Worcester Bosch Gas Conversion Kit GR8 35P NG 8737709374

This is a Worcester Bosch gas conversion kit, supplied under part number 8737709374 and listed as the GR8..35P NG kit. It contains the components needed to set a compatible boiler up to run on natural gas, and it belongs to the Greenstar 8000 Life and Greenstar 8000+ Style system boiler families. The kit is fitted at the appliance during commissioning or when an existing unit is being changed over to a different gas supply.

• The boiler is being commissioned on a gas supply that does not match the factory-set configuration.
• Combustion readings taken at the flue fall outside the range stated in the installation instructions.
• The flame picture is unstable, or the burner will not hold a steady light.
• Ignition or flame supervision faults appear shortly after a gas supply change.
• An existing conversion kit has been opened, damaged or partially used and cannot be relied on.

• Check the appliance GC number and model plate against the compatibility list before ordering, as the kit is specific to the 35 kW Greenstar 8000 and 8000+ Style system range.
• Confirm the gas type required for the installation; this kit is the NG variant.
• Have the alternative part number 8905072 to hand if you are cross-referencing against older documentation.
• This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
