Frequently Asked Questions

Is the Viessmann 7834234 compatible with Vitodens 200 boilers?

Yes. This ionisation electrode is confirmed for the listed Vitodens 200 WB2B, WB2C, B2HB and B2KB combi and system boilers. Compatibility depends on the exact appliance model, output and serial number.

Does this electrode also fit Viessmann Vitodens 222-F boilers?

Yes. It is confirmed for the listed Vitodens 222-F B2TB, FS2A and FS2B models. Check the model output and serial number before ordering.

Are the gasket and screws included?

Yes. The Viessmann 7834234 ionisation electrode is supplied with a gasket and screws.

How can I confirm that 7834234 is the correct replacement?

Check the full boiler model, output, GC number and serial number against the compatibility list. You should also confirm that Viessmann manufacturer part number 7834234 matches the original component or official appliance parts information.

What symptoms may indicate an ionisation electrode problem?

Possible symptoms can include failed flame detection, repeated ignition attempts, intermittent burner shutdown or boiler lockouts. These symptoms do not automatically confirm that the electrode is faulty because ignition components, wiring, gas supply or boiler controls may cause similar problems.

Does this ionisation electrode require professional installation?

Yes. The electrode forms part of the boiler’s combustion and flame-safety system. Installation, combustion checks and operational testing should be completed by a suitably qualified Gas Safe registered engineer.
