FURNACE
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 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, 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. They may spark, which 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.
Operating Instructions
The furnace operates in the following manner: The wall thermostat sends a signal to the front roof air
conditioner circuit board, which closes a relay. Closing a relay sends an electrical signal to the furnace
to begin the 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 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 approximately two to three minutes after cool down.
Furnace Operation Requirements:
1. The LP-Gas primary valve on the LP-Gas tank is 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
cycled off.
