HOW TO FIND THE CAUSES OF IMPROPER OPERATION AND TROUBLESHOOTING

PROBLEM
Appliance "locked out" due to no
flame (red light lit). Fault only in the flame
control device.
The equipment goes into "lock-out", gas
flows out, but there is no flame (red light
on). Fault in ignition circuit.
The equipment goes into "lock-out",
gas flows out, but there is no flame (red
light on).
POSSIBLE CAUSE
1) Disturbance in the ionisation current
caused by the ignition transformer.
2) Inefficient flame sensor (ionisation probe).
3) Flame sensor (ionisation probe) position
incorrect.
4) Ionisation probe or relative earth cable.
5) Flame sensor electrical connection cut-off.
6) Inefficient draught or fumes passage
blocked.
7) Flame disk or combustion heads dirty
or worn.
9) Faulty equipment.
10) Lack of ionisation.
1) Fault in ignition circuit.
2) Ignition transformer cable discharges to
earth.
3) Ignition transformer cable disconnected.
4) Ignition transformer faulty.
5) The distance between electrode and earth
is incorrect.
6) Isolator dirty and the 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 exces-
sive.
4) Air passage between disk and head too
narrow.

REMEDY
1) Invert the ignition transformer power supply
(230V side) and check using an analog
micro-ammeter.
2) Replace the flame sensor
3) Correct the position of the flame sensor, and
then check its efficiency by connecting the
analog micro-ammeter.
4) Check visually and using the tool.
5) Restore the connection.
6) Ensure that the boiler fumes passage and
chimney connection are free.
7) Visually check and replace, if necessary.
9) Replace.
10) If the "earth" of the equipment is not
efficient, the ionisation current cannot
be checked. Check the efficiency of the
"earth" at the terminal concerned in the
equipment and at the "earth" connection
of the electric system.
1) Check the ignition transformer power supply
(230V) and high voltage circuit (electrode
to earth or isolator broken under locking
terminal).
2) Replace.
3) Connect.
4) Replace.
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 the gas pipe again, taking great care.
3) Check the gas pressure value at the time
of ignition (use a water pressure gauge,
if possible).
4) Adjust the disk/head opening.
