What it is

The Ideal 172123 is a rear insulation panel for the combustion chamber, supplied by Ideal for its Commercial Concord range of boilers. It sits against the rear wall of the combustion chamber, shielding the surrounding casing and structure from radiant heat and helping to hold stable chamber temperatures during operation. Over time the board degrades and is replaced as part of chamber servicing or repair.

Signs this part needs replacing

  • Cracking, crumbling or flaking of the insulation board surface
  • Scorching or heavy discolouration on the rear chamber wall behind the panel
  • Insulation material breaking away and dropping into the combustion chamber
  • Combustion readings that drift or will not settle after servicing
  • Localised heat damage or distortion around the rear of the chamber

Before you order

  • Confirm the appliance model and serial number against the compatibility list before ordering.
  • Cross-reference the alternative and previous numbers 1178508 and 9422-9280 if the existing panel is marked differently.
  • This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
