What it is

The Ideal Classic HE casing seal and screws kit, part number 174070, is a service component for the Ideal Classic HE family of domestic gas boilers. The seal closes the joint between the boiler casing panels, holding back heat and flue gases, while the screws secure those panels in position. It sits within the gaskets, o-rings, seals and washers group of spares.

Signs this part needs replacing

  • The casing seal is visibly perished, cracked, flattened or torn
  • Staining, discolouration or heat marking around the casing joints
  • Casing screws corroded, seized, rounded or missing after earlier servicing
  • The seal has shifted or been damaged while panels were removed for maintenance
  • Draughts or heat escaping at the edge of the casing

Before you order

  • Check the appliance GC number on the boiler data badge against the compatibility list before ordering.
  • The alternative part number 1179801 may appear on older paperwork for the same kit.
