Important Directions
1 - Keep the furnace area clear and free of combustible
material, petrol, and other flammable vapours and liqĆ
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 furĆ
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 air is 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 flue gas may result in incomplete combustion 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 unit be completely burned to avoid the proĆ
duction of carbon monoxide gas. Complete combustion
of the gas requires, but is not limited to, correct gas presĆ
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 monĆ
oxide gas. Because of this, Lennox recommends the
use of a carbon monoxide detector in your home,
even if you do not own gas appliances. Reliable deĆ
tectors are available at reasonable retail prices. ConĆ
tact your independent Lennox dealer for more details
about this investment in your safety.
Your furnace is designed to meet standards set by nationĆ
al agencies, and to operate safely when properly installed
and maintained. However, the unit's performance can be
greatly impacted by the individual installation and the opĆ
erating environment. It is your responsibility to ensure
that this appliance is maintained. Proper maintenance is
critical for your safety and the satisfactory operation of the
product. Lennox strongly recommends annual inĆ
spection and maintenance of this appliance. Contact
your independent Lennox dealer for an inspection by a
qualified service technician.
