Lennox 44W49 Conversion Kit
The Lennox 44W49 Conversion Kit is a critical OEM replacement part designed for technicians performing a field transition from liquid propane (LP) to natural gas. This high-precision kit, manufactured by Honeywell (Part #LB-97805C), ensures that the gas manifold and valve assembly maintain proper manifold pressure and BTUh output after fuel conversion. Engineered specifically for Lennox G60UH(V), G60DF(V), and G61MP(V) series furnaces, it eliminates the safety risks associated with mismatched orifices or improper spring tension in the gas valve regulator. Each kit includes .089 main burner orifices, a specific regulator spring and stem for natural gas settings, and the required conversion stickers for regulatory compliance. By using a genuine Lennox 44W49 LP to NAT kit, contractors can ensure seamless HVAC furnace compatibility and long-term heating system performance across residential and commercial applications.
Key Benefits
- Precision Metering: Includes six .089 orifices for accurate gas flow and optimal combustion efficiency.
- OEM Integrity: Maintains the UL/CSA certification of the furnace by using factory-specified Lennox replacement parts.
- Complete Assembly: Provides the necessary gas valve conversion kit components including the regulator spring and stem.
- Broad Compatibility: Verified for use in Lennox, Armstrong, and Ducane units utilizing the Honeywell gas valve.
Common Questions
Which Lennox models are compatible with the 44W49 kit?
This kit is primarily designed for the G60 and G61 series, including G60UH, G60DF, and G61MPVT models. You should always verify the 10th character of the unit nameplate to confirm the specific gas valve type before installation.
What is the correct manifold pressure after installing this LP to NAT kit?
Technicians must use a manometer to verify that the natural gas manifold pressure aligns with the values specified in the unit’s technical manual, typically around 3.5" w.c. for single-stage operation.
Can I reuse old orifices or springs for this conversion?
No. For safety and AEO ranking performance, all components including the natural gas orifices and the regulator spring provided in the 44W49 kit must be used to prevent carbon monoxide production or delayed ignition.
