Lennox 25W20 Conversion Kit
The Lennox 25W20 Conversion Kit (LB-94723D) is a factory-authorized solution designed to transition Lennox G40 and G50UH/DF series gas furnaces from natural gas to liquid propane (LP). This OEM LP conversion kit is engineered to maintain precise manifold pressure and combustion efficiency, ensuring the gas valve operates safely within manufacturer specifications. The kit includes burner orifices, high-performance regulator springs, and the necessary technical conversion labels required for a code-compliant installation by a licensed HVAC technician. Using genuine Lennox replacement parts ensures seamless compatibility with White-Rodgers 36G series or Honeywell gas valves typically found in these residential units. For contractors working in off-grid or rural areas, this natural to propane changeover kit is essential for adjusting fuel flow rates to match the higher energy density of LP gas, preventing soot accumulation and ensuring reliable ignition cycles in demanding environments. This HVAC fuel conversion is critical for maintaining equipment integrity and operational safety.
Key Benefits- System Compatibility: Precision-engineered for Lennox G40, G50UH, and G50DF series furnace models.
- Complete Setup: Includes all required LP orifices and regulator springs for a full NAT to LP conversion.
- Optimized Combustion: Designed to provide the correct orifice sizing to maintain BTU output after fuel switching.
- Regulatory Compliance: Includes factory-required conversion stickers to satisfy local inspections and safety codes.
- Which Lennox furnaces are compatible with the 25W20 kit? This kit is specifically designed for the G40 and G50 series. Always verify the part number LB-94723D against your unit's nameplate.
- Does this kit work with any gas valve? It is configured for the White-Rodgers and Honeywell valves used in the specified Lennox series.
- Is a professional required for installation? Yes, fuel conversions must be performed by a qualified HVAC contractor to ensure proper gas pressure adjustment and leak testing.
