Lochinvar & A.O. Smith 100135269 Burner
The Lochinvar & A.O. Smith 100135269 Burner is a precision-engineered 100% OEM replacement for high-efficiency condensing boilers, specifically designed for WH285 and WH399 models. As a critical component in the combustion assembly, this burner ensures an optimal air-to-fuel ratio, supporting the high-turndown ratios found in the Lochinvar Knight and A.O. Smith boiler series. Built to industrial-grade standards, the assembly is compatible with both natural gas and propane applications, providing the necessary thermal resistance to withstand the high-intensity flame patterns of 399K BTU systems. This unit includes a pre-installed burner gasket to guarantee a hermetic seal against the heat exchanger plate, preventing flue gas leakage and maintaining consistent manifold pressure. For field technicians, this part is essential for resolving common boiler lockout codes related to flame rectification or cracked burner ceramic, ensuring the heat exchanger remains free of soot and debris during heavy firing cycles.
Key Benefits- Direct OEM Compatibility: Perfectly replaces the burner assembly in Lochinvar WHB399N, WHL400, WHN399, and WHN400 units without field modification.
- Optimized Combustion: Engineered to facilitate precise gas-air mixing, which maximizes heat transfer and maintains high-efficiency performance in condensing environments.
- Sealing Integrity: Includes high-temperature gaskets to ensure a safe, leak-proof installation between the blower assembly and the combustion chamber.
- Dual Fuel Versatility: Certified for use in both LP and NG configurations, providing flexibility for various job site fuel requirements.
What are the symptoms of a failing 100135269 burner?
Contractors often report "rumbling" or "pulsating" during the ignition phase, soot buildup on the heat exchanger coils, or persistent "No Flame Detected" faults when the burner mesh becomes warped or clogged with atmospheric contaminants.
Does this burner include the required mounting gaskets?
Yes, this 100135269 burner assembly comes with the necessary gaskets to ensure a proper seal during the reconditioning of the burner door, protecting the inducer fan and gas valve assembly from back-pressure.
Is this part suitable for both Knight and XL series boilers?
Yes, while commonly used in the Knight series, it is cross-referenced for use across A.O. Smith and Lochinvar commercial 399 units. Always verify the Part ID 779109 on your existing technical drawing before installation.
