What it is

The Worcester Bosch 8737709371 is a natural gas conversion kit for the Greenstar 8000 Life and 8000+ Style combi range. It is the kit specified by Worcester Bosch for setting these appliances to run on natural gas (NG). It is used when an appliance is converted between fuel types or when the gas train is being recommissioned to the correct fuel.

Signs this part needs replacing

  • The appliance is being changed between LPG and natural gas and the correct conversion kit is not fitted.
  • Combustion readings sit outside the range stated in the installation instructions after a fuel change.
  • The burner is difficult to light or the flame is unstable following work on the gas train.
  • Gas train components have been renewed and the appliance needs setting up to the correct fuel.
  • A conversion has been attempted using parts that do not match the appliance's GC number.

Before you order

  • Check the model and GC number on the appliance data badge against the compatibility list before ordering.
  • The alternative number 8905062 may appear on older paperwork in place of 8737709371.
  • Confirm the appliance's current fuel type and the fuel it is being converted to, as the kit is specified for natural gas (NG).
  • This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
