MAINTENANCE OF MOTORS
Always disconnect the appliance from the main power supply and allow it to
cool before any servicing operation. The motor used on the flame blower is pre-
lubricated for extended bearing life and requires no further lubrication. However,
periodic cleaning/vacuuming of the appliance around the air intake and exhaust,
as well as the blower 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 blower for free movement and for debris restricting air flow.
If the blower does not move freely, the unit must be turned off and the blower
replaced immediately in order to prevent further damage to the unit.
WARNING : Make sure all power to the appliance is turned OFF
before proceeding.
