Lochinvar & A.O. Smith 100109226 Burner

The Lochinvar & A.O. Smith 100109226 Burner is a critical LP main burner assembly designed for high-performance commercial and residential water heating systems. Engineered for LP (Liquid Propane) applications, this replacement burner head ensures precise fuel-to-air ratios, maintaining clean combustion and preventing common soot buildup issues. This SKU serves as a direct OEM replacement part, replacing legacy numbers 182730-000 and 9003422005. The inclusion of a high-temperature door gasket ensures a pressure-tight seal at the combustion chamber interface, which is vital for preventing flue gas leakage and maintaining thermal efficiency in condensing water heaters and storage tanks. This assembly is built to withstand the intense cycling demands of commercial service, offering long-term reliability for HVAC repair and preventative maintenance. When troubleshooting water heater ignition failure or poor flame signals, replacing the full burner and gasket assembly is a standard best practice to restore the unit to factory-specified performance levels. Verify your existing manifold pressure before finishing the installation to ensure optimal burner operation.
