START-UP PROCEDURES

TO START THE FURNACE
LIGHTING INSTRUCTIONS
This appliance is equipped with a hot
surface ignition device. This device lights
the main burners each time the room
thermostat calls for heat. See the lighting
instructions on the furnace.
During initial start-up, it is not unusual for
odor or smoke to come out of any room
registers. To ensure proper ventilation, it
is recommended to open windows and
doors, before initial firing.
The furnace has a negative pressure
switch that is a safety during a call for
heat. The induced draft blower must pull
a negative pressure on the heat
exchanger to close the negative pressure
switch. The induced draft blower must
maintain at least the negative pressure
switch set point for the furnace to oper-
ate. If the induced draft blower fails to
close or maintain the closing of the nega-
tive pressure switch, a "no heat call"
would result.
1. Remove the burner compartment
control access door.
2. IMPORTANT: Be sure that the man-
ual gas control has been in the
"OFF" position for at least five min-
utes. Do not attempt to manually
light the main burners.
3. Set the room thermostat to its lowest
setting and turn off the furnace elec-
trical power.
4. Turn the gas control knob to the
"ON" position.
5. Replace the burner compartment
control access door.
