RECEIVED AUG 10 2010 PERMIT CENTER WARNING: Improper installation, adjustment, alteration, service, or maintenance can cause property damage, injury or death. Read the installation, operation, and maintenance instructions thoroughly before installing or servicing this equipment. WARNING: Gas -fired appliances are not designed for use in hazardous atmospheres containing flammable vapors or combustible dust, or atmospheres containing chlorinated or halogenated hydrocarbons. See Hazard Levels, page 2. WARNING: On makeup air heaters which also recirculate room air, outside ventilation air must be provided in accordance with the information shown on the heater nameplate. Recirculation of room air may be hazardo (a) Flammable solids, liquids, and gases; (b) Explosive materials; or (c) Substances which may become toxic w i• n ex General Description The information in this manual applies to Reznor® odel fired makeup air heating systems. The typical systel natural gas - fueled burner, and a draw - through blower o, cabinet. The system may be installed either indoors or outdoors. This direct -fired makeup air system provides tempered makeup air. Makeup air is defined as air that enters a building or arca due to negative pressure created by an air exhaust load in excess of the volume of entering air. This system warms the outside air and monitors the volume and temperature of the makeup air added to the building. The system may be used to provide ventila- tion in whole building or in spot applications. In whole building applications, adding controlled makeup air will cause less infiltration of dust and dirt; will eliminate continuous backdraft in chimneys and vents; and will reduce space heating fuel costs. tot I it MPLIANCE APPROVED 1 t �., I @� o Ali I 1 -RDF, P/N 148384 (Rev 1), Page 1 General Description (cont'd) Page 2 3Gall This system is available with various air control options to meet a wide range of application requirements. Depending on the air control option ordered, the supply air volume may be varied or the outside air may be supplemented with up to 75% building air (recirculation) for increased energy savings. These systems are designed - certified to ANSI Standards by the Canadian Stan- dards Association (CSA). (NOTE: Optional recirculation is available for U.S. installations only; recirculation is not available for Canadian installations.) In order to retain certification, the installer must adhere to the installation and operation requirements in the instruction manual. These direct -fired makeup air systems are not approved for residential use. 1. Installation Codes /Requirements Installation should be done by a qualified agency in accordance with the in- structions in this manual and in compliance with all codes and requirements of authorities having jurisdiction. The qualified agency installing this system is responsible for the installation. These units must be installed in accordance with local building codes. In the absence of local codes, the unit must be installed in accordance with the Na- tional Fuel Gas Code ANSI Z223.1a (latest edition) or CAN /CGA B149, In- stallation Codes for Gas Burning Appliances. These codes are available from CSA Information Services, 1- 800 - 463 -6727. Before installation, always consult authorities having local jurisdiction to verify that local codes and procedures are being followed. The building should always provide adequate relief for the heater to operate at its rated capacity. It should be noted that this can be accomplished by taking into account, through standard engineering methods, the structure's designed infiltration rate; by providing properly sized relief openings; by interlocking a powered exhaust system; or by a combination of these methods. Excessive recirculation or insufficient ventilation air which results in inadequate dilu- tion of the combustion products generated by the heater may create haz- ardous concentrations of carbon dioxide, carbon monoxide, nitrogen diox- ide, and other combustion products into the heated space. If the failure or malfunction of this heater creates a hazard to other fuel burn- ing equipment in the building, interlock the system to open inlet dampers or other such devices. Recirculation Requirements - Do not install a system with optional recircula- tion (building air) in the presence of flammable solids, liquids, or gases; explo- sive materials (i.e., grain dust, coal dust, gun powder, etc.); or substances which may become toxic when exposed to heat (i.e. refrigerants, aerosols, etc.). If a system with recirculation is being installed in an area where propane fork trucks or other fossil fuel powered equipment are used, the ventilation requirements for that equipment must be met. Recirculation is not recommended in uninsu- lated buildings where outside temperatures fall below 32 °F (0 °C). If in doubt regarding an application, consult the heater manufacturer's repre- sentative before installation. Codes for Special Installations: (1) Aircraft Hangar -- Installation in an air- craft hangar must be in accordance with the Standard for Aircraft Hangars, ANSI/NFPA 409 (latest edition) or CAN /CGA B149 Installation Codes; (2) Public Garage -- Installation in a public garage must be in accordance with the Standard for Parking Structures, ANSI/NFPA 88A (latest edition) or the Stan- dard for Repair Garages, ANSI /NFPA 88B (latest edition) or in Canada. with CAN /CGA B149 Installation Codes.

