TYPE OF MALFUNCTION POSSIBLE CAUSE SOLUTION
Defective flame, pulsating or de-
taching from the combustion orifice
1) Excessive draught (only if there is a chimney
fan)
2) Pre-heating temperature unsuitable for the
type of fuel oil employed
3) Dirty or worn nozzle
4) Water in the fuel
5) Dirty disk
6) Too much combustion air
7) Air passage between disk and head too
closed
1) Modify pulley diameters to change fan speed
2) Increase or decrease it
3) Clean or replace it
4) Drain it from the pre-heating tank and rough-
ing filter through the dedicated plugs. If
necessary, drain it also from the tank using
a suitable pump. (Never use the burner pump
for this job)
5) Clean it
6) Reduce the amount of combustion air
7) Correct the position of the combustion head
regulating device
Corrosion inside the boiler 1) Boiler operating temperature too low (lower
than the dew point)
2) High percentage of sulphur in fuel oil
3) Fume temperature too low (below 180 °C)
1) Increase operating temperature
2) Change type of fuel oil
3) Replace the nozzle, increasing its capacity
Soot at the mouth of the chimney 1) Fumes cool down too much (below 180°C)
before reaching the mouth, due to an insuf-
ficiently insulated exterior chimney or to
infiltration of cold air
1) Increase chimney insulation and eliminate any
openings where cold air can enter
