Lochinvar & A.O. Smith 100208102 Gasket
As a veteran technician, you know that maintainting a pressure-tight seal on high-efficiency equipment is non-negotiable for both performance and safety. The Lochinvar & A.O. Smith 100208102 Gasket (formerly GKT2058) is the industrial-grade solution required to effectively seal the critical junction between the burner assembly and the blower fan. Designed for high-output condensing boilers and water heaters, this burner fan gasket prevents the leakage of combustion byproducts into the cabinet while ensuring precise fuel-to-air ratio stability. Inconsistent combustion or a "whistling" fan housing is often a direct result of a degraded OEM boiler gasket. By utilizing this 0.09lb precision-cut component, you guarantee a high-efficiency combustion seal that withstands the thermal cycling common in commercial water heater repair. Whether you are performing an annual teardown or a Lochinvar boiler maintenance overhaul on FBL or PBL series units, replacing this seal is a standard best practice to prevent carbon monoxide leakage and maintain peak system modulation.
Key Benefits for the Contractor:- Universal Compatibility: Replaces legacy part numbers GKT2058, 100146477, and GKT2058K for seamless integration.
- Superior Thermal Resistance: Engineered to maintain its structural integrity under the high-temperature demands of commercial burner plates.
- Optimized Airflow: Eliminates bypass air leaks that cause nuisance flame failures and inefficient heat exchange.
- Exact Fitment: Eliminates the need for messy RTV or "make-it-fit" field solutions, saving time during HVAC part replacement.
Which models are compatible with this specific burner/fan gasket?
This gasket is a direct fit for several high-efficiency series including the Lochinvar Knight (FBL/FBN 3500) and Copper-Fin II (PBL/PBN 1501-2001) models. Always verify your specific model and serial number against the manual to ensure the 100208102 is the correct exhaust seal configuration.
Can I reuse the old gasket if it looks intact?
In a professional setting, we never recommend reusing a burner gasket. Once the assembly is torqued down, the material compresses to form a seat. Reusing it often leads to micro-leaks that can damage the burner door or cause erratic sensor readings.
What are the signs that this gasket is failing?
Look for soot marks around the fan-to-burner flange, a distinct smell of flue gases in the mechanical room, or high CO levels during a combustion analysis. If you see signs of "frying" or hardening of the current seal, it is time for a replacement.