Rigging 8. Location and Mounting Weights Mounting on Field - Supplied Supports FIGURE 3 - Placement of Mounting Rails All cabinets are furnished with a curb cap and four lifting lugs for attaching rigging. To prevent damage to the cabinet, use spreader bars with the rigging chains. Mounting the system is the responsibility of the installer. Verify that the sup- porting structure has sufficient load - carrying capacity to support the weight. NOTE: Net weights are approximate for the standard system. Optional equip- ment is not included.

When selecting a location for an outdoor installation, position the unit so that the air inlet will NOT be facing into the prevailing wind. A minimum of 14" (356mm) clearance is required from the bottom of the air inlet hood to the mounting surface. Prior to installation, be sure that the method of support is in agreement with all local building codes. For both indoor and outdoor installations, check for ser- vice platform requirements. If an outdoor system is being installed with bot- tom discharge and/or return air, a full perimeter roof curb is recommended. The system is equipped with a load - bearing curb cap which forms an integral part of the unit. The curb cap provides required clearance from combustibles. Whether the system is being mounted directly on a surface or being placed "up" on additional structure, the horizontal length must be supported by two 4x4 treated wooden rails. Refer to FIGURE 3 for the appropriate lengths and spacing. When the system is placed on the rails, the curb cap "skirt" must fit over the edge of the boards with the rails setting inside the horizontal length of the curb cap. If the rails are laid directly on the mounting surface, position them as shown in FIGURE 3. Set the system on the rails leaving the "ends" underneath open for ventilation. If the wooden rails are not placed directly on a surface, cross - supports should be placed underneath the rails at the ends and at the cabinet "joint ". Refer to FIGURE 4. IMPORTANT NOTE: Mount an outdoor unit with a minimum of 14" clear- ance from the bottom of the inlet air hood to the mounting surface.

Be sure that the curb selected matches the unit ordered. Verify the dimensions of the curb received with the dimension table in FIGURE 5. Whether the roof curb is Option CJ3 designed for the system or a field -sup- plied curb, the roof curb dimensions in FIGURE 5 and the ductwork opening dimensions in FIGURE 7 apply. The roof curb designed for the system includes dividers that will create internal ductwork and duct connection flanges for ease of installation and so that the building ductwork can be attached before the system is set on the roof curb. FIGURE 5 - Dimensions of Optional Roof Curb (Option CJ3) - Shipped Separately IMPORTANT NOTE: Area enclosed by roof curb must comply with clearance to combustible materials. If the roof is constructed of combustible materials, area within the roof curb must be ventilated, left open, or covered with non- combus- tible material which has an "R" value of at least 5. If area within curb is left open, higher radiated sound levels may result. NOTE: Drawing is not proportional for all sizes. 1 -7/8 (48)_ 1 -7/8 (48) i 3 5 6, s. Q a „= L. ho y ��0 i.

If the system has a bottom discharge and/or a return air inlet, use the sheetmetal screws to sub - assemble the dividers. Refer to the dimensions in FIGURE 7 to appropriately position the roof curb dividers to create the needed duct opening flanges. Attach the dividers to the roof curb with sheetmetal screws. NOTE: If the system does not have a bottom discharge and/or a return air opening, the dividers for an opening that is not going to be used may be installed but are not required. 4. Check the assembly for squareness. The curb must be adjusted so that the diagonal measurements are equal within a tolerance of ± 1/8 ". 5. Level the roof curb. To ensure a good weatherproof seal between the unit curb cap and the roof curb, the roof curb must be leveled in both direc- tions with no twist end to end. Shim as required and secure curb to the roof deck before installing flashing. 6. Install field- supplied flashing. 7. Before placing the RDF unit on the curb, apply furnished 1/4" x 1 -1/4" foam sealant tape to the top perimeter surface of the curb, making good butt joints at corners. The sealant tape must be applied to the curb rails to prevent water leakage into the curb area due to blown rain and capillary action. Also place the foam sealant tape on the perimeter of the top surface of the duct opening(s), being sure to make good butt joints at corners. If install- ing ductwork from the top, it is recommended that tape be put on again after the ductwork is "dropped in ", sealing below and above the duct flanges. FIGURE 7 - Divider Locations for Bottom Ductwork Openings NOTES: • Drawing is not proportional for all sizes. • 3/4" (19mm) measurement is the width of the flanges where the roof curb mates with the heater.

Distribution of Makeup Air Makeup air can be introduced to the building either through distribution ducts or through controlled pressurization with little or no ductwork. Makeup air should be introduced and maintained using the lowest possible air velocity. With ductwork distribution, this is accomplished using a multiplicity of dis- charge openings over the greatest centerline distance. When a makeup air system is automatically controlled to maintain a set building pressure, the en- tering air will travel naturally toward the relief areas at the perimeter walls using the building structure as the distribution ductwork. Makeup air should enter at the highest point practical. By doing this, the fresh air will entrain dust laden air at the ceiling and move it toward the point of exhaust. Also, fresh air directed downward from the roof or ceiling will mix with hot ceiling air resulting in improved distribution of heat in the building. Form 1 -RDF, P/N 148384 (Rev 1), Page 9 9.

