Importa t Directio s
1 - Keep the furnace area clear and free of combustible
material, gasoline, and other flammable vapors and
liquids. If it is installed in an insulated area, the furnace
must be kept free of insulating material. Insulating maĆ
terial may be combustible.
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 retur air from a room where this furĆ
ace, or a y other gas applia ce (ie., a water heatĆ
er), is i stalled. When return air is drawn from a room,
a negative pressure is created in the room. If a gas apĆ
pliance 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.
WARNING
The blower door must be securely i place whe the
blower a d bur ers are operati g. Gas fumes, which
could co tai carbo mo oxide, ca be draw i to
the livi g space resulti g i perso al i jury or death.
Your fur ace is a gas applia ce. 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 pressure
and gas flow rate, adequate combustion air and proper
venting.
WARNING
Carbo mo oxide gas is i visible, odorless, a d
toxic.
Exposure to carbon monoxide gas can cause personal injuĆ
ry and even death to all occupants, including pets. ny item
that is powered by, or gives off heat from, a combustion proĆ
cess (including lawn mowers, automobiles, and fireplaces)
has the potential to produce carbon monoxide gas. Because
of this, Le ox recomme ds the use of a carbo mo oxĆ
ide detector i your home, eve if you do ot ow gas
applia ces. Reliable detectors are available at reasonable
retail prices. Contact your Lennox dealer for more details
about this investment in your safety.
Your furnace is designed to meet standards set by nationĆ
al agencies. It should operate safely when properly
installed and maintained. However, the unit's perforĆ
mance can be greatly impacted by the individual installaĆ
tion and the operating environment. It is your responsibilĆ
ity to ensure that this appliance is maintained. Proper
maintenance is critical for your safety and the satisfactory
operation of the product. Le ox stro gly recomme ds

tioned and sloped upward. The vent connector must be
physically sound, without holes or excessive corrosion.
Inspect the furnace return air duct connection. The duct
must be sealed to the furnace and it must terminate outside
the space containing the furnace.
Inspect the physical support of the furnace to guarantee
that it is sound. The support must not sag and must not
have cracks or gaps around the base of the furnace. There
must be a seal between the furnace base and the support.
During a seasonal check, the service technician will inĆ
spect the indoor blower and the burner flames along with
the venting system.
Blower

Safety Precautio s
If you discover a y of the followi g, shut dow your
u it a d co tact a Le ox dealer for a i spectio by a
qualified tech icia .
DIf you repeatedly hear any new or unfamiliar sounds
while your unit is operating, there may be a problem. For
example, poorly performing burners can produce unfaĆ
miliar noises.
DIf you smell any unusual odors, your unit may be operatĆ
ing improperly. For example, units can give off unfamilĆ
iar odors if components are required to operate in abĆ
normal conditions.
DLook for visible signs of a malfunctioning unit. Examples
include unusual amounts of condensate on windows inĆ
side your house, visibly burnt components or unusual
dirt or rust accumulations on the vent pipe or in the unit.
DIf you experience headache, nausea, fatigue, or dizziĆ
ness, the cause could be exposure to carbon monoxide
gas. This is often misdiagnosed as the flu because
symptoms are similar. If you suffer from flu-like sympĆ
toms that are exaggerated at home, but seem to subĆ
side while you are away from the house, exposure to
carbon monoxide could be the cause.
Your vigilance may pay off in early detection of a problem
before either personal injury or property damage occurs.
Do not hesitate to contact a qualified service technician as
an investment in your well being.

Ve t pipe - Must be inspected for signs of water, damaged
or sagging pipe, or disconnected joints.
U it appeara ce - Must be inspected for rust, dirt, signs
of water, burnt or damaged wires, or components.
Blower access door - Must be properly in place and proĆ
vide a seal between the return air and the room where the
furnace is installed.
Retur air duct - Must be properly attached and provide
an air seal to the unit.
Operati g performa ce - Unit must be observed during
operation to monitor proper performance of the unit and the
vent system.
Combustio gases - Flue products must be analyzed and

Problems detected during the inspection may make it necĆ
essary to temporarily shut down the furnace until the items
can be repaired or replaced.
Pay atte tio to your fur ace. Situations can arise beĆ
tween annual furnace inspections that may result in unsafe
operation. For instance, items innocently stored next to the
furnace may obstruct the combustion air supply. This could
cause incomplete combustion and the production of carĆ
bon monoxide gas.
