CAUTION
Before attempting to perform any maintenance, turn the
electrical power to unit OFF at the disconnect switch.
NOTICE
Any additions, changes, or conversions required in order
for the appliance to satisfactorily meet the application
needs must be made by a licensed professional installer
(or equivalent) using factory-specified and approved
parts.
Safety Instructions
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 material may be combustible.
2 - After any heavy snow, ice or frozen fog event, the
furnace vent pipes may become restricted. Always
check the vent system and remove any snow or ice
that may be obstructing the plastic intake or exhaust
pipes.
3 - DO NOT obstruct air flow to unit. Unit must receive
an unobstructed flow of combustion and ventilating
air. DO NOT block or obstruct air openings on
the furnace or air openings to the area in which
the furnace is installed. Take care to maintain
established clearances surrounding the furnace.
4 - DO NOT store chlorine or fluorine products near
unit or introduce these products into the combustion
air. These products can cause furnace corrosion.
5 - 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.
WARNING
The blower door must be securely in place when the
blower and burners are operating. Gas fumes, which
could contain carbon monoxide, can be drawn into the
living space resulting in personal injury or death.
Your furnace is a gas appliance. It is critical that the gas
supplied to the unit be completely burned to avoid the pro-
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.
Carbon monoxide gas is invisible, odorless and toxic.
The exhaust vent for this furnace must be leak-free and
must be securely connected to the furnace flue collar
at all times. For your safety and to fulfill the terms of
the limited warranty, a licensed professional service
technician (or equivalent) must annually inspect this
furnace and its vent system.
CARBON MONOXIDE POISONING HAZARD
Failure to follow instruction could result in severe personal
injury or death due to carbon monoxide poisoning, if
combustion products infiltrate into the building.
Check that all openings in the outside wall around
the vent (and air intake) pipe(s) are sealed to prevent
infiltration of combustion products into the building.
Check that furnace vent (and air intake) terminal(s) are
not obstructed in any way during all seasons.
Exposure to carbon monoxide gas can cause personal in-
jury and even death to all occupants, including pets. Any
item that is powered by or gives off heat from a combus-
tion process (including lawn mowers, automobiles, and
fireplaces) has the potential to produce carbon monoxide
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 detectors are
available at reasonable retail prices. Contact your Lennox
dealer for more details about this investment in your safe-
ty.
Your furnace is designed to meet standards set by nation-
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 op-
erating environment. It is your responsibility to ensure that
this appliance is maintained. Proper maintenance is crit-
ical for your safety and the satisfactory operation of the
product. Lennox strongly recommends annual inspec-
tion and maintenance of this appliance. Contact your
Lennox dealer for an inspection by a licensed professional
service technician (or equivalent).
