INSTRUCTIONS FOR DETERMINING THE CAUSE LEADING TO
IRREGULARITIES IN THE BURNER OPERATION AND THEIR ELIMINATION
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 (ionization probe) position
incorrect.
• Ionization probe or relative ground 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 ground.
• Ignition transformer cable disconnected.
• Ignition transformer is faulty
• The distance between electrode and
ground is incorrect.
• I s o l a t o r d i r t y, s o e l e c t r o d e
discharges to ground.
• 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 it.
• If the "ground" of the equipment is not
efficient, do not check the ionization current.
Check the efficiency of the "ground" at the
terminal concerned in the equipment and
at the "ground" connection of the electric
system.
• Check the ignition transformer power
supply (230V) and high voltage circuit
(electrode to ground or isolator broken
under locking terminal).
• Replace it.
• Connect it.
• 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.
