9.4 Instructions

After identifying the problem, use the Case number to find
the possible cause in this paragraph.
Case 1: Flame lasts only 5 seconds after ignition.
• The flame is not detected:
– Check the ignition/ionisation cable and the
electrode. The cable should have a resistance
of 1 kΩ.
• The air heater is not earthed properly.
• The circuit board is defective.
Case 2: No flame after ignition.
• There is not enough gas pressure.
• The gas mixture is too poor:
– Adjust the gas valve (see §8.1).
• The gas valve does not open:
– During ignition, check for a 230 V voltage on
the valve.
• Check if the ignition electrode sparks. If not:
– Check the cable and electrode and replace
them when damaged.
– Check the burner control unit and replace it
when it does not give a spark output.
Case 3: Heat exchange sensor or flue sensor is overheated.
• Check if the connectors J12 and J6 are plugged in
correctly and if the connection J12[1-4] (optional
overheating protection) is closed.
• Check if the system fan supplies enough air.
• Check the settings of the gas valve. The heater may
be overfired. If so:
– Adjust the burner pressure.
Case 4: Heat exchange sensor or flue sensor not detected,
or short circuit.
NOTICE L-25 refers to the heat exchange sensor. L-26
refers to the flue sensor, if applicable.
