What it is

The Worcester Bosch 87107352990 is a flue gas duct, supplied as part of the flue assembly for Worcester Bosch gas boilers. It forms part of the sealed route that carries products of combustion from the heat exchanger out to the flue terminal. The duct is listed against the Worcester British Gas Greenstar range and the associated 430/I and 532/I families.

Signs this part needs replacing

  • Visible corrosion, staining or white condensate marking on the duct or at its joints
  • Condensate weeping from a flue joint or from the duct where it passes through the casing
  • Boiler locking out or reporting a flue-related fault code during or after ignition
  • Discolouration, heat damage or distortion of the duct or its seals
  • Evidence of combustion products escaping at a joint rather than at the terminal

Before you order

  • Check the appliance GC number and serial plate against the compatibility list before ordering, as the same boiler family can use different flue assemblies.
  • Confirm the part number on the existing duct or in the installation manual matches 87107352990 or the alternative number 1012559.
  • Check whether the flue joint seals or gaskets on the appliance also need renewing at the same time.
  • This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
