Modine 3H0370460001 Conversion Kit

The Modine 3H0370460001 Conversion Kit is a specialized OEM component designed for field-converting Modine gas-fired unit heaters from liquid propane (LP) to natural gas (NG). As the direct replacement for the discontinued 3H37046-1, this kit ensures a precise fit for legacy and current inventory maintenance. Professional technicians rely on this Modine LP to natural gas conversion kit to handle standard elevation (0-2,000 ft) applications where seasonal fuel availability or utility upgrades necessitate a change in combustion requirements.

This Modine heater gas conversion package includes high-precision main burner orifices, a regulator spring kit for the gas valve, and a conversion rating plate for critical safety documentation. Utilizing genuine Modine replacement parts preserves the engineering integrity of Modine Hot Dawg and industrial unit heaters, preventing the manifold pressure issues often associated with generic alternatives. Correct installation of this natural gas conversion kit is essential for maintaining the appliance's thermal efficiency and ensuring clean, stable ignition on a natural gas supply.

• Direct Replacement: Specifically engineered to replace the 3H37046-1 without mounting modifications.
• Complete Component Set: Includes necessary gas burner orifices and valve regulator springs for a full system recalibration.
• OEM Integrity: Built to manufacturer specifications to ensure proper manifold pressure and BTU output.
• Fuel Flexibility: Enables a cost-effective transition to natural gas without replacing the entire gas-fired unit heater.

• Can this kit be used for high-altitude installations? This specific part number is designed for standard elevations up to 2,000 feet; applications above this requires specific high-altitude orifice sizing.
• Does this fit Spark Ignition or Hot Surface Ignition models? Compatibility depends on the specific control code of your unit; verify the gas valve model number and serial plate before beginning the conversion.
• Is a new gas valve included? No, the kit provides internal components to convert your existing compatible valve, not a complete replacement valve assembly.
