What it is

The Worcester Bosch 8737709368 is a natural gas (NG) conversion kit for the Greenstar 8000 Life and 8000+ Style combi platform. It carries the gas-side components that sit in the gas train of the GR8.30C appliance, regulating and delivering gas to the burner so the boiler runs correctly on natural gas. The kit is listed by Worcester under spare part type Gas Valves and is the NG variant for this appliance group.

Signs this part needs replacing

  • The boiler will not run correctly on the gas supply it has been set up for, with combustion readings outside the expected range.
  • Unstable or poorly formed flame at the burner, or flame that fails to hold during ignition.
  • Repeated ignition faults or lockouts shortly after a gas type change or service.
  • Gas train components showing contamination, damage or wear on inspection.
  • A conversion or commissioning check that cannot be completed because the gas-side parts are incorrect for the appliance.

Before you order

  • Check the appliance GC number and serial plate against the compatibility list to confirm the kit suits your model.
  • Confirm the alternative part number 8905050 if you are matching against older documentation or stock records.
  • Check whether any gasket or seal in the gas train also needs renewing at the same time.
  • This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
