HEATING AND AIR CONDITIONING
FURNANCE
The Wayfarer is equipped with a forced-air furnace fueled by LP gas. The
furnace is controlled by the wall-mounted thermostats (Figure 3-1)
located inside the motorhome. These thermostats control both the
heating and air conditioning for the motorhome.
In the gas heating mode, the furnace heats air which, in turn, is
circulated through ductwork in the floor of the motorhome. If any
obstruction(s) block the floor vent(s) or air-return register, then the
furnace will not function properly. Any items stored under the cabinets
should be carefully stowed to prevent damaging or crushing the furnace
ducting or blocking the warm-air return.
When a furnace is being used for the first time, there may be an initial
“burn-off” of manufacturing compounds or residues left on the heat
exchanger or in the ductwork which could produce odors, fumes, and
possibly some smoke. This is normal and should not cause concern,
unless it persists for an excessive amount of time. Figure 3-1: Thermostat
To minimize the after-effects of this “burn-off” process, the initial use of the furnace should be done
with all the doors and windows open to permit normal air circulation to dissipate these odors and
fumes.
For routine operation of the furnace, set the thermostat to the desired temperature setting and then
turn the thermostat to gas heat. In about a minute, the furnace should begin to operate and warm or
hot air should be coming through the ductwork.
To shut down the furnace, turn the thermostat to the “off” position. Even though the thermostat may
be turned “off,” the furnace system will continue to run for about a minute or so to permit a gradual
cool-down of the heating system which is normal.
