Potterton Door Seal S17000198

This is the Potterton door seal, supplied under part number S17000198, for Potterton Commercial gas boilers. It seals the joint between the combustion chamber door and the boiler body, helping to contain the combustion process and prevent leakage of flue products at the door face. The seal forms part of the door assembly and is replaced as the existing gasket degrades.

• Visible cracking, hardening or flattening of the seal material
• Signs of leakage or staining around the combustion chamber door face
• The door gasket breaking up or separating when the door is opened for service
• Combustion readings drifting or proving difficult to set after the door is refitted
• The seal no longer sitting correctly in its locating groove

• Confirm the boiler model and the number of sections against the fit list above
• Check the existing door seal against part number S17000198
• Inspect the door face and fixings while the door is open, as these may also need attention
• Confirm the door seal is the only gasket required for the job before ordering
