ducts, chimneys, gas vents, elevator shafts, etc. 2. Compounds used on threaded joints of gas piping must be resistant to the actions of lique- fied petroleum gases. 3. The main manual gas valve and main power disconnect to the fumace must be properly labeled by the installer in case emergency shutdown is required. Leak Check After the gas piping to the furnace is complete, all connections must be tested for gas leaks. To check for leaks in gas piping systems, use only a soap and water solution or other approved method. the chimney. Single wall metal vents shall not be used for Category I venting, Category I fur- naces must be vented vertically or near verti -' cally. The furnace vent, if metal, may be insulated if local codes allow. Any part of the vent system, metal vent only, not exposed to weather, but which are exposed to ambient temperatures below 35° F must be insulated to prevent con- densation. All vent insulation shall be foil backed fiberglass of one inch minimum thickness. Three sheet metal fasteners (field supplied) should be used to secure the vent pipe to the furnace flue. These fasteners should be evenly spaced around the flue diameter, if possible. Category I - Common Venting When an existing furnace is removed from a venting system serving other appliances, the venting system is likely to be too large to properly vent the remaining appliances. An improperly sized venting system can result in the formation of condensate, leakage, spillage, etc. The steps outlined in the warning below shall be followed with each individual appliance con- nected to the vent system placed in operation, while all other appliances connected to the vent system are not in operation: A WARNING: CARBON MONOXIDE POISONING HAZARD Failure to follow the steps outlined below for each appliance connected to the venting system being placed into operation could result in carbon monoxide poisoning or death. The following steps shall be followed for each appliance connected to the venting system being placed into operation, while all other appliances connected to the venting system are not in operation: 1. Seal any unused openings in the venting system. 2. Inspect the venting system for proper size and horizontal pitch, as required in the National Fuel Gas Code, ANSI Z223. 1 /NFPA 54 or the CSA B149.1, Natural Gas and Propane Installation Codes and these instructions. Deter- mine that there is no blockage or restriction, leakage, corrosion and other deficiencies which could cause an unsafe condition. 3. As far as practical, close all building doors and windows and all doors between the space in which the appliance(s) connected to the venting system are located and other spaces of the building. 4. Close fireplace dampers. 5. Turn on clothes dryers and any appliance not connected to the venting system. Turn on any exhaust fans, such as range hoods and bathroom exhausts, so they are operating at maximum speed. Do not operate a summer exhaust fan. 6. Follow the lighting instructions. Place the appliance being inspected into operation. Adjust the thermostat so appliance is operating continuously. 7. Test for spillage from draft hood equipped appliances at the draft hood relief opening after 5 minutes of main burner operation. Use the flame of a match or candle. 8. If improper venting is observed during any of the above tests, the venting system must be corrected in accordance with the National Fuel Gas Code, ANSI Z223.1 /NFPA 54 and /or CSA B149.1, Natural Gas and Propane Installa- tion Codes. 9. After it has been determined that each appliance connected to the venting system properly vents when tested as outlined above, return doors, win- dows, exhaust fans, fireplace dampers and any other gas -fired burning appliance to their previous conditions of use. 15 The venting system should be designed to have the minimum number of elbows or tums. All horizontal runs shall be sloped upwards from the fumace at 1/4 inch per running foot of vent. Supports for the vent pipe must be installed a minimum of every five feet along the vent run to ensure no displacement after instal- lation. Under no circumstances shall any portion of the vent system extend into or pass through any return air duct, supply air duct, or plenum. If the furnace is operated with blocked or restricted venting, the blocked vent switch located in the vent plate will open, tuming off the gas supply to the burners. The blocked vent switch is a manually reset device. DO NOT install a jumper wire across this switch to defeat its function. DO NOT reset the switch without identifying and correcting the fault condition which caused the switch to trip. If this switch must be replaced, use only the part specified in the Replacement Parts List. 0 WARNING: Upon completion of the furnace installa- tion, carefully inspect the entire flue sys- tem both inside and outside the furnace to assure it is properly sealed. Leaks in the flue system can result in serious personal injury or death due to exposure of flue products, including carbon mon- oxide. Category III: Horizontal Venting NOTE: The reduced NOx models (eighth character N) are not approved as a Cat- egory III (Category III) furnace for use with horizontal venting. The furnaces are approved for use with 3" single wall AL29 -4C stainless steel vent pipe in horizontal vent applications. This pipe is available from the following manufac- turers: Z -FLEX Inc. - vent brand name (Z -VENT) Heat -fab Inc. - vent brand