What it is

The Biasi BI1663101 is a lip gasket for the combustion chamber on Biasi condensing appliances. It seals the joint at the combustion chamber lip, maintaining a gas-tight and heat-resistant seal at that face. It is used across the Basica COND and Rinnova Adaptive ranges.

Signs this part needs replacing

  • Visible cracking, hardening or flattening of the gasket material
  • Soot staining or heat discolouration around the combustion chamber lip
  • Signs of leakage at the chamber joint during a flue gas analysis or combustion check
  • Gasket damage found when the combustion chamber is opened for servicing
  • The gasket does not seat correctly or has been disturbed during previous work

Before you order

  • Confirm the appliance model and GC number against the fitment list above
  • Check the existing gasket for part number marking or compare its profile and dimensions
  • Inspect the combustion chamber lip for distortion or corrosion before refitting
  • Follow the manufacturer's servicing instructions for combustion chamber access and gasket renewal
