WARNING:
Before placing the furnace in service, it must be
checked to ensure it is equipped for the type of gas
being used. The burner flame must be observed
and adjusted if necessary. Failure to observe this
caution may result in unsafe operation, explosion
and/or fire, or asphyxiation. See the Gas Supply
and Combustion Air sections.
•
The first operation of the furnace after any home
setup must be performed by a qualified service
technician.
• BEFORE STARTUP: Smell all around the furnace for
gas and next to the floor. Some gas is heavier than air
and may settle on the floor.
• Do not use this furnace if any part has been under
water. Immediately call a service technician to inspect
the furnace and to replace any part of the gas valve or
control system which has been under water.
WARNING:
Close the hinged fire door. If door is left open
or spring is broken it may allow products of
combustion into the living space by the furnace
blower, resulting in possible asphyxiation.
WARNING:
Should overheating occur, or the gas supply fails
to shut off, shut off the manual gas valve to the
furnace before shutting off the electrical supply.
AVERTISSEMENT :
En cas de surchauffe, ou si l’alimentation de gaz
omet de s’arrêter, fermez le robinet de gaz manuel
à la fournaise avant de couper l’alimentation
électrique.
Operating Instructions
(Direct Ignition Furnaces)
Direct ignition furnaces do not have a pilot. Ignition is
accomplished by a hot surface ignitor. A circuit board
takes care of all timing functions. After lighting, the circuit
board uses the ignitor as a flame sensor, shutting off gas
should the flame go out. There are no external relays or
timing devices.
Do not try to light this furnace by hand.
The circuit board is not field serviceable.
1. Set the thermostat to the lowest setting.
2. Turn off all electric power to the appliance.
3. Remove the furnace door and turn off the gas valve.
Push in and turn the gas control knob clockwise to
OFF
.
See
4. Wait ten (10) minutes to clear out any gas. If you smell
gas,
STOP!
and follow the Safety Information. If you
do not smell gas, proceed to step 5.
