Maintenance of Motors
Always disconnect the appliance from the main power supply and allow it to cool before any servicing operation.
The motors used on the fan heater and flame blower are pre-lubricated for extended bearing life and require no further
lubrication. However, periodic cleaning/vacuuming of the appliance around the air intake and exhaust, as well as the fan
heater is recommended. For heavy or continuous use, periodic cleaning must be done more frequently. If the heater
blows alternating cold and warm air, check the fan for free movement and for debris restricting air flow. If the fan does
not move freely, the unit must be turned off and the fan replaced immediately in order to prevent further damage
to the unit.
WARNING: Make sure the power is turned OFF before proceeding.
