ServicingExcept for installation and cleaning described in this manual, an authorized service representative should perform any other servicing.

! NOTE: The heater should not be operated with an accumulation of dust or dirt on or in the unit, as this can cause a build up of heat and eventual damage. For this reason the heater must be inspected regularly, depending upon conditions and at least at yearly intervals.
