What it is
The Worcester Bosch 87144317030 is a code plug, marked 1703 LPG, used across the Greenstar Highflow 550CDi family of combination boilers. The plug carries the configuration data the control board reads to establish the appliance's fuel and gas family settings. Fitting the correct code plug ensures the PCB applies the right operating parameters for the boiler it is installed in.
