Safety Instructions

CAUTION

Before attempting to perform any service or mainte- nance, 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 ap- plication needs must be made by a licensed profes- sional installer (or equivalent) using factory−speci- fied and approved parts.

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 − 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 clear- ances surrounding the furnace.

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 return air from a room where this fur- nace, or any other gas appliance (ie., a water heat- er), is installed. When return air is drawn from a room, a negative pressure is created in the room. If a gas ap- 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 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.

WARNING

Asphyxiation Hazard

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.

Exposure to carbon monoxide gas can cause personal inju- ry and even death to all occupants, including pets. Any item that is powered by, or gives off heat from, a combustion pro- cess (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 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 critical for your safety and the sat- isfactory operation of the product. Lennox strongly rec- ommends annual inspection and maintenance of this appliance. Contact your Lennox dealer for an inspection by a licensed professional service technician.
