What it is

This is a burner insulation component manufactured by Vaillant, listed under part number 295404. It is fitted to the right or left side of the burner assembly on Atmocraft VK gas boilers, where it provides thermal insulation around the burner area. The part sits within the combustion path and is subject to heat over the life of the appliance.

Signs this part needs replacing

  • Visible cracking, crumbling or breakdown of the insulation material
  • Discolouration or scorching indicating prolonged heat exposure
  • Insulation detaching from its seating or falling away in sections
  • Soot deposits or debris collecting around the burner area
  • Combustion readings drifting outside the expected range on service

Before you order

  • Confirm your appliance model against the fit list above
  • Check the existing insulation to establish whether the right or left position is required
  • Verify the part number 295404 against the manufacturer's parts list for your boiler
  • Inspect the burner assembly for any other heat-damaged components while access is available
