TROUBLESHOOTING INSTRUCTIONS
ANOMALY
Appliance locked out due to no
flame (red light lit).The fault is in
the flame control device.
The burner goes into “lock-out”,
gas flows, but there is no flame (red
light on).Fault in ignition circuit.
The burner goes into “lock-out”,
gas flows, but there is no flame
(red light on).
POSSIBLE CAUSE
1
Disturbance to ionisation current
from the ignition transformer.
2
Flame sensor (ionisation probe)
inefficient.
3
Flame sensor (ionisation probe)
position incorrect.
4
Ionisation probe or relative ground
cable.
5
Electrical connection cut-off by
flame sensor.
6
Inefficient draught or fumes
passage blocked.
7
Flame disc or combustion heads
dirty or worn.
8
Faulty equipment.
9
No ionisation.
1
Fault in ignition circuit
2
Ignition transformer cable
discharges to earth.
3
Ignition cable disconnected.
4
Ignition transformer faulty.
5
The distance between electrode
and ground is incorrect.
6
Isolator dirty, and electrode
discharges to earth.
1
Air/gas ratio incorrect.
2
Gas pipe has not been properly
bled of air (in the case of first
ignition).
3
The gas pressure is insufficient or
excessive.
4
Air flow between disc and head too
narrow.
REMEDY
1
Invert the ignition transformer power
supply (230V side) and check using an
analogue micro-ammeter.
2
Replace flame sensor.
3
Correct the position of the flame
sensor, and then check for its efficiency
by connecting the analogue micro-
ammeter.
4
Check visually and using the instrument.
5
Restore the connection.
6
Ensure that the boiler fumes passage
and chimney connection are free.
7
Visually check and replace, if necessary.
8
Replace it.
9
If the “ground” of the equipment is
not efficient, there is no ionisation
current.Check the efficiency of the
“earth” at the terminal concerned in the
equipment and at the “earth” connection
of the electrical system.
1
Check the ignition transformer power
supply (230V) and high voltage circuit
(electrode to earth or isolator broken
under locking terminal).
2
Replace it.
3 Connect.
4
Replace it.
5
Position at the correct distance.
6
Clean or change the isolator or
electrode.
1
Correct the air/gas ratio (there is
probably too much air or very little gas).
2
Bleed out the gas pipe again, taking
great care.
3
Check the maximum gas pressure
value at the time of ignition (use a water
pressure gauge, if possible).
4
Adjust the disc/head opening.
