The unit may be installed directly on wood floors or on Class A, Class B, or Class C roof covering material. To avoid possible personal injury, a safe, flat surface for service personnel should be provided. Important: If using bottom discharge with roof curb, ductwork should be attached to the curb prior to installing the unit. Ductwork dimensions are shown in roof curb installation instructions.
The rating plate is stamped with the model number, type of gas and gas input rating. Make sure the unit is equipped to operate on the type of gas available. Conversion to LP gas is permitted with the use of the factory authorized conversion kit LPM-07, for use with single stage models, or LPM08, for use with two-stage models. See table below. The rating plate is stamped with the model number, type of gas and gas input rating. Make sure the unit is equipped to operate on the type of gas available.
WARNING To avoid property damage or personal injury, BE SURE THERE IS NO OPEN FLAME IN THE VICINITY DURING AIR BLEEDING. PROPANE GAS INSTALLATIONS WARNING To avoid property damage, personal injury or death due to fire or explosion caused by a propane gas leak, install a gas detecting warning device. Since rust can reduce the level or odorant in propane gas, a gas detecting warning device is the only reliable way to detect a propane gas leak.
ELECTRICAL WIRING See below for typical propane gas piping. 5 to 15 PSIG (20 PSIG Max.) First Stage Regulator Thermostat Location Mount the thermostat approximately five feet above the floor, in an area that has an inside, vibration-free wall and has good air circulation. Continuous 11" W.C. 200 PSIG Maximum Movement of air must not be obstructed by furniture, door, draperies, etc.
Y2 C Y1 W1 W2 ( Thermostat Two-Stage Heating with Two-Stage Cooling ( R G R C W1W2 G Y1 Y2 Furnace Integrated Control Module Two-Stage Heating with Two-Stage Cooling Thermostat Diagram Single Stage Thermostat - Two-Stage Models To use a single stage thermostat, move jumper located to the left of the terminal strip labeled “Stage Delay” from NONE to “5” or “10” minutes. This selection will cause the control to run on low stage for the selected time (5 or 10 minutes) then shift to HIGH STAGE.
NOTE: A dedicated ground wire must be run from the unit to the electrical panel. DO NOT use gas piping, or conduit as an electrical ground. Low voltage wiring from the unit control panel to the thermostat requires coded cable. See below for ground level and rooftop wiring. NOTE: The unit transformer is factory connected for 240V operation. If the unit is to operate on 208V, reconnect the transformer primary lead as shown on the unit wiring diagram.
Filters Installation - Combustion Air Intake Hood 1. Locate the second hood. 2. Using the three screws provided, attach the hood (with the opening facing down) to the heat exchanger access door. CAUTION To prevent property damage due to fire and loss equipment efficiency or equipment damage due to dust and lint build up on internal parts, never operate unit without an air filter installed in the return air system.
Two-Stage Models: The fan runs at low cool speed for the off delay period. This allows additional cooling from the indoor coil to be transferred to the conditioned space. Then, the indoor fan stops. 3. The spark igniter and gas valve energizes for 7 seconds. NOTE: The igniter produces a very intense electrical spark that ignites the gas. 4. Main burners light and control detects presence of flame. 5. The 30-second HEAT FAN ON delay time begins after the main burners light. 6.
9. Replace the heat exchanger door on the side of the unit. 10. Open the manual gas valve external to the unit. 11. Turn on the electrical power supply to the unit. 12. Set the thermostat to desired setting. Rollout Protection Gas Supply And Manifold Check Gas supply pressure and manifold pressure with the burners operating must be as specified on the rating plate. NOTE: Use adapter kit #0151K00000S to measure gas pressure on White-Rodgers 36J22 and 36G54 gas valves.
The line pressure supplied to the gas valve must be within the range specified in the Inlet Gas Supply Pressure table. The supply pressure can be measured at the gas valve inlet pressure tap or at a hose fitting installed in the gas piping drip leg. The supply pressure must be measured with the unit OFF. To measure inlet pressure, use the following procedure. 8. Measure the gas supply pressure with burners firing. Adjust supply pressure using the Inlet Gas Supply Pressure table shown below.
WARNING HIGH VOLTAGE Disconnect all power before servicing or installing this unit. Multiple power sources may be present. Failure to do so may cause property damage, personal injury or death. . This valve is shipped from the factory with the regulator preset (see control label). Mode Consult the appliance rating plate to ensure burner manifold pressure is as specified. If another outlet pressure is required, follow these steps. 1.
NOTE: Air temperature rise is the temperature difference between supply and return air. 2. With the unit operating, time the smallest dial on the meter for one complete revolution. If this is a 2 cubic foot dial, divide the seconds by 2; if it is a 1 cubic foot dial, use the seconds as is. This gives the seconds per cubic foot of gas being delivered to the unit. 3. INPUT=GAS HTG VALUE x 3600 / SEC.
Blower Speed Adjustments Refer to the wiring diagram in the appendix to verify speed tap settings. LOCOOL U6 HICOOL U7 LOHEAT U3 All models are equipped with EEM motors. EEM motors are constant torque motors with very low power consumption. This motor is energized by 24V. Adjust the CFM for the unit by changing the 24V low voltage leads to the speed terminal block on the motor.
Refrigerant Charge Check After completing airflow measurements and adjustments the unit’s refrigerant charge must be checked. The unit comes factory charged, but this charge is based on 325 CFM per ton and minimum ESP per AHRI test conditions (generally between .15 -.28 ESP). When air quantity or ESP is different than above, the refrigerant charge must be adjusted to the proper amount. All package units with fixed orifice devices are charged using the super heat method at the compressor suction line.
External Lockout An external lockout occurs if the integrated ignition control determines that a measurable combustion cannot be established within three (3) consecutive ignition attempts. If flame is not established within the seven (7) second trial for ignition, the gas valve is de-energized, 15 second inter-purge cycle is completed, and ignition is reattempted. The control will repeat this routine three times if a measurable combustion is not established.
Rollout Limit If the burner flames are not properly drawn into the heat exchanger, the flame rollout protection device will open. Possible causes are restricted or blocked flue passages, blocked or cracked heat exchanger, a failed induced draft blower, or insufficient combustion air. The rollout protection device is a manual reset limit located on the burner bracket. The cause of the flame rollout must be determined and corrected before resetting the limit.
MAINTENANCE Flame Sensor (Qualified Servicer Only) A drop in the flame current can be caused by a nearly invisible coating on the flame sensor. This coating, created by the fuel or combustion air supply, can be removed by carefully cleaning the flame sensor with steel wool. NOTE: After cleaning, the microamp signal should be stable and in the range of 4 - 6 microamps DC. WARNING HIGH VOLTAGE Disconnect all power before servicing or installing this unit. Multiple power sources may be present.
CAUTION Label all wires prior to disconnection when servicing controls. Wiring errors can cause improper and dangerous operation. Check the burner flames for: 1. Good adjustment 2. Stable, soft and blue 3. Not curling, floating, or lifting off. CAUTION Always verify proper operation after servicing. Burner Flame For further information on the yearly inspection, consult the User Manual. It is recommended that a qualified servicer inspect and service the unit at least once each year.
