At least once a year carry out the maintenance operations listed below. In the case of seasonal servicing, it is recommended to carry
out the maintenance at the end of each heating season; in the case of continuous operation the maintenance is carried out every 6
months.
ROUTINE MAINTENANCE
Check and clean the oil filter cartdrige, replace if necessary.
Check and clean the filter inside the oil pump: filter must be thoroughly cleaned at least once in a season to ensure correct working
of the fuel unit. To remove the filter, unscrew the four screws on the cover. When reassemble, make sure that the filter is mounted
with the feet toward the pump body. If the gasket between cover and pump housing should be damaged, it must be replaced. An
external filter should always be installed in the suction line upstream of the fuel unit.
Check the fuel hoses for possible leaks.
Remove, clean and check the combustion head (see Fig. 14).
Check and clean the ignition electrodes, adjust and, if necessary, replace (Fig. 16).
Check and clean the detection photoresistor, adjust and, if necessary, replace it (Fig. 18).
Remove and clean the fuel nozzle
(Important:
cleaning must be performed using solvent, not metal tools!
).
At the end of
maintenance operations after the burner reassembly, light the flame and check its shape, replacing the nozzle whenever a questio-
nable flame shape appears. Whenever the burner is used intensely, we recommend preventively replacing the nozzle at the start of
each heating season.
Clean and grease levers and rotating parts.
IMPORTANT:Remove the combustion head before checking the ignition electrodes.
Oil filter maintenance

1
shut off fuel in the line section being serviced;
2
