Sime Front Insulation 6326943

The Sime 6326943 is a front insulation panel manufactured by Sime for the Murelle ONE HE 25 boiler. It sits at the front of the appliance's combustion or heat exchanger area, reducing heat loss to the casing and helping maintain stable operating temperatures. Insulation panels of this type also protect surrounding components from radiated heat.

• The insulation panel is crumbling, flaking or breaking up when touched
• Visible blackening, scorching or heat damage across the panel surface
• Moisture staining or damp patches on the insulation, indicating a leak nearby
• The panel has been torn or dislodged during servicing or component access
• Exposed casing or adjacent parts running noticeably hotter than usual

• Confirm the appliance is a Sime Murelle ONE HE 25 and check the model data badge
• Check the existing panel's position and condition to confirm it is the front insulation that is required
• Verify the part number 6326943 against the manufacturer's parts list for your appliance
• Isolate the appliance and allow it to cool before removing or fitting insulation
