Lochinvar & A.O. Smith 100112344 Burner Assy
The Lochinvar & A.O. Smith 100112344 Burner Assy is a critical OEM replacement component designed for high-efficiency natural gas water heaters and commercial boilers. This 16-inch burner assembly features a precision-drilled #39 orifice, engineered to maintain the exacting gas-to-air ratios required for clean combustion and optimal thermal output. As a genuine Lochinvar replacement part, it ensures seamless integration with compatible hydronic systems, preventing the common flame lifting or resonance issues often associated with generic alternatives. For field technicians, this assembly simplifies the combustion calibration process, effectively reducing gas consumption while stabilizing the water heater heat output. Built to withstand high-temperature cycling, the 100112344 natural gas burner is a standard professional choice for restoring energy efficiency in residential and commercial heating setups. Its lightweight 2.95 lb construction allows for straightforward handling during overhead or confined-space installations.
Key Benefits- Precision Gas Regulation: The integrated #39 burner orifice ensures consistent BTU delivery and prevents incomplete combustion.
- OEM Compatibility: Specifically engineered for Lochinvar and A.O. Smith units, ensuring the venturi and flame patterns meet factory specifications.
- Enhanced Efficiency: Restores peak performance to 16-inch burner trays, decreasing emissions and lowering monthly operational costs.
- Rugged Durability: Constructed from heavy-duty materials to resist oxidation and warping in high-BTU environments.
- Is this assembly compatible with Propane (LP) units? No, this specific part number is calibrated for Natural Gas burner applications only. Using it with LP requires a different orifice size to avoid hazardous over-firing.
- Doe it include the pilot assembly or igniter? This part number typically covers the main burner assembly; check your specific model’s manifold drawing to confirm if additional pilot lines are required.
- Why is my unit locking out after installation? Ensure the 16-inch manifold is seated correctly and that the natural gas #39 orifice is free of debris. Always verify manifold pressure against the unit’s data plate after replacement.
