What it is

The Worcester Bosch code plug 1132 is a configuration component for Greenstar 25SI Combi appliances, used to set the low NOx option on natural gas models. It is fitted to boilers from FD 988 onwards. The plug tells the control board which combustion configuration the appliance should run.

Signs this part needs replacing

  • Combustion analysis readings fall outside the expected range for a low NOx appliance
  • The boiler is not running to its low NOx configuration after a board change
  • Fault codes indicating a code plug or configuration mismatch
  • Unstable or incorrect combustion performance following service work

Before you order

  • Confirm the appliance is a Greenstar 25SI Combi
  • Check the boiler's FD number is 988 or later
  • Verify the gas type is NG
  • Compare the existing code plug number against 1132 before ordering
