What it is
The Worcester Bosch code plug 1122 (NG) is a configuration plug for the Worcester Bosch Greenstar 15I System boiler range. It is supplied in natural gas (NG) specification, which distinguishes it from the LPG version of the same appliance. The plug sets the appliance's gas type configuration.
Signs this part needs replacing
- Boiler fault codes or lockout linked to gas type or configuration settings.
- Combustion readings that do not match the expected natural gas values for the appliance.
- Boiler failing to run correctly after the code plug has been removed or refitted.
- Visible damage to the plug body or its connections.
Before you order
- Confirm the appliance is a Worcester Greenstar 15I System model.
- Check whether the boiler is natural gas or LPG — this is the NG version.
- Match the part number 87144311220 and code plug designation 1122 against the appliance's parts list.
- Inspect the existing code plug's markings before ordering.