Proper sizing of warm air ductwork is necessary to ensure a satisfactory heat- ing installation. The recognized authority for such information is the Air Con- ditioning Contractors Association, 1228 17th Street, N.W., Washington, DC 20036. A manual covering duct sizing in detail may be purchased directly from them. ❑ The type of duct installation depends in part on the type of construction of the roof (wood joist, steelbar joist, steel truss, pre -cast concrete, etc.) and the ceiling (hung, flush, etc.). ❑ Rectangular ducts should be constructed of not lighter than No. 26 U.S. gauge galvanized iron or No. 24 B &S gauge aluminum. ❑ All duct sections 24" or wider, and over 48" in length, should be cross - broken on top and bottom and have seams or angle -iron braces. Joints should be S and drive strip or locked. ❑ Warm air ducts should not contact masonry walls. Insulate around all air ducts through masonry walls with not less than 1/2" of insulation. ❑ Insulate all exposed warm air ducts passing through an unheated space with at least 1/2" thickness of insulation. ❑ Duct Supports - Suspend all ducts securely from adjacent building members. Do not support ducts from unit duct connections. ❑ Duct Connections - At the heater, use a flexible canvas connection on indoor units to eliminate vibration transmission. On outdoor roof curb, down discharge connections, either drop an appro- priate sized and flanged duct into the roof curb prior to setting the unit or attach ductwork to the bottom flange (using curb dividers as ductwork). If dropping ductwork from the top, it is recommended that the top perimeter be sealed above and below the added ductwork. Do not use screws. See ductwork connection locations and sizing, pages 7 and 9. On outdoor horizontal installations, the ducts can be slid over the flange of the heater and then sealed for an airtight and watertight fit. On horizon- tal duct -to- heater connections and connections to the flanges at the bottom of the curb, use sheetmetal screws to fasten ducts to the heater flange. Use stiffening flanges around the perimeter of all duct connec- tions. ❑ Return Air Duct - The return air duct must be sized for a pressure drop of .5" w.c. at 2440 fpm in order to balance the system. If not sized properly, there may be difficulty in obtaining the desired airflow over the burner when the return air damper is full open. All electrical wiring and connections including electrical grounding must be in accordance with the National Electric Code ANSI/NFPA No. 70 (latest edition) or the Canadian Electrical Code Part 1- C.S.A. Standard C22.1. Check any local ordinances or utility company requirements that apply. Run a separate line voltage supply directly from the building electrical panel to the disconnect switch for the system. All external wiring must be within approved conduit and have a minimum temperature rise rating of 60 °C. For motor load amps, see Paragraph 12 or check the motor nameplate. System FLA is on the rating plate. Specific wiring diagrams and complete instructions are packed with each unit and should be kept readily accessible in legible condition. A safety disconnect is required. Refer to FIGURE 8 for recommended loca- tion and install the disconnect switch in accordance with Article 430 of the National Electrical Code ANSI/NFPA 70 or in accordance with Canadian Elec- CAUTION: If any of the original wire must be replaced, the replace- ment wire must have a temperature rating of at least 105 °C except for controls mounted in the discharge airstream which must be 150 °C. See Hazard Levels, page 2.

The "teeth" should face the disconnect switch, scratching off the painted surface. Attach the disconnect tightly against the heater cabinet. Run cable so that it does not interfere with cabinet panels or doors. When providing or replacing fuses in a fusible disconnect switch, use dual element time delay fuses and size according to 1.25 times the maximum total input amps. Convenience Outlet Option When a convenience outlet option is included, an individual power supply must be provided to the receptacle. This circuit MUST BE on a ground fault breaker to meet requirements. All wiring to the convenience outlet must meet National Electrical Code ANSI/NFPA No. 70 (latest edition) or the Canadian Electrical Code Part 1- C.S.A. Standard C22.1. and any local or utility codes that may apply. A 7/8" diameter opening suitable for watertight conduit connection is pro- vided as the entrance of 24 -volt control wiring to the electrical compartment. For location, see FIGURE 8. Low voltage wiring must be in individual con- duit, separated from primary high voltage wiring. CAUTION: Supply voltage and 24 -volt control wiring cannot be installed in the same conduit. Maxitrol systems will be adversely affected if control wiring is in conduit with supply voltage wiring. If required, field - supplied wiring between any Maxitrol components must be completed with shielded wiring. A 3- position control switch mounted in a 4x4 box is supplied with each system (exception - not included with systems with Option AG37 designed for com- puter control), either packed loose inside the unit, or if an optional control console (Option RC l3 or RC14; See FIGURE 9) is ordered, the switch is mounted on the console. Control wiring requirements depend on the options selected. Follow the cus- tom wiring diagram supplied with the system to connect any remote controls. In this paragraph, there is a brief description of the optional electrical controls used for airflow. Refer to the operation manual, Form O -DV /RDF /ADF, for additional control information.

