Lennox 27K66 Burner

The Lennox 27K66 Inshot Burner is an OEM replacement part engineered for high-efficiency atmospheric combustion in residential and commercial furnaces. As a veteran-grade furnace burner replacement, this component is designed specifically to withstand the thermal stress of high-cycle heating demands. It effectively replaces legacy part numbers 27K6601, 65257000, and LX013, ensuring your system maintains its original factory specifications for flame stability and fuel conversion efficiency. This steel inshot burner features a precision-engineered orifice alignment that eliminates the need for manual air adjustments, providing a consistent, concentrated flame pattern for optimal heat exchanger transfer. Whether you are performing a seasonal overhaul on a Lennox TUA series unit or addressing igniter alignment issues in a natural gas furnace, this genuine Lennox HVAC part ensures the combustion process remains clean and quiet, reducing the risk of flame rollout or soot accumulation within the heat cell.

Key Benefits
  • Direct OEM Compatibility: Engineered as a drop-in replacement for Lennox, Armstrong, and Ducane units, ensuring precise fitment and gas manifold alignment.
  • Durable Steel Construction: High-grade stainless steel or aluminized steel build resists oxidation and corrosion from combustion byproducts.
  • Optimized Combustion: The inshot burner design facilitates a venturi effect for the ideal air-to-fuel ratio without complex field calibrations.
  • Flame Stability: Superior carryover port design ensures immediate ignition across the entire burner rack, reducing "delayed ignition" noise and wear.
Common Questions

Is the Lennox 27K66 compatible with propane (LP) systems?
The burner itself is compatible with both fuels; however, the orifice size and gas valve regulator settings must be converted specifically for LP applications by a licensed technician. Always check your manifold pressure.

When should I replace my inshot burners instead of cleaning them?
If you observe significant pitting, rust at the carryover ports, or "cherry-red" hotspots during operation, the structural integrity is compromised. Replace the burner to prevent inefficient combustion or heat exchanger damage.

Does this burner require a specific flame sensor?
While the burner supports the combustion process, ensure your existing flame sensor is clean and positioned correctly within the flame path of the last burner in the rack for proper rectification.
