Worcester Bosch Flue Gas Collector Greenstar FS 8716119320

The flue gas collector is the component that gathers combustion gases leaving the heat exchanger and directs them into the flue path on Worcester Bosch Greenstar FS and HE Plus appliances. It sits within the flue assembly group and plays a direct part in keeping combustion and flue performance stable across the operating range. This example is supplied under Worcester Bosch part number 8716119320.

• Combustion readings that drift outside the expected range and cannot be corrected by adjustment alone
• Visible corrosion, cracking or distortion on the collector body or its sealing faces
• Condensate or staining around the collector, suggesting a poor seal or a blocked path
• Flue-related fault codes or lockouts that return after the flue has been checked and cleared
• Soot deposits or debris collecting in the gas path, indicating the collector is no longer routing gases cleanly

• Check the appliance GC number and model plate against the compatibility list before ordering, as several Greenstar FS and HE Plus variants use different flue components
• Confirm the part number on the existing component matches 8716119320 or the alternative number 1031595
• Inspect the mating gasket or seal and replace it if it is compressed, hardened or damaged
• This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
