What it is

The Ideal 174162 is a heat engine gasket kit supplied by Ideal for its ICOS HE and Mexico HE boiler ranges. It provides the sealing elements used when the heat engine assembly is stripped and rebuilt, closing the joints between the heat exchanger and its mating components. A sound seal at these points keeps water inside the circuit and combustion products inside the flue path.

Signs this part needs replacing

  • Weeping or staining at the heat engine joints after the boiler has been running
  • Gasket material that has hardened, flattened or cracked with heat cycling
  • A gasket that breaks up or delaminates when the heat engine is stripped down
  • Combustion readings that drift, or flue gas odours around the casing
  • Any heat engine rebuild, where the original seals cannot be reused

Before you order

  • Confirm the appliance model and GC number against the compatibility list before ordering
  • Compare the existing gasket with the kit contents during strip-down
  • Cross-reference the alternative number 1781310 if the original number is not listed on the appliance
