What it is

This is a flue gas outlet sealing ring with a 250 mm flue diameter, manufactured by Broag for its commercial boiler ranges. It seals the flue gas outlet connection, preventing flue gases and condensate from escaping at the joint. The part is supplied in a pack of two.

Signs this part needs replacing

  • Visible cracking, flattening or hardening of the sealing ring
  • Flue gas odour around the flue outlet joint during operation
  • Condensate weeping or staining at the flue connection
  • Seal distorted or displaced from its seating on inspection
  • Damage found during routine flue or combustion analysis checks

Before you order

  • Confirm the flue outlet diameter is 250 mm
  • Check the boiler model and output rating against the fit list
  • Confirm how many seals are required for the flue joint being worked on
  • Inspect the flue outlet and mating faces for damage before refitting
