What it is

This is the combustion chamber insulation supplied by Ideal for its Commercial Concord range. It is the moulded insulating component that lines the combustion chamber, holding heat inside the chamber so the burner area reaches and maintains correct operating temperature while the outer casing stays cooler. The part is listed under Ideal part type INSULATIONS and is supplied complete under the CPLT reference.

Signs this part needs replacing

  • Insulation board cracked, crumbling or breaking away from the chamber lining
  • Surface discoloured, charred or showing signs of localised overheating
  • Insulation material flaking or shedding dust when the chamber is opened
  • Heat damage or scorching visible on adjacent panels and casing
  • Insulation no longer sitting flush against the chamber, leaving gaps around the burner area

Before you order

  • Confirm the appliance model and serial number against the compatibility list before ordering, as the Concord ES140/H and ESi 140 CPT variants use different configurations.
  • Check the number on the existing insulation: this part is listed against previous number 8358-8791 and alternative number 1178489.
  • Assess whether any gasket, seal or fastener disturbed during removal also needs replacing, as these are not supplied with the insulation.
  • This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
