What it is

The Biasi flange burner door, part BI1663103, is the burner mounting flange assembly used on Biasi Basica COND and Rinnova Adaptive condensing boilers. It carries the burner and seals against the heat exchanger face to keep the combustion chamber gas-tight.

Signs this part needs replacing

  • Visible heat damage, distortion or cracking around the flange face
  • Soot deposits or scorching on the burner door
  • Combustion readings drifting or an unstable flame
  • Signs of flue gas leakage at the burner mounting face
  • The sealing face no longer seats cleanly against the heat exchanger

Before you order

  • Confirm your boiler model and GC number against the fit list above
  • Inspect the existing burner door and its sealing face for damage before ordering
  • Check the part number BI1663103 against the manufacturer's parts list for your appliance
  • Fitting should be carried out by a Gas Safe registered engineer
