Lennox 58L68 Burner Assembly

The Lennox 58L68 Burner Assembly is a high-performance 4-tube inshot burner manifold designed for precision combustion in compatible Lennox gas furnaces. This critical mechanical component, also identified by part numbers 58L6801 and LB-94731C, ensures a stable and efficient flame pattern across the heat exchanger cells. Engineered from durable steel, this setup replaces aging or warped burner clusters to restore factory-spec thermal output and prevent delayed ignition or soot accumulation. This assembly is a direct OEM replacement burner for various residential heating units, including the G23Q3/4-100-1 and 90UGFA3-100 series. For technicians performing a system overhaul, this four-tube burner assembly provides an exact fit for the mounting bracket and gas manifold orifices, ensuring the venturi effect is maintained for proper fuel-to-air ratios. Using a genuine Lennox 58L68 part maintains the integrity of the combustion box and ensures compatibility with existing flame sensors and hot surface igniters.

• Direct OEM Compatibility: Engineered as the identical replacement for Lennox 58L6801 and LB-94731C, ensuring no field modifications are required.
• Optimized Combustion: The four-tube inshot design provides a uniform flame for efficient heat transfer and reduced emissions.
• Professional Grade Construction: Built with heavy-duty materials to withstand high-temperature cycles within the burner box.
• Precision Alignment: Designed to seat perfectly in the support rings of the gas manifold, preventing fuel leaks and ensuring reliable ignition.

Is the 58L68 interchangeable with the 58L6801?
