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 fuel filter cartdrige, replace if necessary.
Check and clean the pilot gas filter cartdrige, replace if necessary.
Inspection and cleaning of the filter inside the light 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.
Dismantle, clean and check the combustion head (see Fig. 23).
Check and clean the ignition electrode on the pilot burner, adjustment and, if necessary, replacement (Fig. 25).
Check and clean the detection photoresistor, adjustment and, if necessary, replacement (page 32).
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.
Check the detection current (Fig. 26).
Clean and grease levers and rotating parts.
Maintenance of the pressure governor with filter (for ignitor gas train)
Before disassmbling the device, be sure that there is no pressurised gas inside it.
To check the filtering part (1) on threaded bodies (see picture):
remove the bottom cover, unscrewing the fixing screws;
remove the filtering part (1), clean it with water and soap, blow it with compressed air or replace it if necessary;
reassemble the filtering part in its initial position checking that it is placed in its own slots (see picture);
reassemble the bottom cover (3), being sure that the main bolt is centered in the bottom cover slot.
WARNING: ALL OPERATIONS ON THE BURNER MUST BE CARRIED OUT WITH THE MAINS DISCONNECTED AND
THE FUEL MANAUL CUTOFF VALVES CLOSED!
ATTENTION: READ CAREFULLY THE “WARNINGS” CHAPTER AT THE BEGINNIG OF THIS MANUAL..
