HEATING & AIR CONDITIONING
To shut down the furnace, turn the thermostat to the “o ff ” position. Even though the thermostat may
be turned “o ff ,” 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-ser-
viceable parts on the furnace. Accordingly, do not attempt to tamper with the interior of the furnace.
NOTICE
Be cautious when washing the exterior of the motorhome. Water should
never be sprayed directly into the furnace vent. Should any water be forced
beyond the rain baffles into the furnace vent, the furnace may rust which, in
turn, may cause improper combustion and produce unwanted by-products
of combustion.
Before the beginning of each travel season, the furnace should be thoroughly cleaned and inspected.
Any obstructions, debris, or lint which may obstruct free air fl ow or impede the operation of the air-cir-
culation system should be removed. For example, accumulated dust or lint could possibly obstruct the
ori fi ces for the pilot light or may accumulate on the blower blades and unbalance the operation of the
blower. Additionally, any debris in the ductwork, when heated by the furnace, could emit unpleasant
odors or possibly become a fi re hazard.
Th e furnace system should be periodically cleaned. Annually is recommended unless the motorhome is
subjected to dust levels signi fi cantly greater than average, in which case more frequent cleaning is rec-
ommended. Th e Owner’s Information Package provides recommended cleaning tips and procedures.
When needed, a more thorough cleaning should be performed by a quali fi ed service technician.
