Maintenance
Periodically remove and clean return air filter. Filter is located above removable panel in air box .Wash
filters with soap and warm water and to air dry. Never run without filter.
Remove and clean air box housing with mild detergent. Never use
furniture polish or scouring powders.
Mounting Bolts:
The AC mounting bolts should be re-torqued every six months. Four
bolts are located behind the return air filter. Torque the mounting bolts to
approximately 40 to 50 in. lbs. The base gasket should be compressed to
approximately ½".
AC Cover Screws:
Use a screwdriver to ensure the AC cover screws are tight whenever the
roof is accessed.
fUrnace
The furnace is 12 Volt DC operated and uses propane as the fuel source. Electronic circuitry (automatic
ignition) ignites the burner. The furnace uses outside air for burner combustion. 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 that run throughout the recreational vehicle. Warm air is also directed to heat the
holding tanks in the recreational vehicle.
Operation
The furnace is directly controlled by a wall thermostat that sends a signal to the roof air conditioner. The air
conditioner then sends an electrical signal to the furnace to begin ignition cycle. There is a small time delay
before the blower motor begins. Once the furnace 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 propane valve
closes and extinguishes the burner. The blower motor stops after a two or three minute cool down period.
INFORMATION:
See the furnace OEM manual for complete operation
information.
To Operate the Furnace:
1. The valve on the propane tank is open.
2. The house battery is charged and on.
Wall Thermostat
Switch thermosat to Heat.
Set thermostat to desired temperature.
WARNING:
IF A PROPANE SMELL exists, extinguish all open flames and turn off the main propane supply.
Propane is an extremely dangerous gas that can ignite and explode, 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 as they may spark. Keep open flame, 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.
