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.)

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:
• 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.
•
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.)
