What it is

The SEAL - FAN OUTLET is a Potterton sealing component that fits at the fan outlet on the flue side of the fan assembly. It seals the joint between the fan outlet and the flue path, preventing combustion products from escaping into the appliance casing. The part is supplied by Potterton under part number 10/18843.

Signs this part needs replacing

  • Visible cracking, hardening or flattening of the seal at the fan outlet
  • Soot staining or condensate tracking around the fan outlet joint
  • A seal that no longer sits correctly in its seating when the fan is refitted
  • Combustion readings that fall outside expected limits on a service check

Before you order

  • Confirm the boiler model and GC number against the fits list above
  • Check the existing seal at the fan outlet and note its condition and seating position
  • Verify the part number 10/18843 matches the number shown on the appliance or in its documentation
