What it is

The Ariston 64202303 is an ionisation electrode conversion kit designated for THL 65-145 appliances. The ionisation electrode sits in the burner and provides the flame-proving signal to the boiler's control board, allowing the appliance to confirm ignition and continue running. This kit is supplied as the conversion assembly for the THL designations stated in the part name.

Before you order

  • Check the appliance data badge and confirm the model and part number against the manufacturer's parts list for that appliance.
  • Verify the appliance falls within the THL 65-145 designation covered by this kit.
  • Compare the existing ionisation electrode and its lead with the kit before ordering.
  • The electrode forms part of the combustion circuit, so fitting should be carried out by a Gas Safe registered engineer.
