TROUBLESHOOTING

PROBLEM
Appliance locked 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 limited to the ignition circuit.
The burner goes into "lock-out",
gas flows, but there is no flame
(red light on).
POSSIBLE CAUSE
• Disturbance to ionization current from
the ignition transformer.
• Flame sensor (ionization probe)
inefficient.
• Flame sensor (ionisation probe) position
incorrect.
• Ionization probe or relative earth cable.
• Electrical connection cut-off by flame
sensor.
• Inefficient draught or fumes passage
blocked.
• Flame disk or combustion heads dirty
or worn.
• Equipment fault.
• No ionization.
• Fault in ignition circuit
• Ignition transformer cable discharges
to earth.
• Ignition transformer cable disconnected.
• Ignition transformer faulty.
• The distance between electrode and
earth is incorrect.
• Isolator dirty, so electrode discharges to earth.
• Air/gas ratio incorrect.
• Gas pipe has not been properly bled of air
(in the case of first ignition).
• The gas pressure is insufficient or excessive.
• Air flow between disk and head too narrow.

SOLUTION
• Invert the ignition transformer power supply
(230V side) and check using an analogue
micro-ammeter.
• Replace flame sensor
• Correct the position of the flame sensor, and
then check its efficiency by connecting the
analogue micro-ammeter.
• Check visually and using the instrument.
• Restore the connection.
• Ensure that the boiler fumes passage and
chimney connection are free.
• Visually check and replace, if necessary.
• Replace.
• 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.
• Check the ignition transformer power supply
(230V) and high voltage circuit (electrode to
earth or isolator broken under locking terminal).
• Replace it.
• Connect.
• Replace it.
• Position at the correct distance
• Clean or change the isolator or electrode.
• Correct the air/gas ratio (there is probably too much
air or very little gas)
• Bleed the gas pipe again, taking great care.
• Check the maximum gas pressure value at the
time of ignition (use a water pressure gauge,
if possible).
• Adjust the disk/head opening.
