What it is

A genuine Worcester Bosch code plug that sets a 9i System ErP boiler's control PCB to run on natural gas. Worcester Bosch's own listing titles it "Code_Plug NG 1426".

Signs this part needs replacing

  • The boiler is being converted to run on natural gas and needs the matching code plug fitted
  • The existing code plug is missing, damaged or set for the wrong gas type
  • A control PCB has been replaced and needs the correct gas-type code plug re-fitting
  • A Gas Safe engineer has identified a gas-type configuration mismatch on the appliance

Before you order

  • Confirm the appliance code on the boiler's data badge matches 7733600011 or 7733600033
  • Fitting must be carried out by a Gas Safe registered engineer, alongside the mechanical conversion kit where the gas type is being changed
  • Isolate the electrical supply before opening the control panel