name (Saf -T Vent) Flex -L International - vent brand name (Star - 34 Vent) This vent pipe must be used for the entire length of the vent run. The installation must be in accordance with all instructions supplied by the 16 vent manufacturer for use on Category III appliances. When venting horizontal, this is defined as a Category III furnace, the vent pressure is positive, and the venting system must be sealed in both horizontal and vertical runs. For horizontal venting installations in both the United States and Canada the transition as- sembly must be modified by adding a bleed tube to the pressure switch tube and bypassing the vent switch. All model furnaces will require Vent Kit #903196 for horizontal venting. NOTE: No bleed tube is required for the 'RA 045(C,N) -08 model. Horizontal Venting For Upflow Models: 1. Remove the rubber tubing from the pressure switch sensor tube and the collector pan sen- sortube. Cut 1/2 inchf rom one end of the rubber sensor tube, fold in half and cut along the bend line. Discard the 1/2 inch long piece of tubing. Select the correct bleed tube using the table supplied with vent kit 41903196 and place the other two pieces of tubing on both ends of the bleed tube. Do not cover the hole in the bleed tube. Place the assembly back on the pressure switch sensor tube and the collector pan sen- sor tube. (See Figure 14.) 2. Remove the nut and restrictor plate from the vent collar assembly and discard the restrictor plate. Select the appropriate dilution cover plate as notedwithventkit #903196. Fittheclearance hole in the cover plate over the weld stud. The cover plate must cover the hole(s) on the vent collar assembly. Tighten the nut securely while holding the cover plate in position. (See Figure 15.) 3. Bypass the vent switch by removing both wires from the vent switch and attaching them to the wire nut. (See Figure 16.) 11 v.M CWW H.N - HN Figure 15. Vent Collar Detail Figure 16. Limit Circuit Wiring Flexible Vent Systems' Flexible gas vent is approved for use in vertical single vent or common vent installations only. The minimum distance to combustibles is 1 " for type B insulated and 6" for single wall. The venting system must be installed in accordance with the local authorities, the vent manufacturer's instructions and the instructions listed below. The flexible vent must be installed in accor- dance with the venting tables for vertical or common venting only. The vent system must be supported in horizontal runs with 3/4" pipe strap at a maximum of 5 foot intervals. All horizontal sections must have a slope toward the furnace of not less than 1/4" per foot. The vent must not sag, or have any bends greater than 90 degrees. CIRCULATING AIR SUPPLY General Plenums and air ducts must be installed in accordance with the Standard for the Installa- tion of Air Conditioning and Ventilating Systems (NFPA No. 90A) or the Standard for the Instal- lation of Warm Air Heating and Air Conditioning Systems (NFPA No. 90B). It is recommended that the outlet duct be pro- vided with a removable access panel. This opening should be accessible when the furnace is installed in service and shall be of a size that smoke or reflected light may be observed inside the casing to indicate the presence of leaks in the heat exchanger. The cover for the opening shall be attached in such a manner as to prevent leaks. If outside air is used as retum air to the furnace forventilation or to improve indoor air quality, the system must be designed so that the return air Figure 23. Typical Termination is not less than 50° F (10° C) uuring operation. If a combination of indoor and outdoor air is used, the ducts and damper system must be designed so that the retum air supply to the fumace is equal to the retum air supply under normal, indoor retum air applications. When a cooling system is installed which uses the fumace blower to provide airflow over the indoor coil, the coil must be installed down- stream (on the outlet side) of the furnace or in parallel with the fumace. Ifa cooling system is installed in parallel with the furnace, a damper must be installed to prevent chilled air from entering the fumace and con- densing on the heat exchanger. If a manually operated damper is installed, it must be de- signed so that operation of the fumace is pre- vented when the damper is in the cooling posi- tion and operation of the cooling system is prevented when the damper is in the heating position. Retum Air In applications where the supply ducts carry heated air to areas outside the space in which the furnace is installed, the retum air must be delivered to the fumace by duct(s) sealed to the furnace casing, running full size and without interruption. A WARNING: The solid base of the furnace must be in place when the furnace is installed with side return air ducts. Removal of all or part of the base could cause products of combustion to be circu- lated into the living space and create potentially hazardous conditions, in- cluding carbon monoxide poisoning that could result in personal injury or death. For upflow/horizontal installations: The retum air ductwork may be connected to any or all of the following: left side return, right side retum, or bottom retum. NOTE: Do not use the back of the furnace for retum air. Table 2 and 2a, in the front pages of these instructions, contains the airflow data for each fumace model. Where maximum airflow is 1800 CFM or more, two openings must be used for retum air.

