3. Inspect the combustion-air and vent PVC pipes for sags,
holes, cracks, or disconnections. Horizontal portions of
vent pipe must slope downward toward furnace.

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. 12, 13, and 14.)
6. Start the furnace and observe its operation. Watch the
burner flames to see if they are clear blue, almost transpar-
ent. (See Fig. 28.) If you observe a suspected 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. 16.)
3. Remove main furnace door. (See Fig. 18.)
4. Remove upper right inducer housing drain connection
cap. (See Fig. 29.)

5. Connect field-supplied 1/2-in. ID tube to upper inducer
housing drain connection.
6. Insert field-supplied funnel into tube.
7. Pour 1 quart of antifreeze into funnel/tube. Antifreeze
should run through inducer housing, overfill condensate
trap, and flow into open field drain. (See Fig. 30.)
8. Remove funnel and tube from inducer housing and
replace drain connection cap and clamp.
9. Replace main furnace door. (See Fig. 25.)
10. Propylene glycol need not be removed before restarting
furnace.
A CHECK-UP CHECKLIST
Your furnace represents an important investment in your fami-
ly’s comfort and your home’s value. To keep it performing
properly and to prevent future problems, have a trained service
specialist give your furnace a professional check-up annually.
The following checklist can be used as a guideline to proper
service:
CAUTION
If dirt, rust, soot, or scale accumulations are found,
call your dealer. Do not operate your furnace. Failure
to follow this caution would result in minor property
or product damage.
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 to
prevent minor property or product damage.

Do not use ethylene glycol (Prestone II antifreeze
coolant or equivalent). Failure of plastic compo-
nents will occur.
