Lochinvar & A.O. Smith 100208764 Gasket
As a veteran HVACR technician, you know that a compromised seal on a high-efficiency blower assembly is a recipe for pressure switch faults and reduced combustion efficiency. The Lochinvar & A.O. Smith 100208764 Gasket is a precision-engineered 1/32-inch blower motor gasket designed specifically for a critical interface between the combustion blower and the burner mounting plate. Manufactured as an authentic OEM boiler part, this replacement blower gasket ensures a gas-tight seal, preventing the "hunting" or erratic airflow that often leads to nuisance lockouts in condensing boilers and high-recovery water heaters. Whether you are performing a teardown on a Lochinvar Knight or an A.O. Smith Cyclone unit, replacing this HVAC blower gasket is standard protocol to maintain the integral pressurized housing. It is a direct boiler maintenance part for several high-demand models, including the AWN200PM, AWN201PM, and CDN100 series, as well as the OK 211 and AW199. Measuring approximately 3.3" x 3.3", this lightweight yet durable Lochinvar burner gasket provides the resilience needed to withstand the thermal cycling typical of modern modulated firing rates, ensuring your customers' systems stay online and peak-efficient.
Key Benefits- Airtight Combustion Seal: Eliminates air leaks at the blower housing to prevent pressure switch vibration and ignition failure.
- Exact OEM Compatibility: Engineered by Lochinvar & A.O. Smith to match the original factory footprint for a drop-in 1/32-inch fit.
- High-Temperature Durability: Constructed from specialized materials that resist degradation under the constant thermal stress of high-efficiency combustion.
- Efficiency Restoration: Maintains the specific air-to-fuel ratio required for low-NOx performance and optimal fuel economy.
- When should this gasket be replaced? It is recommended to replace the 100208764 whenever the blower is removed for heat exchanger cleaning or motor inspection, as the original 1/32-inch material often compresses or tears upon disassembly.
- Does this gasket fit the Lochinvar Knight series? Yes, it is compatible with various Knight (AWN/WAN) and Shield (SNR/SLR) models, as well as A.O. Smith commercial water heaters utilizing this specific blower flange.
- Can I use RTV silicone instead of this gasket? High-temperature RTV is not a professional substitute for a precision-cut OEM gasket in combustion applications, as it can seep into the blower housing and interfere with fan balance or sensor accuracy.
