Furnace must have a 115 VAC power supply properly connected
and grounded. Proper polarity must be maintained for correct op-
eration. An interlock switch prevents furnace operation if the blower
door is not in place. Keep the blower access door in place except for
inspection and maintenance.
This furnace is also equipped with a self-diagnosing electronic con-
trol module. In the event a furnace component is not operating prop-
erly, the control module LED will flash on and off in a factory-pro-
grammed sequence, depending on the problem encountered. This
light can be viewed through the observation window in the blower
access door. Refer to the Troubleshooting Chart for further explana-
tion of the lighting codes.
On new installations, or if a functional part such as the gas valve,
pressure switch, or limit control has been replaced, verify that the
furnace is operating properly after servicing.
Check furnace operation as outlined in the following instructions. If
any sparking, odors, or unusual noises are encountered, shut off
electrical power and recheck for wiring errors, or obstructions in or
near the blower motors. Various shipping materials must be removed
before the blower motor is operated. In addition to the following
start-up and adjustment items, refer to further information in Section
XIII, Operational Checks.

EAT NTICIPATOR ETTING
The heat anticipator in the room thermostat must be correctly ad-
justed 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.

URNACE OPERATION
Purge gas lines of air prior to start-up. Do 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.

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 tap 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
