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.
WARNING: All operations on the burner must be carried out with the mains disconnected!
ROUTINE MAINTENANCE OPERATIONS
Inspection and cleaning of the light oil filter cartridge. Replace if necessary.
Check the overall condition of the flexible light oil hoses and make sure there are no signs of leakage.
Inspection and cleaning of the filter inside the light oil pump.
Disassembly, inspection and cleaning of the combustion head. Respect the measurements listed in Fig. 18 carefully during
re-assembly.
Inspection and cleaning of ignition electrodes and respective ceramic insulators: clean, adjust, and replace if necessary
(see Fig. 18).
Disassemble and clean the light oil nozzle (see "DISASSEMBLY OF THE NOZZLE" on page 16).
Important: cleaning must be performed using solvent and not metal tools!
At the end of maintenance operations after first reassembling the burner, light the flame and check its shape, replacing the
nozzle whenever a questionable flame shape appears. Whenever the burner is used intensely, we recommend preventively
replacing the nozzle at the start of each heating season.
Inspect and thoroughly clean the flame detection photoresistor and replace if necessary. In case of doubt, check the detec-
tion current after first starting the burner by following the procedure illustrated in Fig. 23.
