Reason
Flame signal lost during operation.
Cause:
Incorrect gas supply pressure.
Corrective Action:
Be aware that the nominal gas inlet pressure must be met under all operation conditions.
Check the incoming gas supply pressure is correct. Contact the gas transported if incorrect.
Check if all gas valves in the supply line are completely open.
Check if the gas supply pipework is correctly sized.
Check if the dirt filter mesh in the gas valve inlet is clean.
Check that any external dirt filter in the gas supply line is not blocked.
Check if an external gas pressure regulator is selected/installed correctly.
Cause:
Incorrect gas valve settings.
Corrective Action:
Check and set gas valve settings.
Cause:
Faulty gas valve.
Corrective Action:
Replace gas valve.
Cause:
Faulty electrode/electrode wiring affecting the ionisation signal.
Corrective Action:
Check ionisation signal.
Check the condition of the ignition electrode and clean/replace if necessary.
Check the distance between the electrode pin, earth pin and burner.
Check the condition of the ignition cable and replace if necessary.
Check the condition of the earth wire/connection of the ignition electrode and replace if necessary.
Check for correct electrical earthing of the boiler.
Cause:
Flue gas and/or air supply system fault.
Corrective Action:
Check all seals in the flue gas and air supply system.

Reason
Flame signal detected, when no heat demand is present.
Cause:
The flame detection circuit detects a flame which is not supposed to be present.
Corrective Action:
Check the condition of the ignition electrode and clean/replace if necessary.
Check the incoming power supply for correct polarity.
Check the incoming power supply for incorrect frequency or voltage peaks.
Check external wiring for voltage feedback.
Check the internal wiring for bad connections.
Check if the gas valve is closing correctly.
Replace the burner control PCB.
Check the condition of the ceramic insulator. Replace electrode if any sign of damage is present.
Check if the design of the flue gas and air supply system complies with the maximum combined resistance as specified.
Check if the flue gas and air supply system is installed in accordance with the relevant standards.
