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

TWO-STAGE GAS BURNERS: TROUBLE-SHOOTING GUIDE
POSSIBLE CAUSE
1) Disturbance to ionization current
from ignition transformer.
2) Flame sensor (ionization probe or
UV cell) inefficient.
3) Flame sensor (ionization probe or
UV cell) 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) UV cell dirty or greasy.
9) Equipment fault.
10) No ionization.
1) Fault in ignition circuit.
2) Ignition transformer
discharges to earth.
3) Ignition transformer
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
excessive.
4) Air flow between disk and head too
narrow.

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) Clean carefully.
9) Replace.
10) 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.
cable
3) Connect.
cable
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).
4) Adjust the disk/head opening.
