Use only your hand to push in or move the gas control lever or switch. Never use tools. If the lever or switch will not push in or move by hand, do not try to repair it, call a qualified service technician. Force or attempted repair may result in a fire or explosion.
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 ventilat3 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 com3 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 distrib3 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 pro3 duction of carbon monoxide gas. Complete combustion of the gas requires, but is not limited to, correct gas pres3 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 rea3 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 nation3 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 op3 erating environment. It is your responsibility to ensure that this appliance is maintained. Proper maintenance is critical for your safety and the satisfactory operation of the product. Lennox strongly recommends annual in. spection and maintenance of this appliance. Contact your independent Lennox dealer for an inspection by a qualified service technician.
