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.

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 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 the return air from a room where another gas appliance (ie., a water heater) is installed. Even though this furnace draws its combus- tion air from outside of the structure, other gas ap- pliances 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 distributed 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 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
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
