What it is

The Worcester Bosch 87190010790 is a conversion kit that changes a compatible Greenstar combi boiler from liquefied petroleum gas (LPG) operation to natural gas. It contains the components needed to re-jet and re-configure the appliance for the alternative gas family. The kit belongs to the Worcester Bosch Greenstar range and is supplied for use on the 542/I and 42CDI Classic combi variants.

Signs this part needs replacing

  • The property gas supply has changed between LPG and natural gas and the boiler still runs on the original gas family setting.
  • The appliance has been moved or re-commissioned and the burner is not set up for the gas being supplied.
  • Combustion readings fall outside the expected range for the gas family in use.
  • The existing conversion components are damaged, missing or have been removed during earlier work.
  • A replacement boiler or heat exchanger has been fitted and the gas family configuration needs to be re-established.

Before you order

  • Check the appliance GC number and model plate against the compatibility list to confirm the correct kit for your boiler.
  • Confirm the gas family the appliance is currently set for and the gas family it needs to run on.
  • Note the alternative number 1022757 when cross-referencing older documentation.
  • This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
