Lennox 14N29 Conversion Kit
When your field installation requires a transition from natural gas to liquid propane, the Lennox 14N29 Conversion Kit (LB-107321P) provides the specific OEM components needed for a code-compliant fuel changeover. This NAT TO LP CONVERSION KIT is engineered for high-capacity Lennox packaged gas units, specifically those ranging from 156-360 models featuring 9-burner configurations. This LP conversion kit includes precision-machined 0.052 burner orifices and matching valve regulator springs to ensure the manifold pressure is correctly calibrated for the higher energy density of propane. As a genuine Lennox HVAC replacement part, it maintains the structural integrity and combustion efficiency of the original heat exchanger assembly. Technicians can rely on the included gas conversion stickers and technical instructions to complete the 14N29 installation while adhering to local mechanical codes. Using this OEM propane conversion kit prevents the common soot accumulation and over-firing issues associated with mismatched aftermarket components in commercial and residential heating platforms.
Key Benefits- Precision Orifice Machining: Includes 0.052-sized orifices designed for optimal gas velocity and flame stability in 9-burner systems.
- OEM Compatibility: Specifically engineered for Lennox 156-360 series packaged units to ensure seamless mechanical and thermal alignment.
- Complete Calibration Set: Provides all necessary regulator springs and conversion labels required for a professional field transition.
- Enhanced System Reliability: Prevents heat exchanger stress by maintaining proper BTU input ratings after fuel source modification.
Which Lennox models are compatible with the 14N29 kit?
This kit is designed for 13 to 25-ton Lennox packaged gas units and residential systems with 9 burners, specifically identified under part numbers 14N29 and LB-107321P.
What is the primary difference between this and a standard conversion kit?
The 14N29 is calibrated for high-volume commercial HVAC equipment, providing specific orifice counts and diameter sizes that smaller residential kits do not include.
Does this kit include the gas valve regulator springs?
Yes, the kit includes the necessary springs to adjust the gas valve for the specific manifold pressure required by liquid propane.
