What it is

The Ferroli 125mm outer wall flue seal is a boiler flue accessory used to seal the point where a 125mm flue passes through an external wall. It closes the gap between the flue pipe and the wall opening, keeping the penetration weathertight and preventing draughts and water ingress. It is listed by Ferroli under their accessories range for the boiler models below.

Signs this part needs replacing

  • Visible cracking, perishing or distortion of the existing wall seal
  • Draughts or cold air entering around the flue where it passes through the wall
  • Water staining, damp patches or dampness on the internal wall around the flue
  • The seal has come loose, dropped out of position or is missing altogether
  • Daylight or gaps visible around the flue at the external wall face

Before you order

  • Confirm the flue diameter is 125mm before ordering
  • Check your boiler model against the fitment list above
  • Inspect the existing seal and wall opening for damage that may need attention at the same time
  • Verify the part number 1KWMR09A against the manufacturer's parts list for your appliance
