Freezing can result in severe damage to the plumbing components and the
Combi furnace. Damage due to freezing or an unsuitable winterizing fluid is
not covered by the manufacturer's warranty. Winterize the Combi furnace:
At the start of the winter season
Before traveling to a location where freezing conditions are likely.
If the furnace will be stored under freezing conditions or for an extended
period of time.
Winterizing the Plumbing System
Preparing your recreation vehicle for colder weather or storage is very important for most
states and Canada. Failure to prepare your RV may cause water supply lines and the water
heater to freeze. The RV should be winterized at the end of the camping season or when it
will be exposed to temperatures that will fall at or below 32°F (0°C). Repairs due to freezing
are not covered by warranty.
™ NOTE: The winterization process may vary slightly due to different plumb-
ing configurations between models.
™ NOTE: Appliances must be winterized. Refer to the manufacturer's manual
for possible additional information or contact Customer Service for assis-
tance.
