Description
Five failed burner starts:
No ignition spark:
Check the wiring between the PCU electronic PCB and
the ignition transformer.
Check that the SU electronic PCB is correctly in place.
Check the ionisation/ignition electrode.
Check breakdown to earth.
Check the condition of the burner set.
Check the earthing.
SU electronic PCB faulty: replace the electronic PCB.
Ignition spark but no flame:
Vent the gas pipes to remove air.
Check that the air inlet and flue gas discharge flues are
not blocked.
Check whether the gas tap is properly open.
Check the gas supply pressure.
Check the operation and setting of the gas valve unit.
Check the wiring on the gas valve unit.
SU electronic PCB faulty: replace the electronic PCB.
Presence of the flame but insufficient ionization (<4 µA):
Check whether the gas tap is properly open.
Check the gas supply pressure.
Check the ionisation/ignition electrode.
Check the earthing.
Check the wiring on the ionization/ignition electrode.
Gas leakage control fault:
Bad connection: check the wiring and connectors.
VPS gas leakage control defective: replace the GPS.
Gas valve unit faulty: replace the gas valve unit.
False flame signal:
The burner remains very hot: Set the O
Ionisation current measured but no flame should be pre
sent: check the ionisation/ignition electrode.
Faulty gas valve: replace the gas valve.
Faulty ignition transformer: replace the ignition transformer.
Fan fault:
Bad connection: check the wiring and connectors.
Fan operates when it should not be operating: check for ex
cessive chimney draught.
Faulty fan: replace the fan.
