UPRIGHT INSTALLATIONS

Depending on the installation and/or customer preference,
differing filter arrangements can be applied. Filters can be
installed in the central 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. Review and follow the filter sizes given in
the Specifications Sheet to ensure proper unit perfor-
mance.
NOTE: Internal filter retention is not provided on GULA
furnaces.
The following figures show possible filter locations.

XIV. Startup Procedure &
Furnace must have a 115 VAC power supply properly
connected and grounded. Proper polarity must be main-
tained for correct operation. In addition to the following
start-up and adjustment items, refer to further information
in Section XVI, Operational Checks.

HEAT ANTICIPATOR SETTING

The heat anticipator in the room thermostat must be cor-
rectly adjusted to obtain the proper number of cycles per
hour and to prevent "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.

DRAIN TRAP PRIMING

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.

FURNACE OPERATION

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 (pro-
pane gas, high altitude, etc.) have been appropriately
installed.

Furnace Startup

1. Close the manual gas shut-off valve external to the
furnace.
2. Turn off the electrical power to the furnace.
3. Set the room thermostat to the lowest possible setting.
4. Remove the burner compartment door.
NOTE: This furnace is equipped with an ignition device
which automatically lights the burner. Do not try to light the
burner by hand.
5. Move the furnace gas valve manual control to the OFF
position.
6. Wait five minutes then smell for gas. Be sure check
near the floor as some types of gas are heavier than air.
7. If you smell gas after five minutes, immediately follow
the instructions on page 4 of this manual. If you do not
smell gas after five minutes, move the furnace gas
valve manual control to the ON position.
8. Replace the burner compartment door.
9. Open the manual gas shut-off valve external to the
furnace.
10. Turn on the electrical power to the furnace.
11. Adjust the thermostat to a setting above room tempera-
ture.
12. After the burners are lit, set the thermostat to desired
temperature.
