Lochinvar & A.O. Smith 100110383 Assembly

The Lochinvar & A.O. Smith 100110383 Assembly is a precision-engineered main burner with pilot bracket designed for high-performance residential and commercial natural gas water heaters and boilers. As a critical OEM replacement part, this burner assembly ensures a stable, clean combustion process, which is essential for maintaining strict thermal efficiency and reducing carbon buildup within the heat exchanger. The integrated pilot bracket is factory-aligned to provide consistent flame propagation, ensuring the main burner ignites reliably under specific manifold pressures. Compatible with select BTRC water heater models and specialized Lochinvar hydronic systems, the 100110383 replaces legacy part numbers 9005292205 and 193873. For contractors, installing this genuine HVAC pilot burner assembly eliminates the common fitment issues associated with universal alternatives, preserving the original equipment's combustion parameters and safety certifications. Its durable construction is built to withstand the high-temperature environment of the combustion chamber, providing reliable service life in heavy-cycle applications.

• Precise Gas Regulation: Specifically calibrated for natural gas systems to ensure optimal fuel-to-air ratios and peak efficiency.
• OEM Alignment: The factory-welded pilot bracket ensures the pilot flame is perfectly positioned for rapid, safe main burner ignition.
• Direct Compatibility: Engineered as a drop-in replacement for A.O. Smith and Lochinvar units, reducing labor time during maintenance calls.
• Thermal Stability: Constructed from high-grade materials to prevent warping or corrosion during prolonged firing cycles.

Is the 100110383 compatible with propane (LP) units?
This specific assembly is typically configured for natural gas; always verify the orifice size and manifold pressure requirements for your specific model before installation.

Does this assembly include the pilot tubing and electrode?
The 100110383 is a burner assembly with the pilot bracket attached; secondary components like sensors or tubing may need to be reused or sourced separately depending on the kit configuration.

Can I use this as a universal burner for other brands?
No. This is a model-specific OEM part. Using it in non-certified equipment can lead to improper combustion and safety hazards.
