ANOMALY
Corrosion inside the boiler.
Soot at the mouth of the chimney.
The burner goes into lock-out (red
light on). The fault is in the flame
control device.
The burner goes to shut down
spraying liquid fuel but without fla
-
me presence (red light on).
The trouble is in the ignition devi-
ce, providing the fuel is not polluted
with water or other impurities and
sufficiently 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,
approximately below 130 °C for
diesel.
1
Excessive cooling of smoke
(approximately below 130°C) in the
chimney, for an outside chimney not
adequately heat insulated or cold
air infiltration.
1
Photoresistance severed or fouled
with smoke.
2
Insufficient draught.
3
Flame detector circuit interrupted in
the equipment.
4
Dirty deflector disk and diffuser.
1
Ignition circuit severed.
2
The ignition transformer cables are
discharging to ground.
3
The ignition transformer cables are
not well connected.
4
Ignition transformer is faulty.
5
The electrode faces are not at the
right distance.
6
Electrodes discharge to earth
because 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 ope-
ning 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.
