WARNING

Any unfamiliar smell can alert you to presence of gas or aldehydes. If you detect any unfamiliar odor follow instruction in Section 4.B.1. Otherwise, nausea, asphyxiation or fire could occur resulting in damage, injury or death.

WARNING

Do not block or cover combustion openings in the furnace door or closet door. Blocking or covering these openings could cause nausea, asphyxiation or fire resulting in damage, injury or death.

WARNING

Do not block or cover any openings from outside the furnace area which supply combustion and ventilation air to your furnace. Keep insulation away form these openings. Blocking or covering these openings could cause nausea, asphyxiation or fire resulting in damage, injury or death.

WARNING

Aloud noise may mean faulty burner ignition. If your furnace makes a loud noise, turn it off. Follow instructions in Section 4.B.2. If you don’t turn off your furnace, it could cause fire or an explosion resulting in damage, injury or death.

WARNING

If your furnace is in an attic or other insulated space, keep all insulating materials at least 12 inches away from its burner combustion air openings. Block or covering these openings could cause nausea, asphyxiation or fire resulting in damage, injury or death. Examine furnace area when the furnace is installed or when insulation is added to that area. Insulation materials may be combustible.

WARNING

Do not operate furnace with blower door open or removed. Do not alter furnace to allow operation with blower door removed. Doing either could allow combustion products to circulate throughout the furnace area causing nausea, asphyxiation or fire resulting in damage, injury or death.

WARNING

Front door must be in place during furnace operation. Hot surfaces behind front door.

2.2STORAGE AND USE OF FLAMMABLE, CORROSIVE AND COMBUSTIBLE PRODUCTS NEAR YOUR FURNACE

WARNING

Never store or use flammable liquids or vapors near or on your furnace. These include gasoline, kerosene, cigarette lighter fluid, cleaning fluids, solvents, paint thinners or painting compounds. Flammable vapors can travel great distances before igniting.

WARNING

Never store or use anything near or on your furnace that can produce vapors that are corrosive to gas-fired furnaces. Vapors from products containing chlorines, fluorines, bromines and iodines can cause vent system or heat exchanger failure. Examples of such products are spray or aerosol containers, detergents, bleaches, cat litter, waxes, adhesives, solvents and other cleaning compounds. Vent system or heat exchanger failure could cause nausea, asphyxiation or fire resulting in damage, injury or death.
