HEATING & AIR CONDITIONING
FURNACE
The Wayfarer is equipped with a forced-air furnace fuel 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 off” of
manufacturing compounds or residues left on the heat 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.
On a regular basis, thoroughly clean the complete furnace and air-tube passageways to remove dust,
lint, and any other possible obstructions. Leak-test the entire LP gas system at least annually. Also check
and clean the air-blower system annually.
Any access hatches to the furnace are for authorized service personnel only, as there are no user
serviceable parts on the furnace. Accordingly, do not attempt to tamper with the interior of the furnace.
