months.
ROUTINE MAINTENANCE
Check and clean the cartdrige of the fuel filter, replace it if necessary (see next paragraph);
carefully check the fuel flexible hoses for leaks;
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;
remove, check and clean the combustion head;
check the ignition electrodes and their ceramic insulators, clean, adjust and replace if necessary;
remove and clean the oil nozzles (IMPORTANT: do not clean the nozzles using metallic or sharp utensils, use only solvents or
steam); at the end of maintenance operations, refit the burner, turn it on and check the combustion. If in doubt, replace the defec-
tive nozzle/s. In case of intensive use of the burner, the nozzles must be replaced at the end of the working season;
check and carefully clean the flame detection photoresistor, if necessary replace it and, if in doubt, check the detection current fol-
lowing the diagram on the manual;
clean and grease levers and rotating parts.
