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.
