What it is

The Worcester Bosch upper flue tube assembly, part number 87161069390, is the upper section of the flue run on a Worcester Bosch Greenstar gas boiler. It forms part of the flue path that takes combustion products away from the heat exchanger and out through the terminal. The tube is supplied as a single assembly and is matched to the flue system used across the Greenstar range.

Signs this part needs replacing

  • Visible corrosion, pitting or perforation on the flue tube surface
  • Staining or discolouration around the flue joint, suggesting leakage of combustion products
  • Condensate tracking or drips from the flue section
  • Boiler lockout or flue-related fault codes that persist after reset
  • Discolouration or heat damage to nearby components from a failing flue path

Before you order

  • Check the GC number and serial plate on the appliance to confirm the flue variant before ordering.
  • Confirm the alternative part number 1015109 against the existing component where the old part is still legible.
  • Inspect the flue seals and gaskets at the joint and replace them where they are perished or compressed.
  • This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
