Lochinvar & A.O. Smith 100135304 Burner

The Lochinvar & A.O. Smith 100135304 Burner is a precision-engineered main burner assembly designed for high-output commercial heating applications. Specifically built for the Copper-Fin II series, including models ranging from 992 to 2072, this component is rated for 900 KBTU/HR to ensure consistent combustion and thermal transfer. Measuring 2-1/8 inches in diameter and 23-1/4 inches in length, the 100135304 burner tube utilizes a durable flange-mount design (2-5/8 x 3 inches) to maintain a secure seal within the combustion chamber. As a genuine OEM replacement part, it eliminates the calibration issues often found with aftermarket alternatives, ensuring the proper fuel-to-air ratio is maintained across the entire modulation range. Whether you are servicing a Lochinvar Knight fire tube boiler or a large-scale A.O. Smith commercial water heater, this burner provides the structural integrity required to withstand high-flame temperatures and prevent premature warping or clogging in demanding hydronic environments.

• Optimized Combustion: Engineered for 900 KBTU/HR capacity to maximize fuel efficiency and reduce carbon output in Copper-Fin II systems.
• Exact Dimensional Match: The 23-1/4 inch length and 2-1/8 inch diameter ensure seamless integration into existing burner racks without field modifications.
• OEM Reliability: Replacing worn burners with genuine Lochinvar 100135304 parts protects the heat exchanger from hot spots and uneven heat distribution.
