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.
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 Unsuitable refractory coating (it
reduces excessively the space of the
flame).
5 Boiler or chimney ducts blocked.
6 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 thermosta-
ts.
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 sui-
table pump. Never use the burner pump
for this purpose.
1 Increase combustion air.
2 Clean or replace.
3 Increase nozzle flow by replacing it.
4 Modify it, carefully abiding by the in-
structions given by boiler manufacturer.
5 Arrange for cleaning.
6 Restore it at the required value.
1 Adjust the suction fan speed by chan-
ging the pulley diameter.
2 Clean or replace.
3 Drain water from the tank using a sui-
table 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.
