FURNACE

1. All flue gas carrying areas external to the furnace (i.e.
chinmey, vent connector) are clear and free of obstructions.
2. The vent connector is in place, slopes upward and is
physically 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 ofthe furnace is sound without sagging
cracks, gaps, etc. around the base.
5. There are no obvious signs of deterioration of the furnace.

STARTING AND SHUTTING DOWN
YOUR FURNACE
FIRE AND EXPLOSION HAZARD
Failure to follow this warning could result in personal
injury/death or property damage.
Should the gas supply fail to shut off or if overheating
occurs, turn off the manual gas valve to the furnace
BEFORE turning off the electrical supply. (See Fig. 8.)
• 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 setting.
(See Fig. 7.)
2. Close the external manual gas valve. (See Fig. 8.)
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:
• 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 asuspected 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.
