ACV Insulated keranap 51401013

ACV Insulated keranap 51401013 is a ceramic fibre insulation panel with dimensions of 342 x 195 x 12 mm. It is designed for use in ACV boilers, including models DELTA G HRn, Smart 210, Smart 240, and Compact Condens 27. This panel is installed inside the boiler housing to line the combustion chamber or seal joints, containing heat and protecting surrounding components from excessive temperatures.

Parts of this type are selected by appliance model and specific position in the assembly, not by general material specifications. Before ordering, compare the dimensions and cut-out pattern against the old pad to ensure an exact match. When fitting, check that the replacement sits flush against chamber walls with no gaps at the edges. If the insulation is part of a door or access panel seal, ensure the gasket surface is clean and the closing mechanism compresses the pad evenly.

Combustion chamber insulation degrades over time due to repeated thermal cycling. Cracks, crumbling, or compression can reduce insulating properties, leading to hot spots that may damage the boiler casing or adjacent parts. Inspect the pad for these signs and replace it if any are present.
