S5 Removing or Cleaning Fan
As part of regular service procedure, it is recommended that the fan is removed for cleaning. Dust will
build up on the fan rotor and in the cavity where the fan is located. This can be removed by the service
person using a hearth brush and a vacuum cleaner.
ISOLATE THE POWER AND GAS SUPPLY TO THE FIRE BEFORE COMMENCING THIS
PROCEDURE.
Remove the electronic tray located on the base of the chassis (instructions provided in the next
section) before attempting to remove the room air fan. Disconnect the 3-way fan connector and
remove the two screws circled in the diagram below (the DF960 and DF990 requires the LH access
hatch to be removed in order to get to the LH screw) . The room air fan can now be pull towards you
and removed through the burner tray hole.
