3. When there is a cooling demand, the indoor blower will run on the cooling speed. Generator Use - Voltage Requirements • The furnace requires 120 volts ± 10% (Range: 180 volts to 132 volts) • The furnace operates at 60 Hz ± 5% (Range: 57 Hz to 63 Hz) • The furnace integrated control requires both polarity and proper ground. Both polarity and proper grounding should be checked before attempting to operate the furnace on either permanent or temporary power. • Generator should have a wave form distortion of less than 5% RHD Figure 52 TYPICAL FIELD WIRING DIAGRAM WARNING: ELECTRIC SHOCK HAZARD, CAN CAUSE INJURY OR DEATH. UNIT MUST BE GROUNDED IN ACCORDANCE WITH NATIONAL AND LOCAL CODES NOTE: IF ANY WIRE IN THIS APPLIANCE IS REPLACED, IT MUST BE REPLACED WITH WIRE OF LIKE SIZE, RATING, INSULATION THICKNESS AND TERMINATION FIELD SUPPLIED ACC.

A flood-damaged furnace is extremely dangerous. Attempts to use the furnace can result in fire or explosion. Immediately call a qualified service technician to inspect the furnace and to replace all gas controls, control system parts, and electrical parts that have been wet or to replace the furnace, if deemed necessary. WARNING Danger of explosion. Can cause injury or product or property damage. Should the gas supply fail to shut off or if overheating occurs, shut off the gas valve to the furnace before shutting off the electrical blower deck, before performing any service procedure. CAUTION Before attempting to perform any service or maintenance, turn the electrical power to unit OFF at disconnect switch. BEFORE LIGHTING the unit, smell all around the furnace area for gas. Be sure to smell next to the floor because some gas is heavier than air and will settle on the floor. The gas valve on the unit is equipped with a gas control switch (lever). Use only your hand to move switch. Never use tools. If the switch will not move by hand, do not try to repair it. Force or attempted repair may result in a fire or explosion. Placing the furnace into operation: This furnace is equipped with an automatic hot surface ignition system. Do not attempt to manually light burners on this furnace. Each time the thermostat calls for heat, the burners will automatically light. The ignitor does not get hot when there is no call for heat on these units. 506501-01 Issue 1031 Page 37 of 48 Priming Condensate Trap The condensate trap should be primed with water prior to start-up to ensure proper condensate drainage. Either pour 10 fl. oz. (300 ml) of water into the trap, or follow these steps to prime the trap: 1. Follow the lighting instructions to place the unit into operation. 2. Set the thermostat to initiate a heating demand. 3. Allow the burners to fire for approximately 3 minutes. 4. Adjust the thermostat to deactivate the heating demand. 5. Wait for the combustion air inducer to stop. Set the thermostat to initiate a heating demand and again allow the burners to fire for approximately 3 minutes. 6. Adjust the thermostat to deactivate the heating demand and wait for the combustion air inducer to stop. At this point, the trap should be primed with sufficient water to ensure proper condensate drain operation. WARNING If you do not follow these instructions exactly, a fire or explosion may result causing property damage, personal injury or death. Gas Valve Operation (Figure 55) 1. STOP! Read the safety information at the beginning of this section. 2. Set the thermostat to the lowest setting. 3. Turn OFF all electrical power to the unit. 4. This furnace is equipped with an ignition device which automatically lights the burners. Do not try to light the burners by hand. 5. Remove the upper access panel. 6. Move gas valve switch to OFF. See Figure 55. 7. Wait five minutes to clear out any gas. If you then smell gas, STOP! Immediately call your gas supplier from a neighbor’s phone. Follow the gas supplier’s instructions. If you do not smell gas go to next step. 8. Move gas valve switch to ON. See Figure 55. GAS VALVE SHOWN IN ON POSITION Figure 55 9. Replace the upper access panel. 10. Turn on all electrical power to the unit. 11. Set the thermostat to desired setting. NOTE: When unit is initially started, steps 1 through 11 may need to be repeated to purge air from gas line. 12. If the appliance will not operate, follow the instructions “Turning Off Gas to Unit” and call your service technician or gas supplier. Turning Off Gas to Unit 1. Set the thermostat to the lowest setting. 2. Turn off all electrical power to the unit if service is to be performed. 3. Remov...
