Lochinvar & A.O. Smith 100208095 Burner Gasket

The Lochinvar & A.O. Smith 100208095 Burner Gasket is a critical OEM replacement part designed to maintain the pressure vessel integrity of high-efficiency condensation boilers and water heaters. Engineered for high-temperature resilience, this burner flange gasket ensures a gas-tight seal between the burner assembly and the combustion chamber, preventing hazardous flue gas leakage and optimizing thermal transfer. As a direct crossover for the Lochinvar GKT2103, this component features precise tolerances to withstand the intense thermal cycling common in commercial boiler maintenance.

For technicians performing a teardown or heat exchanger cleaning, replacing the 100208095 is a standard protocol to prevent nuisance flame failure codes and ensure HVAC combustion efficiency. The specialized material composition resists degradation from corrosive condensate and high-BTU firing rates. Utilizing genuine Lochinvar parts like this gasket ensures that the equipment operates within original factory specifications, maintaining the safety and performance levels required for demanding mechanical room environments.

• High-Temperature Durability: Specifically formulated to resist thermal breakdown in the combustion zone.
• Precision Fit: Identical to GKT2103, ensuring a perfect seal without the need for additional sealants.
• Enhanced Safety: Critical for preventing the escape of carbon monoxide and other combustion byproducts into the mechanical space.
• Optimized Performance: Maintains the correct air-to-fuel ratio by eliminating vacuum leaks at the burner interface.

Is the 100208095 a direct replacement for the GKT2103?
Yes, the 100208095 is the current manufacturer-designated part number and is functionally identical to the discontinued Lochinvar GKT2103. It requires no modifications for installation.

Why is it necessary to replace the burner gasket during annual maintenance?
During boiler service, the compression set of the original gasket is disturbed. Reusing a compressed gasket can lead to improper sealing, resulting in localized overheating or airflow fluctuations that trigger "No Flame" errors.

What models are compatible with this burner gasket?
This gasket is commonly used across various A.O. Smith and Lochinvar platforms, including specific series of high-efficiency water heaters and boilers where a circular burner-to-door seal is required. Always verify the specific HVAC part compatibility with your model's unit serial number.
