FURNACE CONTINUED
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 flow or impede the
operation of the air circulation system should be removed.
For example, accumulated dust or lint could possibly obstruct the orifices for the pilot light or
may accumulate on the blower blades and unbalance the operation of the blower. Additionally
any debris in the duct work when heated by the furnace, could emit unpleasant odors or
possibly become a fire hazard.
The furnace system should be periodically cleaned. Annually is recommended unless the
motorhome is subjected to dust levels significantly greater than average. In this case more
frequent cleaning is recommended. The Owner's Information Package provides recommended
cleaning tips and procedures. When needed, a more thorough cleaning should be perfomred by
a qualified service technician.
WARNING:
NEVER attempt to modify the furnace. To do so may cause fire,
explosion, carbon monoxide poisoning or asphyxiation. If the furnace is
malfunctioning, immediately shut the unit "OFF" and contact a trained service
technician as soon as possible.
WARNING:
Be cautious when washing the exterior of the motorhome around the
furnace vent area. Water should never be sprayed directly into the furnace vent.
Should any water be forced beyond the rain baffles into the furnace vent, then the
surface may rust which in turn may cause improper combustion and produce
unwanted by products of combustion.
