What it is
The Biasi BI1253102 is an air-gas gasket used on Biasi gas boilers. It seals the air-gas circuit joint, preventing leakage of gas and air at the mating face. It is listed under Orings, Washers & Gaskets within gas boiler spares.
Signs this part needs replacing
- A smell of gas or combustion products around the air-gas joint
- Visible cracking, hardening, flattening or deformation of the gasket
- Soot staining or discolouration at the sealing face
- Combustion readings outside the expected range after servicing
- The gasket is disturbed or damaged when the joint is opened
Before you order
- Confirm your boiler model matches one of the fitments listed above
- Check the gasket position on the air-gas joint against the old part before removal
- Inspect the mating faces for corrosion or pitting that could prevent a seal
- Have the boiler recommissioned and combustion checked after fitting
