IMPORTANT
Any additions, changes, or conversions re-
quired in order for the appliance to satisfactorily
meet the application needs must be made by a
Lennox service technician using factory speci-
fied and approved parts.
IMPORTANT DIRECTIONS
1 - Keep the furnace area clear and free of combustible
material, gasoline, and other flammable vapors and liq-
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.
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.
Use only your hand to push in or turn the gas control
knob. Never use tools. If the knob will not push in or turn
by hand, do not try to repair it, call a qualified service
technician. Force or attempted repair may result in a fire
or explosion.

G24E units are equipped with an electronic ignition sys-
tem. Do not attempt to manually light burners on these

er will automatically light.
