What it is

This is the side insulation panel for the combustion chamber, manufactured by Sime under part number 6139711. It forms part of the combustion chamber lining on Sime gas boilers, sitting against the chamber side wall to retain heat within the combustion zone. The insulation protects the surrounding casing and structural components from the heat generated during combustion.

Signs this part needs replacing

  • Visible cracking, crumbling or breakdown of the insulation material
  • Discolouration, scorching or charring beyond normal heat exposure
  • Insulation panel loose, detached or slumped from its seated position
  • Brittle or friable surface that sheds material when touched
  • Localised overheating or heat damage to nearby casing components

Before you order

  • Confirm the boiler model and GC number against the fitment list above
  • Check the appliance data badge to verify the exact Sime model variant
  • Inspect the opposite side and any other insulation panels in the chamber for similar deterioration
  • Confirm the part number 6139711 matches the insulation position required
