What it is

The Biasi BI1503105 is an air-gas gasket used on Biasi Advance series boilers. It seals the air-gas pathway at the point where the gasket is fitted, preventing leakage of gas and maintaining correct combustion air delivery. It is a serviceable component intended for replacement during maintenance or repair of the appliance.

Signs this part needs replacing

  • A smell of gas around the air-gas connection or gasket seating area
  • Visible cracking, hardening, flattening or deformation of the gasket material
  • Soot deposits, unstable flame or poor combustion readings traced to the air-gas joint
  • Whistling or unusual noise from the air-gas pathway
  • Gasket damage found during routine servicing or after the joint has been disturbed

Before you order

  • Confirm your appliance model against the fit list above before ordering
  • Check the existing gasket's part number or position to confirm BI1503105 is the correct item
  • Inspect the mating surfaces for corrosion or damage, as these may also need attention
  • Have the appliance reassembled and checked by a competent heating engineer after fitting
