IMPORTANT DIRECTIONS
1- Keep the furnace area clear and free of combustible
material, gasoline, and other flammable vapors and
liquids. If installed in an insulated area, furnace must
be kept free of insulating material. Insulating material
may be combustible. Inspect furnace venting system
to make sure it is in place, physically sound, and withĆ
out holes, corrosion, or blockage. Inspect furnace reĆ
turn air duct connection to ensure duct is sealed to the
furnace and terminates outside the space containing
the furnace. Inspect the physical support of the furĆ
nace to guarantee that it is sound without sagging,
cracks or gaps around base and it maintains seal beĆ
tween base and support.
2- DO NOT obstruct air flow to unit. Unit must receive an
unobstructed flow of combustion and ventilating air.
3- DO NOT store chlorine or fluorine products near unit
or introduce these products into the combustion air.
These products can cause furnace corrosion.
LIGHTING INFORMATION AND OPERATION
WARNING
If you do not follow these instructions exactly,
a fire or explosion may result causing property

do not try to repair it, call a qualified service technician.
Force or attempted repair may result in a fire or explosion.

ignition system. Do not attempt to manually light pilots on
these furnaces. Each time thermostat calls for heat, the piĆ
lot will be automatically lit. The pilot does not burn when
there is no call for heat on units with electronic ignitions.
