IRREGULARITY
Corrosion inside the boiler.
Soot at chimney outlet.
The burner goes into lock-out (red
light on). The fault is in the flame
control device.
The burner goes into lock-out
spraying liquid fuel but the flame
does not ignite (red light on).
The trouble is in the ignition device,
providing the fuel is not polluted with
water or other impurities and suffi
-
ciently atomised.
The equipment goes into “lock-out”,
gas flows out, but there is no flame
(red light on). Fault in ignition circuit.
POSSIBLE CAUSE
1 Boiler operating temperature too low
(below the dew point).
2 Smoke temperature too low, approxima
-
tely below 130 °C for diesel.
1 Excessive cooling of smoke (approxi
-
mately below 130°C) in the chimney, for
an outside chimney not adequately heat
insulated or cold air infiltration.
1 Flame sensor off or soiled with smoke
2 Insufficient draught.
3 Flame sensor circuit interrupted in the
equipment.
4 Dirty flame disk and diffuser.
1 Ignition circuit severed.
2 The ignition transformer cables are
discharging to ground.
3 The ignition transformer leads are not
properly connected.
4 Ignition transformer is faulty.
5 The electrode faces are not at the right
distance.
6 Electrodes discharge to earth becau
-
se they are dirty or their insulation
is cracked: check also the porcelain
insulator terminals.
REMEDY
1 Increase the operating temperature.
2 Increase diesel flow rate is the boiler
allows it.
1 Improve insulation and close any opening
letting cold air into the chimney.
1 Clean or replace.
2 Check all the smoke ducts in the boiler and
in the chimney.
3 Replace the equipment.
4 Clean.
1 Check the entire circuit.
2 Replace.
3 Restore the connection.
4 Replace.
5 Return to the required position.
6 Clean and if necessary replace them.
