Nordyne 904404A Conversion Kit

The Nordyne 904404A LP Conversion Kit is a critical field-service component designed for intertherm furnace gas conversion from natural gas to liquid propane. Engineered for precision and safety, this LP gas conversion kit ensures the manifold pressure and burner orifices are correctly sized for Miller mobile home furnaces and Nordyne G5, G6, and M1G series units. Using high-grade OEM furnace replacement parts like this kit prevents improper combustion and hazardous soot buildup. For a reliable furnace LP conversion, technicians must verify the Honeywell or White Rodgers gas valve model currently installed to ensure the included regulator springs and brass orifices match the required BTU output. Proper installation requires a calibrated manometer to set the 10" W.C. outlet pressure necessary for efficient combustion in high-altitude or standard-density propane applications. This kit streamlines the HVAC fuel conversion process, maintaining factory-specified performance standards for residential and light commercial equipment.

• Precision Orifices: Properly sized brass fittings ensure correct burner impingement and eliminate delayed ignition.
• Regulator Alignment: Includes conversion springs to recalibrate the gas valve regulator for liquid propaneÆs higher energy density.
• OEM Compatibility: Specifically designed for Nordyne 904404A applications, ensuring fitment with original heat exchangers.
• System Efficiency: Restores peak thermal efficiency and prevents excessive carbon monoxide production common with improvised conversions.

Is this kit compatible with all Nordyne gas valves?
This kit is engineered for specific Honeywell and Robertshaw valves used in M, G, and C series furnaces. Check your valve model against the technical documentation to ensure the spring fits correctly.

What manifold pressure is required after installation?
For most liquid propane applications in these units, the manifold pressure should be dialed to 10" W.C. using the provided regulator components.

Can I use these orifices for a natural gas conversion?
No, this kit is exclusively for LP gas conversion. Natural gas requires larger orifice diameters and different regulator tensioning.
