NSTALLATIONS
Depending on the installation and/or customer preference, differing
filter arrangements can be applied. Filters can be installed in the cen-
tral return register or a side panel external filter rack kit (upflows). As
an alternative a media air filter or electronic air cleaner can be used as
the requested filter.

XIV. STARTUP PROCEDURE & ADJUSTMENT
Furnace must have a 115 VAC power supply properly connected
and grounded. Proper polarity must be maintained for correct op-
eration. In addition to the following start-up and adjustment items,
refer to further information in Section XVI, Operational Checks.

ETTING
The heat anticipator in the room thermostat must be correctly ad-
justed to obtain the proper number of cycles per hour and to pre-
vent “overshooting” of the setting. Set the heat anticipator setting to
0.7 amps. Follow the thermostat manufacturer’s instructions on
how to adjust the heat anticipator setting.

RIMING
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. Air conditioning condensate may be drained
into the furnace trap.

OPERATION
Purge gas lines of air prior to startup. Be sure not to purge lines into
an enclosed burner compartment. Follow NFPA 54, National Fuel Gas
Code 8.3 for proper purging methods. In Canada, follow approved
purging methods in B149.1

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.
