What it is

The Ideal rear insulation panel, part number 172126, is a replacement thermal insulation component for Ideal Commercial Concord gas boilers. It is fitted at the rear of the appliance casing, where it limits heat transfer from the combustion area into the surrounding panels and casing. The panel also helps protect adjacent components from prolonged heat exposure and supports stable, efficient operation of the boiler.

This item was previously listed under the number 9422-9283.
