Important Directions, Thermostats | Lennox International Inc G27M

Important Directions

1 - Keep the furnace area clear and free of combustible material, gasoline, and other flammable vapors and liq& uids. If installed in an insulated area, furnace must be kept free of insulating material. Insulating material may be combustible. Inspect furnace venting system to make sure it is in place, physically sound, and without holes, corrosion, or blockage. Inspect furnace return air duct connection to ensure duct is sealed to the fur& nace and terminates outside the space containing the furnace. Inspect the physical support of the furnace to guarantee that it is sound without sagging, cracks or gaps around base and it maintains seal between base and support.

2 - DO NOT obstruct air flow to unit. Unit must receive an unobstructed flow of combustion and ventilating 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 return air from a room where this furnace, 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.

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 pres&

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 pow& ered by or gives off heat from a combustion process (in&

cluding 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 reason& able 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 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 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.

Lighting Information and Operation

WARNING

If you do not follow these instructions exactly, a fire or explosion may result causing property damage, personal injury or loss of life.

BEFORE OPERATING smell all around the appliance area for gas. Be sure to smell next to the floor because some gas is heavier than air and will settle on the floor.

Use only your hand to turn the gas control knob. Never use tools. If the knob will not turn by hand, do not try to repair it, call a qualified service technician. Force or attempted repair may result in a fire or explosion.

Placing Furnace Into Operation

G27M furnaces are equipped with an electronic ignition system. Do not attempt to manually light burners on these furnaces. Each time the thermostat calls for heat, the burners will automatically light.