(Cabi- net installation instructions are in Paragraph 15.) 1) Run the tubes through the holes in the cabinet wall. Pull gently to extend the tubing to its entire length without stress. 2) Position the tubing approximately at the center of the height of the filter rack. 3) Identify the tube connected to the positive connection on the switch (FIGURE 11) as the positive pressure tube. Determine the length of tubing required to attach the positive pressure tube so that it will sense pressure at the inlet side of the filter rack. Identify the tube connected to the negative connection on the switch (FIG- URE 11) as the negative pressure tube. Determine the length of tubing required to attach the negative pressure tube so that it will sense the pressure at the blower side of the filter rack. (NOTE: Tubing shipped is the same length for all sizes of systems; cut to the appropriate length for the smaller systems.)

Using the clamps provided, attach the ends of the tubing to the filter rack at about center height being careful not to kink or compress the tubing. ❑ After the system is operating, the filter switch must be manually set. With clean filters in place, blower doors closed, and blower in operation, increase the pressure setting by adjusting the set screw on the switch FIGURE 12 - Discharge Sensor and Mixing Tube FIGURE 13 - Control used for Outside Air Cutoff and Discharge Temperature Low Limit (Freezestat) FIGURE 14 - Optional Door Switch clockwise until the filter light is energized or the screw is bottomed out. At that point, adjust the set screw three full turns counterclockwise or until the screw is top ended. At that setpoint, the filter light will be activated at approximately 50% filter blockage. Discharge Sensor (Maxitrol) for Gas Control Options AG30, AG31, AG32, AG33, AG47, AG48 A discharge sensor may be shipped separately for field installation. Attach the discharge sensor and mixing tube in the ductwork about six feet (1.8 M) from the discharge opening of the system. The sensor housing is not waterproof. If the installation is outdoors, field -fab- ricate a waterproof protective enclosure for the discharge sensor, being careful not to affect its air temperature sensing capability. If the ductwork is insulated, be sure that the sensing bulb is mounted so that it is fully exposed to the air- stream being sensed. Refer to the wiring diagram and connect the sensor to the terminal strip in the blower section electrical box. Use shielded wire to alleviate any electrical in- terference that may cause an erroneous discharge temperature reading. Outside Air Cutoff Control (Option BN2) After sensing pilot flame, the burner ignites at its lowest input rate. The "amount of heat" required to reach the desired discharge temperature also depends on the temperature of the incoming outside air. The outside air cutoff (high ambi- ent control) is factory set at 60 °F (adjustable 25- 250 °F). The burner reacts differently depending on the entering air temperature and the setting on this control. The burner -- • may not ignite (pilot valve will not open); If the actual temperature of the outside air is above the setpoint on the outside air control, the burner will not ignite. • may modulate to satisfy discharge setting; • would shutdown completely only on Option BN2 control, once burner has been fired; or Modulating operation will depend on the temperature rise between the outside air and the discharge air setting. • may remain on continuous low fire. If the outside air control is set too high, the burner will continuously burn on low fire as long as the control switch is set to "winter ". When the outside air control is set properly for the climate, the system blower will continue to provide the required makeup air (ventilation) at the ambient outdoor temperature (burner not operating) even when the control switch is set to "winter ". If at startup, it is determined that the outside air cutoff control is not set prop- erly, change the setting on the control (located in the main electrical compart- ment) and test for proper operation. Discharge Temperature Low Limit (Option BE2) If the system has an optional low limit switch for discharge temperature (freezestat), the control is in the blower section electrical box. The sensing bulb must be field- mounted in the blower discharge duct connector. Uncoil the control and extend the bulb to the blower discharge, being careful to not inter- fere with any mechanical parts. Use the bulb holder provided and mount the sensor according to the manufacturer's instructions. Door Switch (Option BX1) If the system is to be used as an overhead door heater, an optional door switch (Option BX l) must be installed. The function of the switch is to energize and Form I -RDF, P/N 148384 (Rev 1), Page 13 10. Electrical Controls (cont'd) FIGURE 16 - Optional Potentiometer Installation Instructions for Pressure Null Switch (See FIGURE 18): Page 14 Door Switch (cont'd) interlock the system when an outside overhead door reaches approximately 80% of full open travel. The switch will de- energize the system when the over- head door closes approximately 20 %. Follow the installation instructions in the door switch option package and the wiring diagram. Firestat (Option BD5) If the system has an optional firestat, the control is factory installed in the heated airstream so that the sensor extends into the duct. This control requires manual reset so is installed