THE FURNACE
HOW IT OPERATES
Use the wall mounted thermostat (Image 80.1) to turn the furnace on. Air is heated by
burning liquid propane (LP) gas. A blower using 12V power from the coach
battery(ies) circulates the hot air through the motorhome.
NOTE: If the chassis battery(ies) are not being charged via the chassis engine, a
campground connection or the generator, the furnace blower will will discharge the
power supply in about two to three hours and then the furnace will shut off.
If this happens, you may recharge the battery(ies) by running the chassis engine,
generator or campground connection. Charging by the chassis engine or the on-board
generator will replenish your battery(ies) to sufficient power in approximately forty five
minutes.
