Worcester Bosch Code Plug 12i System LPG 8716117169

The Worcester Bosch 8716117169 is a code plug for the Greenstar 12i ErP System boiler range. It carries the configuration data the control board reads at start-up, including the gas type the appliance is set to run on, so the boiler's operating parameters match the fuel supply it is connected to. This version is the LPG specification for the 12i System model.

Code plugs are small, low-cost components, but the boiler will not run correctly if the wrong one is fitted or if the plug is damaged. They are commonly replaced during gas conversion work, after control board replacement, or when a plug has been disturbed and its contacts no longer make a reliable connection.

• The boiler fails to fire or locks out after a change of gas type or a conversion.
• Fault codes appear that relate to appliance configuration or fuel setting.
• Combustion readings sit outside the range expected for the appliance and fuel.
• The plug has been removed during board or control work and its contacts are damaged or corroded.
• The boiler runs, but the commissioned settings no longer match the fuel supply in use.

• Confirm your appliance model and GC number against the compatibility list before ordering.
• Check whether the boiler is set up for LPG or natural gas; this plug is the LPG variant.
• Cross-reference the alternative number 1031331 if you are working from an older parts list.
• This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
