Lochinvar & A.O. Smith 100110794 Tube

The Lochinvar & A.O. Smith 100110794 Vertex Burner Tube is a high-precision OEM replacement component engineered for top-mounted, down-fired radial burner systems. Specifically designed for the A.O. Smith Vertex and Cyclone HE BTX-80 series, this stainless steel burner tube facilitates a stable premix combustion process to maintain high thermal efficiency in condensing gas water heaters. By ensuring uniform flame distribution across the cylindrical surface, this Vertex burner kit optimizes heat transfer within the helical coil heat exchanger, reducing emissions and preventing the "lazy flame" conditions that lead to carbon sooting and diagnostic lockouts. For field technicians, this assembly serves as the direct 9005988205 replacement, providing a drop-in fit for rapid restoration of high-recovery performance in residential and light commercial hydronic applications. The burner tube assembly is compatible with both natural gas and propane configurations, ensuring reliable ignition and consistent BTU output across a wide range of operating pressures.

• OEM Compatibility: Exact Lochinvar 100110794 factory part ensures correct orifice alignment and pressure drop specs.
• Enhanced Combustion: Radial fire design promotes a clean, concentrated flame pattern to maximize fuel-to-air ratios.
• Durability: Constructed from corrosion-resistant cylindrical stainless steel to withstand high-temperature cycling in condensing environments.
• Optimized Efficiency: Critical for maintaining the 94% thermal efficiency rating of Vertex water heaters.

Common Questions

When should the burner tube be replaced in a Vertex unit?
Replacement is typically necessary if you observe significant oxidation, clogged ports that cannot be cleared, or persistent "Ignition Failure" codes on the UIM display caused by poor flame sensing grounding on the burner surface.

Does this kit include the mounting flange gasket?
This part number refers to the Vertex Burner Tube itself. It is recommended to inspect the blower flange gasket during removal and replace it if the seal shows signs of compression set or tearing to prevent combustion gas bypass.

Is this tube compatible with the Cyclone commercial series?
Yes, the 100110794 is the specified burner tube assembly for the Cyclone HE BTX-80 models. Always verify your specific model and serial number against the manufacturer’s parts list to confirm exact port geometry.
