Lochinvar & A.O. Smith 100093993 Burner Assembly
The Lochinvar & A.O. Smith 100093993 Burner Assembly is a high-performance NAT Final Burner Assy engineered for precise combustion in commercial water heaters and hydronic boilers. This genuine OEM replacement part is critical for restoring the stoichiometric air-fuel ratio, ensuring a stable, concentrated flame that maximizes heat transfer while minimizing NOx emissions. Fabricated with high-grade, heat-resistant materials, the 100093993 burner survives the rigorous thermal cycling common in Lochinvar Knight and A.O. Smith Vertex series units. For a veteran contractor, this is a "drop-in" solution that eliminates the risk of flame failure codes or improper ignition sequences associated with non-spec components. Whether you are addressing soot accumulation in the combustion chamber or a damaged natural gas burner head, this assembly provides the exact factory tolerances required to meet the original equipment’s BTU input ratings and operational efficiency. Maintain the integrity of your high-efficiency system with this OEM burner assembly to ensure reliable hot water delivery and peak system performance.
- Natural Gas Compatibility: Engineered specifically for NG Natural Gas configurations to maintain factory-certified combustion safety.
- OEM Precision: Guaranteed genuine A.O. Smith and Lochinvar part ensures internal ignition system components align perfectly with the heat exchanger.
- Emissions Control: The advanced burner design promotes a clean burn, reducing carbon buildup and extending the service interval of the flame sensor.
- System Reliability: Replaces worn or warped burner ports to prevent "clicking" or "sputtering" sounds during the ignition process.
Common Questions
Is this burner assembly compatible with my specific boiler or water heater?
The 100093993 burner assembly is designed for specific A.O. Smith and Lochinvar models, including several Knight and Knight XL series. Always verify compatibility using your unit's serial number before installation.
What are the signs that my burner assembly needs to be replaced?
Technicians should look for visible soot buildup, frequent flame failure error codes, localized hotspots on the burner face, or uneven flame patterns that lead to reduced thermal efficiency.
How do I ensure a clean combustion after installing the new assembly?
After installing the natural gas burner, it is recommended to perform a full combustion analysis at both low and high fire to confirm the CO2 and O2 levels match the manufacturer's nameplate specifications.
