What it is

The Ideal fan recuperator seal is a replacement sealing component for the combustion chamber area of Ideal Classic HE and Optia boilers. It sits at the recuperator, the section where heat is recovered from the flue path, and its job is to stop water and harmful gases escaping as they pass through the appliance. The seal is supplied as an Ideal Spares part under reference 174146.

Signs this part needs replacing

  • Visible cracking, hardening or flattening of the seal when the combustion chamber is opened
  • Soot staining or discolouration around the recuperator and adjacent casing
  • Combustion readings that drift or fail to settle after servicing
  • Traces of water or condensate weeping past the recuperator joint
  • The seal breaking up or sticking to mating faces during strip-down

Before you order

  • Confirm the boiler model and GC number against the compatibility list, as the same seal reference covers several Classic HE variants
  • Check the existing seal against part number 174146 and the alternative reference 1179866 before ordering
  • Inspect surrounding gaskets and seals while the combustion chamber is open, as they may need replacing at the same time
