Lochinvar & A.O. Smith 100111824 Burner/Sleeve Assembly

The Lochinvar & A.O. Smith 100111824 Burner/Sleeve Assembly is an essential OEM replacement kit engineered for high-recovery commercial water heaters and industrial boilers. As a direct replacement for the legacy 211941-000, this assembly integrates a precision-engineered burner head with a durable sleeve designed to optimize the combustion cycle. By facilitating an airtight fuel-to-air mixture before ignition, it ensures stable flame support and enhanced heat transfer across the heat exchanger surface. This natural gas burner assembly is built to original manufacturer specifications to maintain consistent terminal velocity and prevent premature oxidation or warping under intense thermal loads. For contractors performing scheduled maintenance or emergency HVAC furnace repairs, this kit provides the technical tolerances required to ensure low-emission operation and peak thermal efficiency in both Lochinvar and A.O. Smith systems.

• Direct Compatibility: Engineered as the exact OEM replacement for 211941-000, ensuring a drop-in fit without field modifications.
• Enhanced Combustion: Optimized burner/sleeve assembly design promotes more complete combustion for reduced carbon buildup.
• Industrial Durability: Constructed with high-grade materials to withstand the rigorous cycling and high temperatures of commercial heating equipment.
• Precision Air-Fuel Mixing: Precisely calibrated ports ensure the correct stoichiometric ratio for reliable ignition and stable flame patterns.

Is the 100111824 burner assembly compatible with both Lochinvar and A.O. Smith units?
Yes, because Lochinvar and A.O. Smith utilize many shared components in their high-efficiency commercial lineups, this part is the OEM burner kit specified for several large-capacity models from both brands.

Will this assembly help resolve "rumbling" or unstable flame issues?
Often, yes. Burner sleeves that have warped or accumulated heavy scale can cause turbulent gas flow. Replacing the worn component with this genuine burner/sleeve assembly restores the uniform flame required for quiet, efficient operation.

What is included in this kit?
The 100111824 kit includes the primary burner head and the protective sleeve assembly required for a complete professional installation.
