HOW TO FIND THE CAUSES OF IMPROPER OPERATION OF TWO-
STAGE GAS BURNERS AND TROUBLESHOOTING
PROBLEM
The equipment goes into "lock-out" with
the flame (red light on). 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 to ionisation current caused
by the ignition transformer.
2) Inefficient flame sensor (ionisation
probe).
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.
8) Faulty equipment.
9) 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 dir t y and so 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 passage between the disk and
the head is 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.
8) Replace.
9) 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.
