WARNINGS TO AVOID BURNOUT OR BAD COMBUSTION OF THE BURNER
– When the burner is stopped, the smoke pipe must be opened and effect a natural draught in the
combustion chamber. If the smoke pipe is closed, the burner must be drawn back till the extrac-
tion of blast tube from the furnace. Before operating in this way take the voltage off.
– The place, where the burner works, must have same openings suitable for the passage of air nec-
essary for combustion. To be sure about this, you have to control the smoke number of exhaust
gas with all the windows and doors closed.
– If in the place, where the burner works, there are air-breathings, check the existence of air-input
openings with dimensions suitable for the necessary air-exchange. In any case check that, when
the burner is stopped, the air-breathings do not draw warm smokes from pipes through the
burner.
– Turn the switch to position 1 before stopping the burner.
MAINTENANCE
The burner requires periodic maintenance carried out by a qualified and authorised technician in con-
formity with legislation and local standards.
Periodic maintenance is essential for the reliability of the burner, avoiding the excessive consump-
tion of fuel and consequent pollution.
Before carrying out any cleaning or control always first switch off the electrical supply to
the burner acting on the main switch of the system.
THE BASIC CHECKS ARE:
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.
Clean the filter in the oil suction line and in the pump.
Check for correct fuel consumption.
Check that the burner electrical connections are correct.
Replace the nozzle and check the correct position of electrodes.
Clean the combustion head in the fuel exit area.
Check that the positioning of the combustion head is correct and that it is properly fixed to the
boiler.
Check that the air damper is positioned correctly.
Let the burner run at full capacity for about ten minutes, setting all the elements correctly as explained in
this manual. Then carry out the analysis of the combustion by checking:
- Smoke index as per the Bacharach scale;
- NOx content (ppm);
- CO
percentage (%);
2
- Smoke temperature at the chimney.
