Starting and Shutting Down Your Furnace

!WARNING

FIRE OR EXPLOSION HAZARD

Failure to follow this warning could result in fire, personal injury/death or property damage.

Do not keep combustible materials, gasoline, and other flammable liquids or vapors around your furnace.

STARTING AND SHUTTING DOWN YOUR FURNACE

Instead of a continuously burning pilot ﬂame which wastes valuable energy, your furnace uses an automatic, hot surface ignition system to light the burners each time the thermostat starts your furnace. Follow these important safeguards:

!WARNING

FIRE AND UNIT OPERATION HAZARD

Failure to follow this warning could result in fire, personal injury/death or property damage.

For proper and safe operation the furnace needs air for combustion and ventilation. Do not block or obstruct the openings on the furnace, air openings to the area in which the furnace is in- stalled, and the space around the furnace.

Examine the furnace installation monthly to determine that:

1.All ﬂue gas carrying areas external to the furnace (i.e. chimney, vent connector) are clear and free of obstructions.

2.The vent connector is in place, slopes upward and is phys- ically sound without holes or excessive corrosion.

3.The return-air duct connection(s) is physically sound, is sealed to the furnace casing, and terminates outside the space containing the furnace.

4.The physical support of the furnace is sound without sag- ging cracks, gaps, etc. around the base.

5.There are no obvious signs of deterioration of the furnace.

6.The burner ﬂames are in good adjustment. (See Fig. 8.)

•Never attempt to manually light the burners with a match or other source of ﬂame.

•Read and follow the operating instructions on inside of main furnace door, especially the item that reads as follows:

Wait 5 minutes to clear out any gas. Then smell for gas, including near the ﬂoor. If you smell gas, STOP! Follow “B’’ in the safety information above on this furnace label. If you don’t smell gas, go to the next step.

•If a suspected malfunction occurs with your gas control system, such as the burners do not light when they should, refer to the shutdown procedures on inside of main furnace door, or in the “Shutting Down Your Furnace” section and call your dealer as soon as possible.

! WARNING

FIRE HAZARD

Failure to follow this warning could result in a fire or explosion, and personal injury/death or prop- erty damage.

Should the gas supply fail to shut off or if over- heating occurs, turn off the manual gas valve to the furnace BEFORE turning off the electrical sup- ply. (See Fig. 11.)

•CHECK AIR FILTER: Before attempting to start your furnace, be sure the furnace ﬁlter is clean and in place. See “Performing Routine Maintenance” section in this manual. Then proceed as follows:

STEPS FOR STARTING YOUR FURNACE

1.Set your room thermostat to the lowest temperature set- ting. (See Fig. 10.)

2.Close the external manual gas valve. (See Fig. 11.)
