What it is
This is a combustion chamber gasket manufactured by Biasi, carrying the part number BI1503102. It seals the joint at the combustion chamber on Biasi Advance gas boilers, keeping the products of combustion contained within the appliance and the flue path. The gasket forms part of the combustion circuit and must be sound for the boiler to operate safely.
Signs this part needs replacing
- Visible cracking, hardening or brittleness of the gasket material
- Soot staining or dark streaks around the combustion chamber joint
- Combustion readings drifting outside the expected range for the appliance
- A smell of combustion products in the vicinity of the casing
- Gasket flattened or compressed so it no longer seals when the chamber is reassembled
Before you order
- Confirm the boiler model and GC number against the manufacturer's parts list
- Check the gasket profile and seating face on the appliance before fitting
- Combustion chamber work must be carried out by a competent, gas-registered engineer
- Replace the gasket whenever the combustion chamber cover is disturbed
