Baxi Duo Tec 24 28 33 40 HE & HE A Combustion Chamber Gasket 5114755

Product Overview

The Baxi Combustion Chamber Gasket 5114755 is a sealing component designed for use within selected Baxi heating systems.

The combustion chamber gasket forms a high-temperature seal between the combustion chamber and surrounding components, helping to maintain an airtight combustion chamber during boiler operation. A correctly fitted gasket is essential for supporting safe and efficient combustion while preventing the escape of combustion gases.

Technical Insight & Common Servicing Requirements

The combustion chamber gasket is subjected to repeated heating and cooling cycles during normal boiler operation. Over time, the gasket may become compressed, brittle, or damaged, reducing its sealing performance.

Typical reasons for replacement include:

• Damage or deterioration during servicing
• Signs of wear, cracking, or compression
• Maintaining a secure combustion chamber seal after disassembly
• Preventing leakage of combustion gases
• Routine replacement in accordance with manufacturer servicing procedures

Replacing a worn or damaged combustion chamber gasket helps maintain the integrity of the combustion chamber and supports the safe operation of the boiler.