in an accessible location. Optional Potentiometer (applies to systems with Air Control Option AR19 for makeup air only or AR22 for outside and recirculation air) If the system includes Air Control Option AR19, the discharge damper is con- trolled by a manually set potentiometer. If the system includes Air Control Option AR22, the potentiometer controls the return air damper. The potenti- ometer is shipped loose in the control compartment, or if a remote console is ordered, it is mounted on the console. Follow the wiring diagram to connect the potentiometer. Optional Pressure Null Switch (applies to systems with Air Control Option AR20 for makeup air only or AR23 for outside and recirculation air) If the system includes Air Control Option AR20, the discharge damper is con- trolled by a pressure null switch. If the system includes Air Control Option AR23, the pressure null switch controls the return air damper. The pressure null switch is shipped in the control cabinet. Refer to the following paragraphs and to the manufacturer's installation instructions to install and connect this switch. The pressure null switch is Dwyer #1460 -0 with a range of .01 -.12" w.c. The pressure null switch is a diaphragm operated differential pressure switch used in makeup air applications to control building pressure. It maintains a selected positive or negative pressure setpoint by changing the amount of outside air being introduced to the building through the modulating outside air dampers. As more pressure is required in the building, the pressure null switch activates the damper motor driving the outside air damper towards the full open posi- tion and the recirculated air damper towards the closed position. Conversely, as less pressure is required, the switch drives the dampers in the opposite di- rection. Select an indoor location free from excessive vibration where oil or water will not drip on the switch and where ambient temperature will be within a range of -30 °F (dry air) to 110 °F. Mount the switch with the diaphragm in a vertical plane. The switch is position sensitive and is calibrated to operate properly when the diaphragm is vertical. Mount switch securely. Connect the pressure taps on the top of the switch to sources of air pressure differential. Metal tubing with 1/4" O.D. is recommended but any tubing which will not unduly restrict the airflow can be used. To maintain a positive building pressure, vent the low pressure tap to the outdoors and allow the high pressure tap to monitor building pressure. To maintain a negative building pressure, reverse the functions of the high and low pressure taps. In either case, be sure that the outdoor vent is protected from the wind and screened from insects. FIGURE 18 - Pressure Null Switch included in Air Control Options AR20 and AR23 Adjustment of the Switch - The "high" actuation point of the null switch is indicated on a calibrated scale secured to the transparent range screw enclo- sure. Building pressure is set by turning the adjustment screw. The "low" ac- tuation point is set by adjusting the span on the null by turning the span adjust- ment screw. The span range is .01 to .03" w.c. IMPORTANT: To eliminate shipping damage to the switch contacts, the manufacturer reduced the span adjustment to zero before shipping. The span should be adjusted prior to using the switch. (If the switch has been installed, disconnect the vent tube so that the null switch is in a neutral position.) Remove the switch electrical box cover and while observing the contacts, turn the span adjustment screw slowly in a clockwise direction. Con- tinue turning the adjustment screw until you are able to see gaps between the common and both the low and high contacts. A minimum gap provides the greatest sensitiv- ity. The wider the gap, the lower the sensitivity.

If the system includes Air Control Option AR37, the photohelic pressure switch controls the return air damper. The photohelic pressure switch is shipped separately. The photohelic switch uses relays to control between high and low pressure setpoints. When the pressure changes, reaching either setpoint, the beam from an LED to the limiting phototransistor will be cut off by the helix -driven light shield. The resulting signal change is electronically amplified to actuate its DPDT slave relay and switching occurs. Pressure rating is 0" w.c. to .25" w.c. Mount the switch with the scale vertical in a location where the ambient tem- perature is between 20° and 120 °F. Pneumatic pressure sensing lines may be run any distance. Refer to the manufacturer's installation instructions and the wiring diagram to install and connect this switch. Optional Field- Provided Computer Control (applies to systems with Air Control Option AR33 or AR34 and /or with Gas Control Option AG37 or AG51 If the system includes Air Control Option AR33, the discharge damper is con- trolled by a field- supplied 0 -IOVDC or 4 -20 milliamp signal. If the system includes Air Control Option AR34, the computer controls the return air damper. With AG37, the gas valve and burner modulation are controlled by the field - supplied computer signal. With AG51, the gas valve and burner modulation and outside air damper are controlled by the field- supplied computer signal. Follow the signal conditioner 'manufacturer's instructions included with the system for connecting to the field- provided control. Form I -RDF, P/N 148384 (Rev 1), Page 15 10.

