HEATANTICIPATORSETTING

The heat anticipator in the room thermostat must be correctly adjusted to obtain the proper number of cycles per hour and to prevent “overshooting” of the setting. Set the heat anticipator set- ting to 0.7 amps. Follow the thermostat manufacturer’s instruc- tions on how to adjust the heat anticipator setting.

DRAIN TRAPPRIMING

The drain trap must be primed prior to furnace startup. To prime, fill the drain trap with water. This ensures proper furnace drainage upon startup and prohibits the possibility of flue gases escaping through the drain system.

FURNACEOPERATION

Purge gas lines of air prior to startup. Be sure not purge lines into an enclosed burner compartment.

Check for leaks using an approved chloride-free soap and water solution, an electronic combustible gas detector, or other approved method. Verify that all required kits (propane gas, high altitude, etc.) have been appropriately installed.

CAUTION

TO PREVENT UNRELIABLE OPERATION OR EQUIPMENT DAMAGE, THE INLET GAS SUPPLY PRESSURE MUST BE AS SPECIFIED ON THE UNIT RATING PLATE WITH ALL OTHER HOUSEHOLD GAS FIRED APPLIANCES OPERATING.

The line pressure supplied to the gas valve must be within the range specified below. The supply pressure can be measured at the gas valve inlet pressure boss or at a hose fitting installed in the gas piping drip leg. The supply pressure must be measured with the burners operating. To measure the gas supply pressure, use the following procedure.
