Lochinvar & A.O. Smith 100208061 Baffle Insulation
The Lochinvar & A.O. Smith 100208061 Baffle Insulation is a critical OEM replacement part designed for high-efficiency hydronic systems. This 182.5mm divider plate insulation is engineered specifically for Knight XL heating boilers and high-recovery water heaters, ensuring precise thermal separation within the combustion chamber. As a veteran-grade HVAC boiler component, it functions to direct flue gases effectively while protecting the heat exchanger assembly from excessive thermal stress. Maintaining the integrity of the combustion chamber insulation is vital for preventing heat loss and ensuring the unit meets its AFUE rating. This 182.5mm baffle insulation (formerly referenced as FIB2167) provides a precise fit for KB, AW, and WB series models, mitigating the risk of uneven heating and potential cabinet overheating. When performing a teardown or heat exchanger cleaning, inspecting this baffle for degradation is a standard best practice to ensure long-term operational reliability and combustion stability.
Key Benefits:- Precise Geometry: Specifically sized at 182.5mm for a secure fit within Knight XL KB399-800 series boilers and compatible A.O. Smith units.
- Thermal Protection: Functions as a high-density insulation divider plate to minimize heat loss and improve energy transfer efficiency.
- Direct OEM Replacement: Replaces legacy part numbers FIB2167 and 100145494, ensuring full compatibility with existing burner mounting hardware.
- Durability: Constructed from high-temperature resistant materials designed to withstand thousands of heating cycles without structural fatigue.
- Which models are compatible with this baffle insulation? This part is specifically utilized in Lochinvar Knight XL (KB81-286, KB399-800), AW, and WB series boilers, as well as select A.O. Smith commercial water heaters.
- Does this include the burner gasket? No, this is the 182.5mm baffle insulation only. It is recommended to replace the burner mounting gasket concurrently when servicing the combustion chamber.
- Why is my old baffle insulation crumbling? Over time, exposure to high flue gas temperatures and condensate can cause ceramic fiber or mineral-based insulation to degrade. Replacement is necessary to prevent bypass and maintain cabinet safety.
