What it is

The Firebird Door Duroboard, part number ACC100GSK, is a combustion door insulation board for Firebird oil-fired boilers. It forms the insulating layer held within the combustion door assembly, where it shields the door from the heat of the combustion chamber. It is listed for Firebird Envirogreen models in the 80-100 kW range.

Signs this part needs replacing

  • Cracking, crumbling or breaking up of the board material
  • Charring, blackening or burnt patches across the insulation surface
  • Board no longer sitting flush or secure within the combustion door
  • Heat distortion or discolouration on the surrounding door metal
  • Dust or debris from a deteriorating board found in the combustion chamber

Before you order

  • Confirm the boiler model and output match the fit list for the 80-100 kW Envirogreen range
  • Check the combustion door board and door metal on removal, noting any damage to the door or its fixings
  • Isolate the boiler, allow it to cool and shut off the oil supply before removing the combustion door
  • Compare part number ACC100GSK against the old board or the appliance documentation
