NEPTUNE 2004
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. When the blower motor attains
a predetermined speed it will close the air prover or sail switch. The sail switch
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 about two or
three minutes after cool down.
The furnace will operate when the
following conditions have been met:
• The primary LP-Gas valve on the
LP-Gas tank is open and the LP-Gas
valve at the furnace is on.
• The house batteries in the motorhome
are charged.
• The battery cut-off switch at the entry
door must be ON.
Using the Furnace:
• Set the SYSTEM switch to FURNACE.
• Set the FAN switch to AUTO.
• Set desired temperature.
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 diag-
nosed and repaired before resuming operation.
CAUTION: Do not store any items or materials in the furnace area.
Restricted air flow may hamper furnace operation leading to failure
and/or fire hazard.
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.
NOTE: When washing the exterior of the motorhome, avoid a direct
stream of water into the outside furnace vents. This can damage the
furnace.
