FURNACE
The furnace and its related components are 12 Volt DC operated and use LP-Gas as the fuel source. Electronic
circuitry (automatic ignition) is used to ignite the burner. The furnace uses outside air for the burner combustion,
and exhaust is expelled through the outside vent. Inside air is drawn into the furnace and blown across the internal
heat exchanger. Heated air is then discharged through ducted hoses which can be run throughout the motorhome.
CAUTION:
Do not store any items/materials in furnace area. Restricted air flow may hamper furnace
operation leading to failure and/or fire hazard.
WARNING:
IF YOU SMELL GAS extinguish all open flames and turn off the main gas supply. Liquid
propane is a highly volatile, extremely dangerous gas. It can explode or ignite, resulting in
property damage, injury or death. Propane is heavy and can float on the floor or hide in
corners. Open all windows and doors. Do not touch electrical switches, which can spark and
ignite. Keep all open flames, spark producing devices and smoking material out of the area.
Contact a qualified service center to have the problem correctly diagnosed and repaired
before resuming operation.
Operating Instructions
When the furnace is selected there is a small time delay before the blower motor begins. After the temperature
on the thermostat is reached the burner is extinguished. The blower motor stops approximately two to three
minutes after cool down.
Furnace Operation Requirements:
1. The LP-Gas primary valve on the LP tank and the electric LP-Gas valve at the remote fi ll are open.
2. The house batteries in the motorhome are fully charged and the interior house power is on.
NOTE:
The automatic ignition circuit board will attempt to light the burner three times before the
ignition board will go into lock-out. If the burner does not light, the furnace blower motor
will continue to run and the wall thermostat will have to be turned off.
Tips:
• After storage the furnace may produce a musty
smell during the fi rst couple of cycles.
• Operating the furnace at an altitude above 5,000
feet reduces the BTU output due to air/fuel ratio.
• The furnace will periodically need servicing by a
qualifi ed technician. If the furnace exhibits unusual
symptoms or noises, or has an unusual odor when
operating, have the furnace checked or serviced.
• If the blower fails to operate after verifying the
batteries are charged and fuses are good, use a coin
or screwdriver to open outside access door. Ensure
the Reset switch is in the Reset position.