See Hazard Levels, page 2. FIGURE 22 - Gas Supply Connection Gas Supply Piping Page 16 Optional Photoelectric Duct Smoke Detector If the system has an optional photoelectric air duct smoke detector, the control is shipped separately for field installation. The sensor must be field- mounted in the discharge duct and electrically connected in the blower section electrical box. Follow the manufacturer's instructions and the wiring diagram for mounting and connecting the control. All piping must be in accordance with the requirements of the National Fuel Gas Code ANSI /Z223.1 (latest edition) or CAN 1 B149.1 and B149.2. Gas supply piping installation must conform with good practice and with all local codes. Read this section of the installation manual to determine the minimum gas supply pressure required to provide a maximum gas capacity. Minimum gas supply pressure is also stated on the heater rating plate. The heater mani- fold terminates at the gas supply connection with a black iron pipe union. See FIGURE 22. Local codes may require a 6" condensate trap. Gas connection is either 1", 1-1/4", or 2" depending on the size of the system. A manual shutoff valve and an adapter with a 1/8" NPT plugged hole for test gauge connection must be installed immediately upstream of the gas supply connection to the appliance.

Supply Pressure Requirement by Manifold Option WARNING: All components of the gas supply system must be leak tested prior to placing equipment in service. NEVER TEST FOR LEAKS WITH AN OPEN FLAME. These direct -fired makeup air systems are designed to operate on a natural gas supply differential pressure range of a minimum of 4.3 -5.0" w.c. plus the mani- fold pressure drop. Maximum supply pressure depends on specific unit firing rate and manifold selection; see below. If the natural gas supply pressure is above the maximum allowed, it is necessary to install a field- supplied step - down gas regulator in the supply line. Order and install the appropriate Gas Regulator Kit, Option CZI (1 ") or CZ2 (1- 1/2 "). These kits include spring - loaded, lockup type regulators that comply with national and local codes speci- fying that type of regulator. Follow the instructions provided with the kit. Mea- sure the gas pressure between the step -down regulator and the unit.

If the gas pressure at this point on a sys- tem equipped with a high gas pressure switch (standard with Manifolds BM 78, 79, 80, and 81 or Option BP2 with other manifolds) exceeds the setpoint, the switch will open the electrical circuit to the burner, stopping all gas flow. The high gas pressure switch is a manual reset device. A low gas pressure switch (Option BP3) will shutoff the gas flow if the gas pressure drops below the setpoint of the low pressure switch. The low gas pressure switch will automatically reset when the gas pressure rises above the setpoint. (NOTE:. Model RDF units manufactured prior to April 1993 installed indoors with optional gas pressure switches require a 3/4" vent line to the outdoors. Beginning with units manufactured April 1993, the gas pressure switches in- corporate a vent limiting device and do not require venting to the outdoors.) Belt Tension - Check belt tension. Proper belt tension is important to the long life of the belt and motor. A loose belt will cause wear and slippage. Too much tension will cause excessive motor and blower bearing wear. If adjustment is required, adjust belt tension by means of the adjusting screw on the motor base until the belt can be depressed 1/2" to 3/4" (FIGURE 24). Tighten the lock nut on the adjusting screw. Be sure the belt is aligned in the pulleys. Motor and Belt Shipping Position for Sizes 2 -80, 2 -120, 3 -180, 3 -260 - To relieve tension on the motor mounting bracket, the belt(s) are taken off the motor and blower sheaves before shipping. The belt(s) are taped to the blower shaft to prevent loss or damage during shipment. Install the belt(s) and adjust for proper belt tension. Blower Pulley - Size 2 -80 and 2 -120 systems equipped with 3 and 5 HP mo- tors with a 15.4" diameter and larger blower pulley or a 7 -1/2 HP and larger motor and all Size 3 -180 and 3 -260 systems are equipped with a split taper bushing in the blower pulley. The split taper bushings must be loosened in order to remove the pulley. Follow these instructions to loosen the bushing. 1) Notice that there are three cap screws in the bushing and two holes without screws, called push -off holes (See FIGURE 25). 2) Remove the three cap screws. 3) Put two of the cap screws into the two push -off holes. Tighten these two screws evenly until the pulley is loosened. 4) Pulley may now be removed from the shaft. Blower Speed Adjustment - Units are set at the factory for the RPM required to meet the CFM and external static pressure specified on the order. If the estimated external static is incorrect, or changes are made to the duct system, the blower RPM may have to be changed. Motors are equipped with adjust- able pitch pulleys which permit adjustment of blower speed. Instructions are included in Paragraph 13, Check - Test -Start for adjusting blower speed. Blower Rotation - Each blower housing is marked for proper rotation. In- structions for checking blower rotation are included in the Check - Test -Start Procedure in Paragraph 13. Motor Loads - Use an ammeter to check motor amps. Amps may be adjusted downward by reducing blower RPM or by increasing duct system static pres- sure. For accurate amps, read the motor manufacturer's rating plate; amps will vary depending upon motor manufacturer. The chart below can be used for sizing line wiring. CAUTION: This chart lists full load amp requirement of standard motor and standard controls. Optional controls will increase amp requirement. Add motor amps and control amps for approximate unit full load amps. System FLA are shown on the rating plate.

