CARBON MONOXIDE POISONING HAZARD
Failure to follow this warning could result in personal
injury or death.
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.
! WARNING
Check the combustion--air intake and vent pipe on the outside of
your home for blockage.
When dirt, soot, scale, or rust is allowed to build up, your furnace
can suffer a loss of efficiency and perform improperly.
Accumulations on the main burners can result in firing out of
normal sequence. This delayed ignition creates an alarmingly
loud sound.
UNIT OPERATION HAZARD
Failure to follow this caution may result in property
damage.
If your furnace makes an especially loud noise when the
main burners light, shut down your furnace and call your
dealer.
CAUTION
!
To inspect the combustion area and vent system, you will need
a flashlight. Refer to Fig. 3 and proceed as follows:
1. Turn off the gas and electrical supplies to the furnace and
remove the main furnace door. (See Fig. 8, 9, and 10.)
2. Remove burner enclosure front. (See Fig. 33.)
Inspect the gas burners, igniter area, and remainder of furnace for
dirt, rust, soot, or scale.
CARBON MONOXIDE POISONING HAZARD
Failure to follow this warning could result in personal
injury or death.
If dirt, rust, soot, or scale accumulations are found, call
your dealer. Do not operate your furnace.
! WARNING
3. Inspect the combustion--air and vent PVC pipes for sags,
holes, cracks, water leaks, blockage or disconnections.
Horizontal portions of pipes 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. 13, 14, and 15.)
6. Start the furnace and observe its operation. Watch the
burner flames to see if they are clear blue, almost
transparent. (See Fig. 34.) 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!
UNIT AND PROPERTY DAMAGE HAZARD
Failure to follow this caution may result in damage to the
furnace and other property damage.
If the furnace is installed in an unconditioned space where
the ambient temperatures may be 32_F (0_C) or lower,
freeze protection measures must be taken to prevent minor
property or product damage.
CAUTION
!
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 (0_C) or lower unless winterized. Follow these
procedures to winterize your furnace:
1. Obtain propylene glycol (RV/swimming pool antifreeze or
equivalent).
UNIT COMPONENT DAMAGE HAZARD
Failure to follow this caution may result in damage to the
furnace and other property damage.
Do not use ethylene glycol (Prestone II antifreeze coolant or
equivalent). Failure of plastic components may occur.
