This operation must be performed with the burner turned
off and mains power disconnected.
CLEANING THE FAN
9
Clean the inside and the rotor blades of the fan unit to remove
any build-up of dust. Accumulated dust reduces the air flow and
therefore reduces combustion efficiency, leading to increased
emissions.
9
Perform maintenance operations paying attention not to dam-
age or unbalance the fan during cleaning operations.
Proceed as follows
− remove the socket (1), the cable from the cable clamp (2), undo
the screws (3) and take out the air damper unit (4);
− clean the fan and the inside of the suction inlet, using a suit-
able brush and compressed air.;
− if necessary, gently remove the fan by undoing the screw (5).
