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
z
Inspection and cleaning of the light oil filter cartdrige; replace it if necessary;
z
Check the overall condition of the flexible light oil hoses and make sure there are no signs of leakage;
z
check and clean the filter on the fuel pump: bilter 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;
z
disassemble, check and clean of the combustion head. When re-assembling carefully observe the measures quoted in Fig. 26;
z
check and clean the ignition electrodes and respective ceramic insulators: clean, adjust, and replace if necessary;
z
Disassemble and clean the light oil nozzles.
IMPORTANT: cleaning must be performed using solvent, not metal tools!
At the end of maintenance operations after first reassembling the burner, light the flame and check its shape, replacing the nozzle whe-
never a questionable flame shape appears. Whenever the burner is used intensely, we recommend preventively replacing the nozzle at
the start of each heating season;
z
Inspect and thoroughly clean the flame detection photoresistor and replace if necessary. In case of doubt, check the detection cur-
rent after first starting the burner by following the procedure shown on Fig. 27;
z
Clean and grease levers and rotating parts.
