TROUBLESHOOTING INSTRUCTIONS
ANOMALY
The burner does not start up.(The
equipment does not perform the
start up program).
Poor flame, with sparks.
Poorly shaped flame with smoke
and soot.
Defective flame, flickering or
protruding from combustion head.
POSSIBLE CAUSE
1 Thermostats (boiler or room) or
pressure switches are open.
2 Photoresistant-cell in short circuit.
3 Absence of line voltage, main switch
open, meter switch tripped or absence
of line voltage.
4 Thermostat line not wired according to
diagram or open thermostats.
5 Equipment internal fault.
1 Spraying pressure is too low.
2 Too much combustion air.
3 Nozzle inefficient because dirty or
worn.
4 Water in the fuel.
1 Insufficient combustion air flow.
2 Nozzle inefficient because dirty or
worn.
3 Nozzle capacity too low with respect to
combustion chamber volume.
4 Combustion chamber unsuitably
designed or too small.
5 Unsuitable refractory coating (it
reduces excessively the space of the
flame).
6 Boiler or chimney ducts blocked.
7 Spraying pressure is low.
1 Excessive draught, only when there is
an extractor in the chimney.
2 Nozzle inefficient because dirty or
worn.
3 Water in the fuel.
4 Dirty deflector disk.
5 Too much combustion air.
6 Air passage between deflector disk
and diffuser excessively closed.
REMEDY
1 Raise the thermostats settings, or
wait that the contacts close for natural
decrease of temperature or pressure.
2 Replace it.
3 Activate switches or wait for power to
return.
4 Check the connections and thermostats.
5 Replace it.
1 Restore it at the required value.
2 Reduce combustion air
3 Clean or replace.
4 Drain water from the tank using a suitable
pump. Never use the burner pump for this
purpose.
1 Increase combustion air.
2 Clean or replace.
3 Decrease diesel flow rate to suit the
chamber (thermal power will obviously
be lower than necessary) or replace the
boiler.
4 Increase nozzle flow by replacing it.
5 Modify it, carefully abiding by the
instructions given by boiler manufacturer.
6 Arrange for cleaning.
7 Restore it at the required value.
1 Adjust the suction fan speed by changing
the pulley diameter.
2 Clean or replace.
3 Drain water from the tank using a suitable
pump. Never use the burner pump for this
purpose.
4 Clean.
5 Reduce combustion air.
6 Correct the position of the combustion
head regulating device.
