MAINTENANCE

Disconnect the electric supply to the burner by switching off the main power switch and close the light
oil shut-off valve before maintaining or checking the system.
The burner requires scheduled maintenance that must be carried out by qualified personnel and in compliance
with local legislation.
Scheduled maintenance is vital for the smooth operation of the burner; it avoids waste of fuel and reduces harm-
ful emissions into the atmosphere.
THE FUNDAMENTAL OPERATIONS TO CARRY OUT ARE AS FOLLOWS:
Check there are no occlusions or obstructions in the inlet or return pipes, in the air suction areas and in the
combustion product waste pipe.
Check that the positioning of the combustion head is correct and that it is properly fixed to the boiler.
Clean the combustion head at the fuel outlet.
Clean the fuel suction line filter and the pump filter.
Check that the burner electrical connections are correct.
Clean the flame detector.
Check for correct fuel consumption.
Check the combustion head (fig. 14 page 8) and the air damper are set correctly (fig. 14 page 8).
Replace the nozzle if necessary (fig. 14 page 8) and check the correct position of electrodes (fig. 11-12 page 7).
Clean the fan.
Leave the burner working without interruptions for 10 min. and check the right settings at 1
of all components stated in this manual.
Then carry out the analysis of the combustion by checking:
Smoke index as per the Bacharach scale;
CO percentage (%);
2
CO content (ppm);
NOx content (ppm);
Smoke temperature at the chimney.