WARNING: 1)0 NOT TEST WITH OPEN FLAME. ❑Turn OFF manual gas valves. 10. Turn blower service switch (Electrical Compartment, See FIGURE 26) to OFF position. If present, verify that damper test switch is in TEST position. 1. Prepare system for startup testing -- ❑Attach a slope gauge (0 to 1.0" scale) to the tubing connections in the control compartment. The two connections are located just left of the electrical box. Remove the caps on the 1/8" NPT test connections and attach the slope gauge. (The recommended method for attaching the slope gauge is to use field- supplied 1/8" female NPT x 1/4" OD barbed hose connections.) Diagnostic Lights ❑Connect a "U" -tube manometer to the main burner pressure tap. ❑Check status lights (check at each step in the Startup procedure.) Turn ON disconnect switch. "Circuit Control Power" light is lit. Turn OFF disconnect switch. ❑Turn the disconnect switch ON and the blower service switch to TEST position. "Control Switch Energized ", "Starter Energized ", and if equipped with a freczestat, "Freezestat" lights are lit. After blower obtains normal speed, check for these lights - "Outside Air Cutoff Normal "; "Low Air Pressure Normal ", "Limit Controls Normal "; "High Air Pressure Normal "; and if equipped with options: "Low Gas Pressure Normal "; and/or "High Gas Pressure Normal ". ❑Check for blower rotation. If the blower is turning backwards (see rotation arrows), do the following: Turn the disconnect switch OFF Single -phase units -- rewire motor per instructions on motor wiring plate Three -phase units -- interchange any two motor leads at the motor contactor or starter Turn disconnect switch ON and verify rotation. 2. Measure burner differential air pressure on the slope gauge installed in Preparation Step 1. With the blower operating, differential air should read between -.25" and -.75" w.c. If the slope gauge reading is not within the limits of these numbers, do one of the following: If the slope gauge reading is greater than -.25" (such as -.10" w.c.), adjust the drive to increase the blower speed. (1) Turn disconnect switch OFF. (2) 0 If equipped with a discharge damper, remove opposite sid blower door panel. Turn disconnect switch ON. Check that discharge damper is full open by loosening o tightening the linkage. Turn disconnect switch OFF. Replace door panel. Turn disconnect switch ON and recheck slope gauge. Turn disconnect switch OFF. (3) If reading is still greater than -.25" w.c., adjust drive to increas= fan RPM. For systems with smaller than 7 -1/2 HP motor (a) Loosen belt tension and remove belt. (b) Loosen the setscrew on the side of the pulley away from the motor. (c) Turn adjustable half of the pulley inward to increase blower speed. One turn of the pulley will change speed 8 to 10 %. (d) Tighten the setscrew on the flat portion of the pulley shaft. For systems with 7 -1/2 HP and larger motor (a) Slack off all belt tension by moving the motor toward driven shaft until the belts are free of grooves. For easiest adjustment, remove the belts from the grooves. (b) On the outer locking ring, locate the two locking screws that are directly across from each other. Loosen, but do not remove, those two screws. Do not loosen any other screws. (c) Adjust sheave to desired pitch diameter by turning the outer locking ring. One complete turn of the outer locking If the slope gauge reading is less than -.75" (such as -1.0" w.c.), adjust the drive to decrease the blower speed. (1) Turn disconnect switch OFF.

