Probable causes
No ignition
4
Ignition arc, but no flame
4
formation
Presence of the flame but
4
insufficient ionization (<3
µA)
Gas pressure non-existent
4
or too low
Wiring fault
4
Incorrect adjustment of the
4
VPS switch
Pressure switch VPS is not
4
or badly fitted
Defective VPS pressure
4
switch
Gas valve defective
4
Ionization current present
4
when there should not be a
flame
The burner remains very
4
hot: CO too high
2
Ignition transformer
4
defective
Gas valve defective
4
Bad connection
4
Defective SU PCB
4
Bad connection
4
Fan defective
4
Water circulation direction
4
reversed
Bad connection
4
Sensor not or badly
4
connected
Sensor fault
4
Checking / solution
Check cabling of ignition transformer
4
Check the ionization/ignition electrode
4
Check breakdown to earth
4
Check the earthing
4
Defective control SU PCB
4
Check that the air inlet and flue gas discharge flues
4
are not blocked
Check that the gas valve is fully opened
4
Check the supply pressure
4
Purge the gas supply to remove air
4
Check the operation and setting of the gas valve unit
4
Check the condition of the burner set
4
Check the wiring on the gas valve unit
4
Defective control SU PCB
4
Check that the gas valve is fully opened
4

4
Check the wiring on the ionization/ignition electrode
4
Check the earthing
4
Check the ionization/ignition electrode
4
Check the operation and setting of the gas valve unit
4
Check the condition of the burner set
4
Check that the gas valve is fully opened
4
Check the supply pressure
4
Check the wiring
4
Check whether the VPS gas pressure control
4
system has been correctly fitted
Check that the VPS switch has been adjusted
4
correctly
Replace the VPS gas pressure control system if
4
need be
Check the gas valve and replace if necessary
4
Check the ionization/ignition electrode
4
Set the CO
4
2
Replace the ignition transformer if necessary
4
Check the gas valve and replace if necessary
4
Check the wiring
4
Inspect the SU PCB and replace it if need be
4
Check the wiring
4
Check for adequate draw on the chimney
4
connection
Replace the fan if need be
4
Check the circulation (direction, pump, valves)
4
Check that the sensor has been correctly fitted
4
Check that the sensors are operating correctly
4
Replace the sensor if necessary
