Important Directions
1 - Keep the furnace area clear and free of combustible
material, gasoline, and other flammable vapors andliq-
uids. 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 without
holes, corrosion, or blockage. Inspect furnace return
air duct connection to ensure duct is sealed to the fur-
nace and terminates outside the space containing the
furnace. Inspect the physical support of the furnace to
guarantee that it is sound without sagging, cracks or
gaps around base and it maintains seal between 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.
4-
DO NOT draw return air from a room where this
furnace, or any other gas appliance (ie., a water
heater), is installed.
When return airis drawn from a
room, a negative pressure is created in the room. If a
gas appliance is operating in a room with negative
pressure, the flue products can be pulled back down
the vent pipe and into the room. This reverse flow of
the fluegas may result in incompletecombustion and
the formation of carbon monoxide gas. This toxic gas
might then be distributed throughout the house by
the furnace duct system.
Your furnace is a gas appliance.
It is critical that the gas
supplied to the unitbe completely burned toavoid the pro-
duction of carbon monoxide gas. Complete combustion
of the gas requires, but is not limited to, correct gas pres-
sure and gas flow rate, adequate combustion, air, and
proper venting.
WARNING
Carbon monoxide gas is invisible, odorless, and
toxic.
Exposure to this gas can cause personal injury and even
death to all occupants, including pets. Any item that is
powered by or gives off heat from a combustion process
(including lawn mowers, automobiles, and fireplaces)
has the potential to produce carbon monoxide gas. Be-
cause of this,
Lennox recommends the use of a car-
bon monoxide detector in your home, even if you do
not own gas appliances.
Reliable detectors are avail-
able at reasonable retail prices. Contact your indepen-
dent Lennox dealer for more details about this invest-
ment in your safety.

Lighting Information and Operation
WARNING
If you do not follow these instructions exactly, a fire
or explosion may result causing property damage,
personal injury or loss of life.
BEFORE LIGHTING smell all around the appliance area
for gas. Be sure to smell next to the floor because some
gas is heavier than air and will settle on the floor.
