4. If your furnace is free of the above conditions, turn on gas
and electrical supplies to the furnace. (See Figure 15
and Figure 16)
CARBON MONOXIDE POISONING HAZARD
Failure to follow this warning could result in personal
injury or death.
If holes are found or if the vent pipe is obstructed or is
not connected, toxic fumes can escape into your home.
DO NOT OPERATE YOUR FURNACE. Call your dealer
for service.

WARNING
5. Restore electrical power to the furnace.
6. Start the furnace and observe its operation. If possible,
watch the burner flames. Are they burning bright blue? If
not or if you suspect some other malfunction, call your
servicing dealer.
7. Replace the access door. (See Figure 14)
WINTERIZATION
!
CAUTION
UNIT AND PROPERTY OPERATION HAZARD
Failure to follow this caution may result in unit component or
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
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 (Automotive antifreeze coolant
or equivalent). Failure of plastic components may occur.
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).
ELECTRICAL SHOCK HAZARD
Failure to follow this warning could result in personal
injury or death.
Turn off electrical power supply to your furnace before
removing the access doors to service or perform
maintenance.
!
WARNING
2. Turn off gas and electrical supplies to your furnace. See
Figure 9 and Figure 10.
3. Remove furnace control compartment door. See
Figure 11.
4. Remove one of the unused rubber plugs in the port on
the collector box opposite the condensate trap. See
Figure 17.
5. Connect a field supplied 3/8-in. (9.5-mm) ID tube to the
open port on the collector box. See Figure 17.
Figure 17 Antifreeze into Funnel/Tube
L11F065
Representative drawing only, some models may vary in appearance.
6. Insert a field supplied funnel into the tube.
7. Pour one (1) quart of antifreeze solution into the
funnel/tube. Antifreeze should run through the inducer
housing, overfill condensate trap and flow to an open
drain.
8. If a condensate pump is used, check with pump
manufacturer to verify pump is safe for use with
antifreeze used. Allow pump to start and pump antifreeze
to open drain.
9. Remove funnel and tube from collector box.
10. Replace plug in collector box.
11. Remove other plug and repeat steps 4 through 10.
12. Replace main door. See Figure 14.
13. When furnace is re-started, flush condensate pump with
clear water to check for proper operation before
re-starting furnace.
14. Antifreeze need not be removed before re-starting
furnace.