(See Figure 21.) Vent termination clearances shall be con- sistent with the National Fuel Gas Code, ANSI 2223.1 /NFPA 54 and /or the CSA B149.1, Natural Gas and Propane Installation Code. All minimum clearances specified must be maintained to protect building materials from degradation by flue gases. 1. The termination tee must be 12 inches above snow level or grade level which ever is higher. See Figure 22 for alter- nate method to achieve 12" above snow level. 2. Avoid areas where condensate drainage may cause problems such as above planters, patios, or adjacent to windows where the steam from the flue gases may cause fogging. Do not terminate above any public walkway. 3. Select the point of wall penetration where the minimum 1/4 inch per foot of upward slope can be maintained. 4. When penetrating a noncombustible wall, the hole through the wall must be large enough to maintain the pitch, pipe clearance for passage, and provide for proper sealing. Penetrating a combus- tible wall requires the use of a wall thimble. (See Figure 22.) A 6 -1/2 inch square framed opening is required to insert the thimble halves. The thimble is adjustable to varying wall thickness and is held in place by applying sealant to the male sleeve before assembly. Also run a bead of sealant around the outer wall thimble. 5. The vent pipe must extend 1 -1/4 inches through the outer thimble half for a combustible wall. Be sure to check this carefully before cutting the vent pipe. 6. Attach a 3 inch coupling to the end of the pipe that extends through the wall or thimble. This prevents the vent pipe from being pushed inward. 7. Cut an 8 inch minimum piece of vent pipe and connect the coupling to the termination tee. The inside of the tee must be a minimum of 12 inches from the outside of the wall. (See Figure 23.) A Use Wall Thimble at Vent Points Support Termination Tee / / /// Ground Level / / /// Figure 22. Alternate Horizontal Vent Installation Horizontal Venting: "RK Models: 1. By -pass the vent switch, located on blower compartment door, by removing both wires from the switch. Remove wire terminals, strip wires and tie together in a wire nut. (See Figure 16.) 2. Remove the rubber tubing from the pressure switch sensor tube and the collector pan sen- ' 1 sor tube. Cut the tubing approximately 3" from one end. Select the appropriate dilution cover plate as noted with vent kit #903196. Insert the bleed tube into the tubing. Do not cover the hole in the bleed tube. Place the tubing assembly back on the pressure switch sensor tube and collector pan sensortube. (See Figure 17.) 3. To gain access to the restrictor plate, remove and discard the combustion tube from the transition assembly. Insure the seal between inducer and transition assembly is not broken. (See Figure 18.) 4. Remove and discard the restrictor plate and screw from the transition assembly. (See Fig- ure 18.) 5. Install and seal a 4" to 3" red uce rto the transition. (See Figure 19.) Attach the new high tempera- ture vent pipe to the reducer. 0 CAUTION: Do not drill holes through the vent pipe or fittings on a horizontal vented fur- nace. Do not use sheet metal screws, or rivets. Drilling, screws, or rivets will cause leaks. Figure 17. 'RK Bleed Tube Installation The components of the horizontal vent system must not be penetrated with screws, rivets, or other devices, either when joining pipes and fittings or using support straps. All joints must be sealed with high temperature silicone before locking bands are installed. If the lengths of pipe must be cut, the joint must still be sealed with silicone and the locking band used. When installing the condensate tube be sure to form a trap by means of a 3" loop filled with water. (See Figure 20.) Keep the number of pipe fittings to a minimum. Maintain a minimum of 6 inches of air space between the vent and combustibles at all times, this includes inside and outside the building. NOTE: The direction of the male - female joints from the drain tee to the termination tee is opposite to standard gas appliance venting. The male end of the pipes point towards the furnace.
