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 fur-
nace 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 fur-
nace 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 opera-
tion.
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 approxi-
mately 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 fill
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 fur-
nace blower motor will continue to run and the wall thermostat will have to be cycled
off.
