Lennox 27M18 Orifice
The Lennox 27M18 Orifice is a precision-engineered 052-sized flow control component essential for maintaining the manifold pressure and combustion efficiency of Lennox commercial and residential heating systems. Designed as a direct OEM replacement part, this orifice (MPN: 27M18, replaces LB-99225) ensures accurate gas metering for Lennox T-Class rooftop units and gas furnaces, specifically compatible with models including KGA036S4, KGA092, and LGH180 series. For technicians, installing a genuine Lennox 052 orifice is critical for achieving the specified BTU output and preventing soot accumulation or burner damage caused by improper air-fuel ratios. Manufactured from high-grade brass to resist corrosion and thermal fatigue, this fixed-metering device regulates flow with strict tolerances, preserving the structural integrity of the burner assembly. Whether transitioning between gas types or performing a routine HVAC orifice replacement, using the correct Lennox gas orifice ensures the system operates within OEM peak performance parameters without sacrificing safety or reliability in demanding high-demand environments.
Key Benefits- Precision Flow Calibration: Features a calibrated 052 bore size for exact fuel-to-air mixing in Lennox gas furnace applications.
- Direct OEM Compatibility: Engineered for an exact fit in Lennox rooftop units and heat pumps, eliminating the need for field modifications.
- High-Durability Construction: Built from robust materials to withstand the high-temperature environment of the burner flame assembly.
- Regulatory Compliance: Maintains the original factory certifications and system efficiency ratings (ASHRAE/DOE) of the host equipment.
- Optimized Performance: Prevents common issues like short-cycling or inefficient combustion by providing consistent manifold pressure regulation.
What models are compatible with the Lennox 27M18?
This 052 orifice is widely used in Lennox T-Class units and various KGA/LGH commercial models. Always verify the specific burner manifold part number before installation.
Can I use a universal orifice instead of the 27M18?
While universal options exist, they often lack the exact technical specifications and threading required for Lennox proprietary gas valve assemblies, which can lead to leaks or improper pressure.
When should an HVAC orifice be replaced?
Replacement is recommended during gas type conversions (Natural Gas to Propane) or if the orifice becomes obstructed by debris, causing inconsistent burner flame patterns.
