WARNING
Product contains fiberglass wool.
Disturbing the insulation in this product during installation, maintenance, or repair will expose you to fiberglass wool dust. Breathing this may cause lung cancer. (Fiberglass wool is known to the State of California to cause cancer.)
Fiberglass wool may also cause respiratory, skin, and eye irritation.
To reduce exposure to this substance or for further information, consult material safety data sheets available from address shown below, or contact your supervisor.

WARNING
If overheating occurs or if gas supply fails to shut off, shut off the manual gas valve to the appliance before shutting off electrical supply.
WARNING
Do not use this furnace if any part has been under. water. Immediately call a qualified service techni. cian to inspect the furnace and to replace any part of the control system and any gas control which has been under water.

Important Directions
1 - Keep the furnace area clear and free of combustible material, gasoline, and other flammable vapors and
liquids. If installed in an insulated area, furnace must be kept free of insulating material. Insulating material
may be combustible.
2- DO NOT obstruct air flow to unit. Unit must receive an unobstructed flow of combustion and ventilat2 ing 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 the return air from a room where
another gas appliance (ie., a water heater) is
installed. Even though this furnace draws its com2
bustion air from outside of the structure, other gas
appliances that share a utility room may not. 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 distrib2 uted through 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 pro2
duction of carbon monoxide gas. Complete combustion
of the gas requires, but is not limited to, correct gas pres2
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 monoxide gas. Because
of this, Lennox recommends the use of a carbon mon.
oxide detector in your home, even if you do not own
gas appliances. Reliable detectors are available at rea2
sonable retail prices. Contact your independent Lennox
dealer for more details about this investment in your safety.
Your furnace is designed to meet standards set by nation2
al agencies, and to operate safely when properly installed
and maintained. However, the unit's performance can be
