Lochinvar & A.O. Smith 100135293 Burner Kit

The Lochinvar 100135293 Burner Kit is a critical OEM replacement component engineered for high-efficiency commercial water heaters, specifically compatible with A.O. Smith BTH 120-250 and Lochinvar AWN/AWL 151-286 series models. This pre-mixed combustion burner ensures precise gas-to-air ratios, maintaining thermal stability and reducing NOx emissions across variable firing rates. As a direct-fit replacement burner, it resolves common combustion issues such as irregular flame patterns, carbon buildup, and ignition failure. The assembly includes the necessary burner gaskets and mounting hardware required for a pressure-tight seal within the heat exchanger. This stainless steel burner is designed to withstand high-temperature cycling in demanding hydronic applications. Field technicians should verify the gas valve manifold pressure and blower speeds after installation to ensure the 100135293 burner kit operates at peak efficiency. Utilizing genuine Lochinvar replacement parts maintains the integrity of the original equipment's venting and combustion safety protocols.

• Precise Flame Distribution: Engineered for high-efficiency water heaters to provide uniform heat transfer across the primary heat exchanger.
• Corrosion Resistance: Constructed with industrial-grade stainless steel to prevent premature oxidation and metallurgical fatigue in condensing environments.
• Optimized Signal Strength: Ensures consistent flame rectification signals to the integrated control board, reducing nuisance lockouts.
• Simplified Maintenance: This complete burner assembly reduces downtime by providing all critical components for a standard combustion overhaul.

Common Questions

What are the symptoms of a failing burner kit in BTH units?
Common indicators include delayed ignition, excessive resonance during firing, or "sooting" visible through the sight glass. Monitoring for E02 ignition failure codes can also signal that a Lochinvar 100135293 replacement is necessary.

Is this burner compatible with both Natural Gas and Propane units?
This 100135293 burner kit is generally used in Natural Gas configurations. If converting to LP, specific orifice changes and regulator adjustments must be performed according to the manufacturer's technical manual to prevent hazardous combustion levels.

Does this kit include the mounting gaskets and igniter?
This kit is the primary burner head assembly. While it includes the necessary mounting gaskets for the burner flange, technicians should inspect the hot surface igniter and flame sensor separately to ensure the entire ignition sequence is optimized.
