Worcester Bosch Flue Duct Assembly 8716117694

The Worcester Bosch 8716117694 is a flue duct assembly used on Greenstar ErP Compact gas boilers. It forms part of the flue route, carrying products of combustion away from the heat exchanger and out through the terminal. The assembly is supplied as a direct replacement for the original duct fitted to these appliances.

• Visible corrosion, cracking or deformation of the duct during a service inspection
• Condensate staining or water marks around the flue joint or duct run
• Combustion readings outside the expected range, or a flue gas analyser indicating leakage
• Boiler lockout or flue-related fault codes on the appliance display
• Discolouration or heat damage at the duct connections

• Check the appliance GC number and model against the compatibility list to confirm the correct duct for your boiler
• The alternative part number 1030915 may be marked on the existing component or listed in older documentation
• Inspect the flue seals and gaskets at the same time, as these are commonly renewed when a duct is replaced
• This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
