Heading South For The Winter - Payne PG9MAA User's Information Manual

2. Remove burner enclosure front. (See Fig. 33 or 34.)
NOTE: It will be necessary to remove five screws.
Inspect the gas burners and ignitor area for dirt, soot, rust, or scale.
!
CAUTION: If dirt, rust, soot, or scale accumulations are found, call your dealer. Do not operate your furnace.
3. Inspect the combustion-air and vent pipes for sags, holes, cracks, or disconnections.
!
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 FURNACE. Call your dealer for service.
4. Reinstall burner enclosure front with five screws.
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. 14, 15, and 16.)
6. Start your furnace and observe its operation. Watch the burner flames (with main furnace door off) to see if they are clear
blue, almost transparent. (See Fig. 35.) 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!
!
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.
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).
!
CAUTION: Do not use ethylene glycol (Prestone II antifreeze coolant or equivalent). Failure of plastic com-
ponents will occur.
2. Turn off electrical supply to your furnace. (See Fig. 23.)
3. Remove main furnace door. (See Fig. 24.)
4. Remove upper inducer housing drain connection cap. (See Fig. 36.)
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. 37.)
8. Remove funnel and tube from inducer housing and replace drain connection cap and clamp.
9. Replace main furnace door. (See Fig. 31.)
