APPLIANCES AND SYSTEMS
2. Slide the Thermostat switch from Off to Heat
and press the Temp Selector button (up/down
arrows) until the desired temperature is shown
on the display.
3. The furnace fan should start to blow
immediately after setting the thermostat.
4. After approximately 30 seconds, the furnace
burner should light.
5. The furnace should now cycle off and on
automatically as the thermostat demands just
like a household furnace.
NOTE: If heat does not come out of the heat
ducts after a minute or so, the burner is
not lit.
Turn the thermostat off for 3-5 minutes,
ensure Propane Gas Tank valve is open
and tank is not empty, then repeat Steps
2-4.
If the furnace will not light after three
attempts, go to "Shut Down" steps and
contact your dealer or a local RV service
center for repair.
To Shut Down
1. Slide Thermostat switch to the Off position.
2. Close propane tank valve if coach will be
stored for a period of time.
Further Information
Refer to the manufacturer's user guide
provided in your InfoCase for further
information, including operating precautions,
and periodic maintenance. See "Coach
Maintenance Chart" in Section 11 - Maintenance
and Storage for recommended intervals.
NOTE: If the furnace burner has any residuals
of metal protectant or lubricants used
during manufacture of the furnace, it
may smoke slightly when the furnace is
used for the first time and may set off
your smoke alarm.
We recommend that you provide
adequate ventilation when using the
furnace for the first time to avoid a
nuisance smoke alarm.
We do not recommend removing the
smoke alarm battery.

HEAT PUMP

–If Equipped
Your coach may be equipped with an air
source Heat Pump built into the air conditioning
system. Because the Heat Pump operates on
electricity, it provides economical heat inside
your coach and helps reduce the use of propane
gas for heating in cooler weather.
A Heat Pump can be thought of as an air
conditioner running in reverse. An air
conditioner absorbs heat from the air on the
inside of the coach and moves it to the outside.
The Heat Pump does exactly the opposite. Even
cold air contains some heat, so a Heat Pump will
extract heat from the outside air on a cold day and
carry it to the inside of the coach to maintain a
comfortable temperature.
The efficiency of a Heat Pump decreases as
the outdoor air temperature drops, so
supplementary heat is often needed when the
outside temperature nears freezing. This system
is set to automatically start the propane furnace to
assist the Heat Pump if room temperature cools to
five degrees or more below the thermostat set
temperature. You may wish to manually switch
to furnace heat to maintain a higher temperature
when outside temperatures begin to reduce the
efficiency of the Heat Pump. The Heat Pump will
not operate when the outside temperature falls
below 36 degrees F.
To Operate the Heat Pump
Refer to the manufacturer's user guide
provided in your InfoCase for complete operating
instructions.
