Lochinvar & A.O. Smith 100233703 Gasket

The Lochinvar & A.O. Smith 100233703 Gasket is a critical OEM replacement part engineered specifically for high-efficiency commercial boilers and water heaters. As a direct-fit Air Shroud Gasket, this component ensures an airtight seal between the air shroud and the burner assembly, preventing combustion air bypass and maintaining the precise fuel-to-air ratio required for peak thermal efficiency. Constructed from high-grade, heat-resistant sealing material, this gasket is built to withstand the rigorous cycling and thermal expansion typical of light commercial and industrial hydronic systems. This part is a verified replacement for legacy part numbers GKT2080K, 100146494, and GKT2080. Field technicians should verify the integrity of this seal during every preventative maintenance call to prevent CO leakage or erratic burner performance. Designed for seamless integration with units like the Lochinvar Knight and various A.O. Smith models, it provides the HVAC system reliability professionals demand for pressurized combustion environments.

Key Benefits:

• Optimized Combustion: Eliminates air leaks at the shroud interface to ensure consistent burner firing and stable flame signals.
• Broad Compatibility: Engineered for use in Lochinvar AWH0500NPM, AWN501PM, OKL501, and OKN501 models.
• Durable Construction: Manufactured by Lochinvar & A.O. Smith to meet exact factory tolerances for pressure-tight sealing.
• Direct OEM Fit: Simplifies installation by serving as a 1:1 replacement for 100233703 and associated legacy cross-references.

Common Questions:

• What symptoms indicate a failing air shroud gasket? Technicians often observe irregular combustion noise, reduced CO2 readings, or visual soot buildup around the air intake housing.
• Is this part compatible with non-condensing units? This specific gasket is designed for high-efficiency condensing boilers and water heaters where air-to-fuel precision is paramount.
• Can I reuse the existing gasket for burner service? We recommend replacing the 100233703 gasket whenever the air shroud is removed to ensure a positive seal since the material compresses over time.
