Lennox 77W89 Conv Kit
As a seasoned technician, you know that field-converting a Lennox gas furnace requires precise 1:1 OEM components to maintain manifold pressure specs. The Lennox 77W89 Natural to LP Conversion Kit (also identified as Lennox 103191-01) is the industry-standard solution for adapting your White Rodgers 36H series gas valve from natural gas to liquid propane. This LP gas conversion kit is engineered to handle the higher energy density of propane, ensuring your gas valve assembly operates within the strict 10" W.C. to 11" W.C. manifold pressure range required for safe combustion.
This kit is a staple for HVAC contractors working on Lennox Elite and Merit series units, including popular models like the 95AF2DF and EL280UH. It includes high-viscosity replacement springs color-coded for quick identification and the necessary orifices to prevent "sooting" or delayed ignition. By utilizing this genuine Lennox OEM part, you eliminate the guesswork of third-party alternatives, ensuring the thermocouple and flame sensor readings remain stable under the new fuel profile. Whether you are performing a new installation or a site retrofit, the 77W89 provides the mechanical reliability needed for high-efficiency furnace fuel conversion.
Key Benefits for the Contractor- Precision Calibration: Includes OEM-spec regulator springs designed specifically for the White Rodgers 36H valve housing.
- System Compatibility: Validated for a wide range of Lennox residential furnaces and light commercial unit heaters.
- Safety Compliance: Facilitates proper manifold pressure adjustment to meet local HVAC codes and manufacturer requirements.
- Complete Hardware: Comes with the necessary main burner orifices and conversion decals for professional documentation.
Can I use the original natural gas orifices with the 77W89 springs?
No. Propane has a higher BTU content per cubic foot. You must swap the natural gas orifices for the LP orifices included in the kit to prevent over-firing and heat exchanger damage.
Which gas valves is this kit compatible with?
The 77W89 is specifically designed for White Rodgers 36H series valves found in many Lennox furnaces. Always verify the valve model number on the rating plate before installation.
What is the typical manifold pressure for this LP conversion?
After installing the 77W89 conversion kit, you should typically adjust the outlet manifold pressure to approximately 10.0" W.C., though you should always refer to the specific unit’s nameplate for final settings.
