TURNING THE FURNACE ON
1. Ensure the motorhome’s 12 volts DC electrical system
is ON by turning on the Master Battery Disconnect
Switch, connecting to shore power or operating the
generator.
2. Turn ON LP gas supply at the propane tank.
Counterclockwise rotation opens the valve; clockwise
rotation closes the valve.
3. Check that power to the furnace is ON at the main
power distribution panel.
4. Set the thermostat selector switch to HEAT.
5. Set the desired temperature on the thermostat. e
furnace should automatically come on if the tem-
perature setting on the thermostat is higher than the
ambient air temperature.
TURNING THE FURNACE OFF
• Reduce the temperature setting on the thermostat to
its minimum level.
• Set the selector switch on the thermostat to OFF.
• If you are preparing to travel, turn OFF the LP gas
supply at the tank.
NOTE:
• During the initial operation of the furnace, you may
detect slight fumes caused from the burning of
residue and oils left from the manufacturing pro-
cess. This is a normal occurrence and these fumes
should subside within several minutes
• If the outside temperature will drop below 32° F
(0° C) AND your motorhome is remaining parked,
AND is not winterized, allow the furnace to operate
in order to prevent the possibility of on-board water
freezing and causing damage to the motorhome’s
water system.
• For additional information regarding heating and
cooling systems installed on your motorhome,
please refer to the TMC HVAC System Guide
and the HVAC manufacturer’s product information
available through the TMC on-line Owners Re-
source Document Service:

Furnace Care and Maintenance
Listed here are several safety related instructions that you,
the owner, should follow each heating season to assure
continued safe operation of the furnace. A periodic inspec-
tion of the furnace by a qualied service technician is also
recommended.
The combustion of any hydrocarbon-based fuel
creates carbon monoxide (CO) gas, which is extremely
poisonous to humans and pets. Carbon monoxide gas
is tasteless and odorless!
• Inspect furnace burners annually for proper
combustion. Inspect for holes or cracks in
combustion chambers, that if exist, could allow
carbon monoxide gas into living space of the
motorhome.
• Inspect propane (LP) system annually for cracks,
leaks and worn components.
• Repair or replace faulty furnace and/or propane
(LP) system components promptly.
• Do not block or restrict furnace air intakes and/or
exhausts.
• Test the LP/CO detector regularly to ensure proper
operation.
• Know and practice evacuation procedures if LP
and/or CO gas is detected.
DANGERDANGER
DO NOT use this appliance of any part has been
under water. A ood-damaged furnace is extremely
dangerous. Attempts to use the furnace can result in
re or explosion.
A qualied service technician should be contacted to
inspect the furnace and to replace all gas controls,
control system parts, electrical parts that have been
wet or replace the entire furnace, if deemed necessary.
ROAD VIBRATION CAN LOOSEN PROPANE FITTINGS.
It is important to check the Propane System for leaks at
least every 5,000 miles, and whenever the tank is lled.
It is also recommended to have the entire Propane
System checked annually by a qualied propane
service technician.
DO NOT install screens over the intake air or exhaust
vents for any reason. Screens will become restricted
and cause unsafe furnace operation.
For your safety, only factory authorized parts are to be
used on your furnace and venting system.
