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 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 of the furnace
is sound without sagging cracks,
gaps, etc. around the base.
5. There are no obvious signs of dete-
rioration of the furnace.
6. The burner flames are in good
adjustment. (See Fig. 8.)

WARNING
FIRE AND UNIT OPERATION
HAZARD
Failure to follow this warning
could result in fire, personal in-
jury/death or property damage.
For proper and safe operation
the furnace needs air for com-
bustion and ventilation. Do not
block or obstruct the openings
on the furnace, air openings to
the area in which the furnace is
installed, and the space
around the 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:
• 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 not lighting when they
should, refer to the shutdown proce-
dures on inside of main furnace door,
or in the “Shutting Down Your Fur-
nace” section and call your dealer as
soon as possible.
CHECK AIR FILTER: Before
attempting to start your furnace, be
sure the furnace air filter is clean and
in place. See “Performing Routine
