TWO-STAGE GAS BURNERS: TROUBLE-SHOOTING GUIDE
DETAILS OF PROBLEM
The apparatus goes into "lock-out" with the
flame (red light on). Fault restricted to flame
control device
The apparatus goes into "lock-out", gas flows
out, but there is no flame (red light on).Fault
restricted to ignition circuit.
The apparatus goes into "lock-out", gas flows
out, but there is no flame (red light on).
POSSIBLE CAUSE
1) Disturbance to ionization current from
ignition transformer.
2) Flame sensor (ionization probe) ineffi-
cient.
3) Flame sensor (ionization probe) position
incorrect.
4) Ionization probe or relative earth cable.
5) Electrical connection cut-off by flame
sensor.
6) Inefficient draught or fumes passage
blocked.
7) Flame disk or combustion heads dirty
or worn.
8) Equipment fault.
9) No ionization.
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, 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 ex-
cessive.
4) Air flow between disk and head too narrow. 4) Adjust the disk/head opening.

SOLUTION
1) Invert the ignition transformer power
supply (230V side) and check using an
analog micro-ammeter.
2) Replace flame sensor.
3) Correct the position of the flame sensor,
and then check its efficiency by inserting
the analog 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.
9) If the "earth" of the apparatus is not
efficient, do not check the ionization
current. Check the efficiency of the
"earth" at the terminal concerned of the
apparatus 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 replace isolator and 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 maximum gas pressure value
at the time of ignition (use a water
pressure gauge, if possible).
