The furnace and its related components are 12 Volt DC operated, using 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 ducked hoses which can be run throughout the recreational
vehicle. The warm air is used to heat the holding tank in the recreational vehicle.
Operation
The furnace operates with a hand held remote control that sends a signal to the front roof air conditioner. The
air conditioner sends an electrical signal to the furnace to begin ignition cycle. There is a small time delay before
the blower motor begins. Once the blower motor attains a predetermined speed it will close the air prover or sail
switch. The sail switch, which is now closed, sends the electrical signal through a high temperature protection
switch, then to the automatic ignition circuit board. After the thermostat is satisfied the gas valve closes and
extinguishes the burner. The blower motor stops about two or three minutes after cool down.
The furnace will operate when the following conditions have been met:
1. The LP-Gas valve on the LP tank is open and the LP-Gas valve at the furnace is on.
2. The house battery is charged.
WARNING:
IF A GAS SMELL exists, extinguish all open flames and turn off the main gas supply.
Liquid propane is an extremely dangerous gas. It can explode or ignite, which may result
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, as they may spark
and can 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.
CAUTION:
Do not store any items or materials in the furnace area. Restricted air flow may hamper
furnace operation leading to failure and/or fire hazard.
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 hand held remote will have to be cycled off.
NOTE:
When washing the recreational vehicle exterior, avoid a direct stream of water into the
outside furnace vents. This can damage the furnace.
• After the recreational vehicle has been removed from storage, operation of the furnace may produce a
musty smell during the first couple of cycles.
• Operating the furnace at altitudes above 5,000’ reduces the BTU output due to air/fuel ratio.
• The furnace must be periodically serviced by a qualified technician. If the furnace exhibits unusual
symptoms or noises, or has an unusual odor when operating, have the furnace checked and/or serviced.
