Lochinvar & A.O. Smith 100135309 Burner
The Lochinvar & A.O. Smith 100135309 Burner is a critical combustion component designed for high-efficiency hydronic systems. This OEM replacement burner is engineered specifically for use in Knight (KBN/AWN/WB) and Armor/Shield (SNR) boiler and water heater models, including the 200 and 210 series. As a radial fire burner, it facilitates a precise fuel-to-air mixture for clean, stable combustion across varying firing rates. Integrating a 100135309 burner assembly ensures that the system maintains its original BTU/hr input and energy density, which are vital for meeting commercial and residential heating demands. This kit includes the necessary high-temperature burner gasket, providing a robust seal that prevents combustion gas leakage and stabilizes internal pressure. For service technicians, utilizing genuine Lochinvar parts is essential to resolve common "Ignition Failure" or "Rough Operation" fault codes often caused by degraded burner mesh or debris buildup. Replacing a fouled burner with this factory-spec unit restores optimal thermal efficiency and reduces nitrogen oxide emissions.
Key Benefits- Direct Compatibility: Specifically designed for Knight KBN and Armor SNR210 heating boilers, ensuring a precise mechanical fit.
- Enhanced Combustion Efficiency: Features a radial fire burner design that optimizes gas-air mixing and increases energy density.
- Leak Prevention: Includes the technical burner gasket required to create a firm, airtight seal against the heat exchanger flange.
- Reliable Ignition: Alleviates common "Ignition Failure" issues by providing a new, clean surface for flame sensing and propagation.
- OEM Performance: Maintains the factory-calculated 150,000 to 399,000 BTU/hr input ratings for system-specific applications.
What boiler models are compatible with this burner?
The 100135309 is verified for use with Lochinvar Knight (Models KBN, AWN, WB) and A.O. Smith Armor/Shield (SNR210) units. Always verify your specific model number against the manufacturer’s parts manual.
Does this assembly include the necessary seals?
Yes, this burner replacement kit comes with the required gasket to ensure a safe, secure installation and to prevent bypassed combustion air.
Can this burner resolve "Ignition Failure" errors?
If the existing burner mesh is corroded, clogged with plastic shavings, or thermally deformed, it can cause flame sensing current drops. Installing a new 100135309 assembly often restores consistent flame signal and system uptime.
