Lochinvar & A.O. Smith 100233338 Burner

The Lochinvar & A.O. Smith 100233338 Burner is a critical combustion component engineered for high-efficiency gas-fired boilers and water heaters. As a direct OEM replacement burner for the obsolete Lochinvar BNR2902, this part is designed to maintain precise atmospheric or pre-mix combustion across various residential and commercial heating systems. Constructed from premium-grade materials to withstand high thermal stress, it ensures stable flame patterns and optimal fuel-to-air ratios, which are essential for reducing emissions and maximizing AFUE ratings. For service technicians, this genuine Lochinvar burner assembly is the standard choice for restoring system integrity in Lochinvar Knight and A.O. Smith water heaters. Integrating this HVAC burner replacement during routine maintenance prevents common issues like irregular ignition or carbon buildup, ensuring the heat exchanger operates at peak performance. This durable heating system component is built to the exact specifications of the original equipment, facilitating a seamless fit and reliable long-term operation in demanding hydronic applications.

• OEM Compatibility: Serves as the official replacement for the 100233338 and BNR2902 parts, ensuring perfect alignment with original manifold and orifice technical specs.
• Combustion Efficiency: Optimized for stable flame characteristics, helping to maintain high energy efficiency and lower operational costs.
• Rugged Construction: Built with high-temperature resistant alloys to prevent warping and degradation under continuous firing cycles.
• Direct Fitment: Standardized dimensions allow for a rapid swap-out, reducing labor time during emergency boiler repairs.

• Is this burner compatible with LP conversion kits? Yes, this burner assembly can typically be used in both natural gas and liquid propane configurations, provided the correct orifices and conversion kits are utilized per the manufacturer's manifold pressure requirements.
• How do I know if my current burner needs replacement? Look for signs of "flame rollout," heavy soot accumulation, or physical cracks in the burner ribbon. These issues often lead to inefficient combustion and potential safety switch trips.
• Does this include the igniter or flame sensor? This part number generally refers to the main burner assembly. We recommend inspecting your existing igniter and flame rod, as they may need to be ordered separately if they show signs of significant wear.
