Lochinvar & A.O. Smith 100233594 Burner Gasket

The Lochinvar & A.O. Smith 100233594 Burner Gasket is a critical high-temperature seal engineered for high-efficiency condensing boilers and water heaters. As a direct OEM replacement part for GKT2062 (also indexed as GKT2062K and 100146481), this component ensures a gas-tight interface between the burner assembly and the combustion chamber. Maintaining a precise seal is vital for preventing flue gas leakage and ensuring optimal combustion efficiency in commercial and residential hydronic systems. This burner gasket is specifically designed to fit Lochinvar Knight and Copper-Fin models, including the KBN601 through KBN801 series, as well as AWN and OKN units. Fabricated from durable, heat-resistant materials, it withstands the thermal cycling common in HVACR heating applications. Replacing a degraded gasket during routine maintenance is essential to prevent CO leakage and maintain the structural integrity of the heat exchanger assembly.

• Precise OEM Compatibility: Engineered as an exact replacement for GKT2062, ensuring a perfect fit for Lochinvar & A.O. Smith burner assemblies.
• High-Temperature Durability: Constructed to resist degradation from high-intensity thermal exposure within the combustion zone.
• Enhanced System Safety: Critical for preventing the escape of dangerous combustion byproducts into the mechanical room.
• Optimized Performance: Maintains the internal pressure required for efficient fuel-to-air ratios and peak boiler efficiency.

Which Lochinvar models use the 100233594 burner gasket?
This gasket is widely used in the Knight XL, Copper-Fin II, and Power-Fin series, specifically covering many 601, 701, and 801 MBH input models. Always verify your specific model and serial number against the 100233594 part ID.

Can I reuse the old burner gasket if it looks intact?
It is standard trade practice to replace the burner gasket whenever the burner is removed for inspection. Once the material is compressed and heat-cycled, it may not re-seal effectively, risking HVAC system leaks.

Is this part interchangeable with GKT2062?
Yes, the 100233594 is the current manufacturer part number and is identical in form and function to the older GKT2062 and 100146481 designations.
