What it is

The IO-electrode Ni-Ferral 13–19 kW is a Viessmann electrode assembly used in the ignition and flame-monitoring circuit of compatible gas boilers. The electrode sits in the combustion path, where it provides the ignition spark and/or flame ionisation signal that the control board uses to prove a flame. It is supplied under Viessmann part number 7834232 and is intended for the 13–19 kW output range.

Signs this part needs replacing

  • The boiler repeatedly locks out during the ignition sequence
  • Ignition is intermittent, with the burner failing to light on the first attempt
  • The flame is established but the control board does not detect it and shuts the burner down
  • Visible erosion, cracking, soiling or distortion at the electrode tip or insulator

Before you order

  • Confirm the appliance is a Viessmann Vitodens 343-F Ws4A and that the serial number matches the fitment listed
  • Check the appliance output falls within the 13–19 kW range stated for this electrode
  • Inspect the existing electrode, its lead and its connection point before ordering a replacement
  • Compare the part number on the existing component against Viessmann 7834232
