What it is
The GASKET BURNER is a sealing gasket supplied by Potterton for the burner assembly of Potterton Commercial boilers. It sits at the burner mounting face and seals the joint between the burner and the combustion chamber, preventing leakage of combustion products at that interface. It is listed under gas boiler spares as part number 5142122.
Signs this part needs replacing
