Notice to Homeowner
This furnace is equipped with safety devices that protect
you and your property. If one or more of these devices is
activated, furnace operation will stop. If your home is left
unattended for an extended period of time, equipment operation must be checked periodically. If this is not possible,
GAS VALVE AND
MANIFOLD
the water supply to the house should be shut off and the
pipes should be drained. This will prevent problems associ-
ated with a NO HEAT condition (frozen pipes, etc.)
CAUTION
Before attempting to perform any service or maintenance, turn the electrical power to unit OFF at the
disconnect switch.

WARNING
Do not set thermostat below 60°F (16°C) in heating
mode. Setting thermostat below 60°F (16°C) reduces
the number of heating cycles. Damage to the unit
may occur that is not covered by the warranty.
WARNING
If overheating occurs or if gas supply fails to shut off,
shut off the manual gas valve to the furnace before
shutting off electrical supply.
WARNING
Do not use this furnace if any part has been underwater. A flood−damaged furnace is extremely dangerous. Attempts to use the furnace can result in
fire or explosion. Immediately call a licensed professional service technician (or equivalent) to inspect the furnace and to replace all gas controls,
control system parts, and electrical parts that have
been wet or to replace the furnace, if deemed necessary.
NOTICE
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 fur-
nace, 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.
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.
WARNING
Improper installation, adjustment, alteration, service
or maintenance can cause property damage, personal injury or loss of life. Installation and service must
be performed by a licensed professional installer (or
equivalent), a service agency, or the gas supplier.
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 ma-
terial may be combustible.
2 − After any heavy snow, ice or frozen fog event, the fur-
nace 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.
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.
WARNING
Carbon monoxide gas is invisible, odorless and
toxic.
Exposure to carbon monoxide 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. Because
of this, Lennox recommends the use of a carbon monox-
ide 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 safety.
Your furnace is designed to meet standards set by national agencies, and to operate safely when properly installed
and maintained. However, the unit’s performance can be