Check pilot and burner ignition and pilot operation (hot surface ignition) ❑Turn the disconnect switch ON. Turn blower service switch and burner service switch to TEST position. ❑ Observe for ignition through the viewport. Check for lights - Lights listed in prior Steps should be energized. After 15 -20 seconds, the "Pilot Valve" light will light to signal the pilot igni- tion, followed by the "Main Valve" light signaling main burner operation. ❑ With both the burner and blower operating, measure the gas pressure at the burner. Gas pressure should match the required manifold pressure listed on the rating plate. (If pressure does not match the required pres- sure, further testing is required in Step 5.) Remove the manometer. ❑Leak test all connections in the pilot and main burner supply lines. WARNING: DO NOT TEST WITH OPEN FLAME. Page 22 ❑ Check output of pilot flame signal. Use microampmeter; reading should be .5 or greater. 0 T check lockout feature of the pilot ignition system, turn pilot manual shutoff valve OFF. Pilot should lockout after two trials for ignition. To reset unit, open the valve and cycle the main disconnect switch. ❑Turn OFF the manual gas valve. Wait 30 seconds for unit to cool. Return both burner and blower switch to OFF position. Turn OFF disconnect switch. 4. Check pilot pressure -- ❑To check pilot gas pressure, connect a "U" -tube manometer to the pressure tap on the downstream side of the pilot solenoid valve. ❑Put BOTH the blower and burner switch in TEST position. Turn ON disconnect switch. Blower should be energized. ❑Measure pilot gas pressure. Pilot pressure for natural gas should be 3.5" w.c.; pilot pressure for propane gas should be 6" w.c. Pilot pressure should be correct, but if the pressure is not correct, discontinue startup until the pilot gas pressure is regulated correctly. (To adjust pilot pressure, remove the cap from the regulator. Turn adjust- ment clockwise to increase gas pressure or counterclockwise to decrease gas pressure.) When pressure is correct, shut off the gas, remove the manometer, and replace the pressure tap cap on the pilot solenoid valve. 5. Verification of inlet gas pressure -- If, with the blower and burner operating, the inlet main gas pressure measured in Step 3 does not correspond to the minimum stated on the rating plate, check the main burner inlet gas pressure. If the main inlet gas pressure is lower than stated on the rating plate, full burner firing rate will not be achieved. Check main gas supply service regulator for adjustment. ❑Turn disconnect switch OFF. ❑ Re- connect the "U" -tube manometer to the main burner pressure tap. ❑Turn pilot manual shutoff valve back ON. ❑Turn the disconnect switch ON; ignition sequence will occur. ❑Observe the main burner. Light off should occur along the entire length of the burner. ❑ After approximately one minute, record the gas pressure reading on the manometer. NOTE: High outside air temperature on high fire may cause the automatic high limit to trip. Manometer reading may only be available for a very short time. ❑ Turn disconnect switch OFF. ❑Remove the manometer and replace the plug. ❑Remove all jumper wires and reconnect wires. ❑Verify that the blower, burner, and damper switches are in RUN position. CAUTION: If blower or burner service switches are left in TEST position, they will override control from the remote console, switch, or automatic control. ❑ Check that all manual valves are ON. ❑ Close the control door panel; secure latches. ❑Turn ON the disconnect switch. The system is now operational from the control switch, the remote console, or other type of optional automatic control. CAUTION: Burner will not operate if ambient air temperature is above setpoint of outside air control (factory setting is 60 °F). ❑Return this manual to the owner's envelope. Keep for future reference. ❑To check for toxic vapors coming from the surrounding outside atmo- sphere or being produced by the installation (See DANGER below), it is Form 1 -RDF, P/N 148384 (Rev 1), Page 23 13. Check -Test Start (cont'd) After Startup (cont'd) recommended that the tempered makeup air entering the building be tested at its point of discharge from the heating unit. The table below shows limits for various substances including carbon monoxide. Certified, portable detector tubes may be used; follow the manufacturer's instructions. Limits Based on Eight -Hour Exposure and a Five -Day Week (Guide Only) Substance Percent PPM Acetaldehyde .001 10 Carbon Dioxide .250 2500 Carbon Monoxide .001 10 Formaldehyde .000025 0.25 Nitrogen Dioxide .0001 1 Sulphur Dioxide .00005 0.5 Note: At 100 °F rise the CO, concentration will be about 2500 ppm. DANGER: The gas burner in this direct gas -fired system is designed and equipped to provide safe and economically controlled complete combustion. However, if the installation does not permit the burner to receive the proper supply of combustion air, complete combustion may not occur. The result is incomplete combustion which produces carbon monoxide, a poisonous gas that can cause death. Always comply with the combustion air requirements in the installation codes and operating instructions. The amount of air over the burner must be within the specified range. The burner profile plates are set at the factory to match CFM requirements. Do not adjust the burner profile plates without contacting a factory representative. FAILURE TO PROVIDE PROPER COMBUSTION AIR CAN RESULT IN A HEALTH HAZARD WHICH CAN CAUSE PROPERTY DAMAGE, SERIOUS INJURY, AND /OR DEATH. Direct -fired installations should provide for air changes as required by the applicable installation codes.
