Description
The Viessmann 200-W B2HA Ionization Electrode 7836489 is a brand-new genuine replacement component designed for selected Viessmann Vitodens 200-W B2HA boilers. Supplied under manufacturer part number 7836489, this ionization electrode comes with a 12-month warranty. Before ordering, always confirm your boiler model, output, serial number and manufacturer part number to ensure compatibility.
The ionization electrode monitors the burner flame by detecting the flame signal during operation. This safety component ensures the boiler only continues operating when a stable flame is present. A faulty ionization electrode may result in flame detection faults, ignition lockouts or intermittent boiler operation. As it forms part of the boiler’s combustion system, installation and testing should be completed by a suitably qualified Gas Safe registered engineer.
