APPLIANCES & SYSTEMS
2. Move THERMOSTAT switch from Off to
Heat and press the Temp Selector button (Up/
Down arrows) until the desired temperature is
shown in the display.
3. Furnace fan should start to blow immediately
after setting the thermostat.
4. After about 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 thermostat off for 3-5 minutes,
check to be sure propane gas tank valve
is open and tank is not empty, then try
steps 2-4 again.
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 Off position.
2. Close propane tank valve if coach will be
stored for a period of time.
For Further Information
Please see the furnace operating instructions
provided in your InfoCase for further
information, including operating precautions,
and periodic maintenance. See the Coach
Maintenance Schedule 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
4-8
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 gas furnace to assist the
heat pump if room temperature cools to 5 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:
See the air conditioning/heat pump
manufacturer's information in your InfoCase for
complete operating instructions.
