14

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.

PERIODICAL SERVICING

z

Clean and examine the oil filter cartridge and replace it if necessary.

z

Examine the condition of the oil flexible hoses and check for possible leaks.

z

Clean and examine the filter inside the oil pump (see instructions in the Appendìx).

z

Dismantle, examine and clean the combustion head and when reassembling be carefully to respect the measures shown in
Tab. 5

z

Check the detection photocell, clean it and adjust the position if needed and, if necessary, replace it. If in doubt, check the
detection circuit after the burner has been restarted, following the diagram in Fig. 20.

WARNING: All operations on the burner must be carried out with the mains disconnected!

Correct position of electrodes and combustion 
head  (Fig. 19a e Fig. 19b)

z

Prepare a stable surface where lean the burner
during maintenance.

z

To gain access to the combustion head and to
the nozzles, slacken the screw on the blast tube
and remove it from the part that remains fixed to
the boiler.

z

To guarantee a good ignition, respect the mea-
sures indicated in Tab. 5.

z

Be sure to tight the screw that fix the electrodes
group, before reassembly the burner.

Check of the ionization current

See the diagram in Fig. 20 to measure the detection cur-
rent. If the signal doesn’t suit the suggested value, verify
the electric terminals, the cleaning of the combustion
head and the position of the photoelectric cell and
replace it if required
