10.4.1 Replacing the ionisation/ignition electrode
The ionisation/ignition electrode must be replaced if:
The ionisation current is < 4 µA.
The electrode is damaged or worn.
The electrode is included in the service kit.
1. Remove the plug of the electrode from the ignition transformer.
Important
The ignition cable is fixed to the electrode and therefore may not
be removed.
2. Unscrew the two screws on the electrode.
3. Remove the entire component.
4. Fit the new ionisation/ignition electrode.
5. Reassemble the unit in reverse order.
10.4.2 Checking the non-return valve
Check the condition of the non-return valve. Replace the non-return valve
if it is defective, there is one in the service kit, or if there are traces of
condensation on the inside of the fan. Do this as follows:
