Nordyne 904090A Conversion Kit

The Nordyne 904090A Conversion Kit is a field-proven solution for transitioning residential and light commercial gas furnaces from natural gas to liquid propane. As an OEM replacement part, this kit ensures precise orifice sizing and pressure regulation adjustments necessary to maintain the combustion integrity of Nordyne systems. For the service contractor, using this NAT to LP conversion kit is essential for meeting manufacturer specifications and avoiding the common manifold pressure issues associated with generic components.

Engineered for high-performance HVAC gas furnace models, the package includes the primary burner orifices and a gas valve conversion spring kit to recalibrate the regulator. By accurately matching the LP gas conversion requirements of the heat exchanger, technicians can verify BTUH input ratings and ensure flame stability across all burner tubes. This kit simplifies the conversion process on the job site, reducing labor time while maximizing equipment reliability and efficiency in propane-fired applications.

Key Benefits:

• Ensures exact manifold pressure for efficient LP gas conversion.
• Maintains equipment safety standards with OEM replacement part precision.
• Prevents soot accumulation and heat exchanger fatigue caused by improper fuel mixtures.
• Facilitates seamless integration with existing gas valve manifolds.
• Reduces troubleshooting time by providing all necessary furnace repair parts for the conversion.

Common Questions:

Will this kit fit any Nordyne furnace?
This 904090A kit is model-specific; technicians should verify cross-reference data against the nameplate to ensure compatibility with the specific BTU rating and valve series.

Why can't I just change the orifices?
Conversion requires a gas valve conversion spring to adjust the internal regulator for the higher pressure typical of propane, ensuring the burner operates within safe parameters.

Is field conversion approved for all climates?
Yes, when performed by a licensed technician using Nordyne 904090A components, the system will provide stable heating performance regardless of outdoor ambient conditions.
