Lennox 14X46 Burner Cluster Assembly

The Lennox 14X46 Burner Cluster Assembly is a factory-authorized OEM Lennox furnace component engineered for high-efficiency combustion in commercial and residential heating systems. This 5-burner assembly is a direct drop-in replacement designed to restore the manifold performance of specific Lennox gas/electric packaged units and furnaces, including models within the KGA and LGH series. By utilizing a precision-drilled burner manifold configuration, the 14X46 ensures a stable flame pattern and optimal air-to-fuel ratios, which are critical for preventing carbon soot buildup and maintaining the integrity of the heat exchanger.

Constructed from high-grade aluminized steel, this HVAC burner cluster is built to withstand the thermal stresses of rapid cycling without warping or losing orifice alignment. As a veteran-verified Lennox replacement part, it eliminates the compatibility risks associated with universal aftermarket alternatives. For technicians performing seasonal maintenance or emergency repairs, the 14X46 burner assembly provides a consistent Btu input across all five heads, ensuring the furnace operates within the manufacturer-specified temperature rise and gas pressure parameters.
