What it is

The Johnson & Starley flue gasket is a sealing component for the top heat exchanger connection on Johnson & Starley boilers. It seals the joint between the heat exchanger and the flue path, preventing combustion products from escaping into the appliance casing. It is listed by the manufacturer as a gasket for the heat exchanger (top).

Signs this part needs replacing

  • Visible cracking, hardening or flattening of the gasket material
  • Soot or dark staining around the top heat exchanger joint
  • Condensate or water tracking at the flue connection
  • Combustion odours or flue gases detected around the appliance casing
  • A carbon monoxide alarm activating near the boiler

Before you order

  • Confirm the boiler model against the fitment list above
  • Check the gasket position on the appliance, as this part is specified for the top heat exchanger connection
  • Inspect the mating surfaces for corrosion or distortion before refitting
  • Isolate the appliance and follow the manufacturer's instructions for flue and heat exchanger work
