Our Expert's Opinion
"Ensures an airtight seal for safe combustion. Fits multiple condensing boiler models."Saunier Duval 20195512 Combustion Chamber Cover Gasket – Genuine Boiler Seal Replacement
The Saunier Duval 20195512 is a genuine combustion chamber cover gasket designed to create and maintain an airtight seal between the combustion chamber and its cover on a wide range of Saunier Duval condensing boilers. This seal is critical to the safe and efficient operation of the appliance, ensuring that combustion gases remain fully contained within the sealed chamber during operation.
In modern condensing boilers, the combustion process takes place within a room-sealed environment. The gasket plays a fundamental role in preserving this sealed system by preventing the escape of flue gases and maintaining the correct internal pressure conditions required for efficient combustion. Any compromise in this seal, whether through wear, compression fatigue, or damage during servicing, can lead to reduced boiler performance, potential fault codes, or, in more serious cases, unsafe operation.
Manufactured to precise OEM specifications, this gasket is designed to withstand the high temperatures and chemical exposure associated with continuous combustion cycles. Over time, however, even high-quality sealing materials degrade. Heat cycling causes the gasket to harden and lose elasticity, reducing its ability to form a reliable seal when the combustion chamber is reassembled after servicing.
For this reason, it is widely regarded as best practice to replace the combustion chamber gasket whenever the chamber is opened for inspection, maintenance, or repair. Reusing an old gasket can lead to incomplete sealing, increasing the likelihood of air leaks or flue gas escape, which can affect combustion efficiency and trigger safety shutdowns.
Key Features:
Part Number: 20195512
Type: Combustion chamber cover gasket
Function: Provides airtight seal for sealed combustion system
Genuine Saunier Duval spare part – manufactured to OEM standards
Heat and chemical resistant material for long-term durability
Essential safety component for maintaining correct combustion conditions
Must be fitted by a Gas Safe registered engineer
Compatible Boilers Include:
Commonly used across multiple Saunier Duval condensing boiler ranges, including:
Saunier Duval Micra Condensing range
Saunier Duval Thema Condens and Themafast Condens range
Saunier Duval Thesi Condensing range
Saunier Duval Isotwin Condens range
Saunier Duval Spazio and Eura condensing models
Compatibility can vary depending on model variant, serial number, and production batch.
Always confirm compatibility using the appliance data plate and manufacturer parts list before ordering. If unsure, consult the Saunier Duval technical support team.
Why Replace the Gasket During Servicing:
The combustion chamber gasket is a single-use sealing component. Once compressed and exposed to sustained heat, it does not reliably return to its original shape. Reinstalling an existing gasket after removing the combustion cover significantly increases the risk of an imperfect seal.
Routine replacement ensures:
A secure, airtight combustion chamber
Stable and efficient burner performance
Reduced risk of flue gas leakage
Compliance with manufacturer servicing standards
Replacing this low-cost component during maintenance helps prevent far more costly issues, including repeat callouts and safety-related shutdowns.
