Tiffin Motorhomes WAYFARER 2021, Owner'S Manual

FURNACE
The Wayfarer is equipped with a forced air furnace system fueled by propane (LP) gas. The
furnace is controlled by the wall mounted thermostats located inside the motorhome. (Figure
33.1) . These thermostats control both the heating and air conditioning for the motorhome.
In the gas heating mode the furnace heats the air which in turn is circulated through the duct
work 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 from
blocking the warm air return.
NOTE: When a furnace is being used for a first time, there may be an initial "burn
off" of manufacturing compounds or residue that is left on the heat exchange or
duct work. These can produce odors, fumes and possibly some smoke. This is
normal and should not cause concern unless it persists for an excessive amount of
time.
To minimize the after effects of this "burn off" process, the initial use of the furnace should be
done with all of the doors and windows open to permit normal air circulation and to dissipate
these odors and fumes.
(NOTE: If the "burn off" process causes the smoke or propane (LP)
alarms to set off an audible alarm, continue the venting process until the alarms reset).
For routine operation of the furnace, set the thermostat to the desired temperature setting and
then set the thermostat to gas heat. In about one minute, the furnace should begin to operate
and warm or hot air should be coming through the duct work.
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. (NOTE: This procedure 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 propane (LP) gas system at
the minimum of at east annually. Also have the air blower system checked and cleaned
annually.
(NOTE: These tasks should be done by a certified qualified technician).
(NOTE: Any access hatches to the furnace are for authorized service personnel only. There
are no user serviceable parts on the furnace. Accordingly, do not attempt to tamper with or
alter the interior of the furnace in any way).
