What it is

The Worcester Bosch 8716177744 is a conversion kit that changes a Greenstar ErP Compact boiler from natural gas (NG) to liquefied petroleum gas (LPG). It is produced by Worcester Bosch for the 25Si and 28Si ErP Compact range and supplies the fuel-specific components needed to set the appliance up for LPG operation. Fitting the correct kit allows the burner and gas valve to be configured for the gas being supplied to the property.

Signs this part needs replacing

  • The boiler is being switched from natural gas to LPG and needs the matching fuel-specific components.
  • Combustion readings fall outside the LPG specification for the appliance after a change of gas supply.
  • Flame lift, an unstable flame or sooting at the burner.
  • Repeated ignition failure or lockout following a change of gas supply.

Before you order

  • Check the GC number and model on the appliance data badge against the compatibility list.
  • Confirm the boiler is a Greenstar 25Si or 28Si ErP Compact before ordering.
  • This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
