Lochinvar & A.O. Smith 100265719 Burner Assembly

The Lochinvar & A.O. Smith 100265719 Burner Assembly is a precision-engineered Natural Gas burner assembly designed for high-efficiency combustion in commercial and residential water heaters and heating systems. As a critical maintenance and repair component, this OEM burner assembly ensures a controlled gas-air mixture, facilitating optimal heat transfer while maintaining low emission levels. Built with a durable N3 G50T40 Al Ext aluminum oxide or specialized alloy construction, it is specifically configured for NG (Natural Gas) applications and serves as a direct replacement for A.O. Smith, State, and American Water Heater models. This assembly typically includes the burner head, precision orifices, and necessary mounting points for integration with the ignition system and flame sensors. For contractors performing HVACR burner replacement, verifying the model and serial number is essential to ensure unit compatibility and safe operation within the pressurized combustion chamber.

• Precision Orifice Design: Optimized for Natural Gas to ensure consistent flame patterns and efficient fuel utilization.
• OEM Compatibility: Fits specific Lochinvar and A.O. Smith water heater models, including many 40-gallon and 50-gallon tank units.
• Durable Construction: Engineered with high-grade materials to withstand thermal stress and prevent premature corrosion in the combustion zone.
• Improved System Reliability: Restores factory-spec performance for pilots and hot surface igniters, reducing nuisance lockouts and service calls.

Is this burner assembly compatible with Propane (LP) units?
No, the 100265719 is specifically calibrated for Natural Gas (NG) operations. Using this assembly with Liquid Propane without proper conversion components is unsafe and not recommended.

Does this assembly include the pilot and flame sensor?
This part primarily consists of the main burner assembly. Technicians should inspect existing ignition components and flame sensors during installation; replacing these concurrently is a best practice for long-term system stability.

How do I verify if this fits my water heater?
Compatibility is determined by the specific model and serial number of your Lochinvar or A.O. Smith unit. Always reference the factory parts list or contact a specialist with your data plate information to ensure an exact match.
