What it is

The Ideal 176250 is a flue outlet seal carrying the D150 size designation, supplied by Ideal for use on its commercial appliance range. It sits at the flue outlet, sealing the joint between the flue components and the appliance casing so that products of combustion leave through the flue rather than escaping into the plant room. The seal also helps hold the flue connection steady against vibration and thermal movement.

Signs this part needs replacing

  • Visible cracking, hardening or flattening of the seal at the flue outlet
  • Soot staining or discolouration around the flue connection and appliance casing
  • Condensate weeping or damp tracking at the flue outlet joint
  • Draughts or a smell of combustion products near the flue connection
  • Flue gas readings that drift or fail to settle during a service or combustion check

Before you order

  • Confirm the appliance model and, where available, the serial number against the compatibility list before ordering
  • Check the existing seal against the D150 size designation and the part number 176250
  • Note the alternative number 1180337 when cross-referencing older documentation
  • This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
