Operation; Using The Furnace - Holiday Navigator 2003 Owner's Manual

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 win-
dows 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.
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 or three minutes after cool down.
The furnace will operate when the following conditions have been met:
1. The LP-Gas primary valve on the LP tank is open and the LP-Gas valve
at furnace is on.
2. The house batteries in the motorhome are fully charged.
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.
• Slide the ON/OFF switch (on wall thermostat) to the ON position.
• Select the Furnace mode on the Comfort Control using the
MODE button.
• Select the desired temperature using the UP and DOWN arrow buttons.
NOTE: The furnace mode of the bedroom thermostat is non-
functional.
