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
