MAINTENANCE
WARNING: all work must only be done after first cutting power via the main switch and
after removing the plug. By removing the cover from the burner it is possible to carry
out the following checks and cleaning tasks.
PHOTORESISTOR
Remove and clean the sensor carefully. Use a clean, dry cloth. When replaced make
sure it is properly attached.
NOZZLE
Remove the high voltage wires on the transformer side and the photo-resistor, unscrew
the coupling and the other coupling on the fuel pump. Unscrew the cover attachment
screws and extract the nozzle holder set by rotating the cover anticlockwise. Remove
the high voltage wires on the electrodes, loosen the holder lock screw, remove the dif-
fuser/electrodes holder and then unscrew the nozzle. To clean the nozzle thoroughly
disassemble the filter and clean the slots and the spray hole with petrol. Never use
tools which might damage internal surfaces.
FUEL PUMP FILTER
Close the fuel aspiration gate, remove the pump cover, take out the mesh cartridge,
wash it with petrol and re-assemble carefully.
IGNITION ELECTRODES (4-5)
Clean the electrodes without varying their position with respect to the diffuser; if you
accidentally move them observe the dimensions given in fig. when re-assembling.
