INSTRUCTIONS FOR DETERMINING THE CAUSE LEADING TO IRREGULARITIES IN THE
OPERATION AND THEIR ELIMINATION
IRREGULARITY
Appliance locks 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 ionization current
from the ignition transformer.
2 Flame sensor (ionization probe)
inefficient.
3 Flame sensor (ionisation probe)
position incorrect.
4 Ionization probe or relative ground
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 cable disconnected.
4 Ignition transformer is faulty.
5 The distance between electrode
and ground is incorrect.
6 Insulator dirty, so electrode
discharges to ground.
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.
REMEDY
1 Invert the ignition transformer power
supply (230V side) and check using an
analogue micro-ammeter.
2 Replace the flame sensor.
3 Correct the position of the flame
sensor, and then check 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 “earth” of the equipment is not
efficient, do not check the ionization
current.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 it.
3 Connect it.
4 Replace it.
5 Position it at the correct distance.
6 Clean or change the insulator or
electrode.
1 Correct the air/gas ratio (there is
probably too much air or very little gas)
2 Bleed the gas pipe again, with due
caution.
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.
