INSTRUCTIONS FOR DETERMINING THE CAUSE LEADING TO IRREGU-
LARITIES IN THE OPERATION AND THEIR ELIMINATION
irregularitY
The burner does not start.(The
equipment does not perform the
start up program).
Defective flame with sparks.
Flame not properly shaped with
presence of smoke and soot.
Defective flame, flickering or pro
-
truding from combustion orifice.
poSSible cauSe
1 Thermostats (boiler or room) or pressure
switches are open.
2 Flame sensor 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 flame disk.
5 Too much combustion air.
6 Air passage between flame disk and diffu
-
ser excessively closed.
remedY
1 Raise the thermostats settings, or wait that
the contacts close for natural decrease of tem-
perature 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.
