4. Reinstall burner enclosure front.
5. If your furnace is free of the above conditions, replace
main furnace door and turn on electrical and gas supplies
to the furnace. (See Fig. 16, 17, and 18.)
6. Start the furnace and observe its operation. Watch the
burner flames to see if they are clear blue, almost transpar-
ent. (See Fig. 33.) If you observe a suspect malfunction,
or the burner flames are not clear blue, call your dealer.

HEADING SOUTH FOR THE WINTER?
DON’T FORGET YOUR FURNACE!
Since the furnace uses a condensing heat exchanger, some water
will accumulate in the unit as a result of the heat transfer process.
Therefore, once it has been operated, it cannot be turned off and
left off for an extended period of time when temperatures will
reach 32°F or lower unless winterized. Follow these procedures
to winterize your furnace:
1. Obtain propylene glycol (RV/swimming pool antifreeze
or equivalent).
2. Turn off electrical supply to the furnace. (See Fig. 20.)
3. Remove main furnace door. (See Fig. 23.)
4. Remove upper inducer housing drain connection cap.
(See Fig. 34.)

5. Connect field-supplied 1/2-in. ID tube to upper inducer
housing drain connection.
6. Insert field-supplied funnel into tube.
DANGER
If holes are found in the pipes or if any portion has
become disconnected, toxic fumes can escape
into your home. DO NOT OPERATE YOUR FUR-
NACE. Call your dealer for service.
CAUTION
If the furnace is installed in an unconditioned space
where the ambient temperatures may be 32°F or
lower, freeze protection measures must be taken.
CAUTION
Do not use ethylene glycol (Prestone II antifreeze
coolant or equivalent). Failure of plastic compo-
nents will occur.
