Modine 3H0372660004 Conversion Kit

The Modine 3H0372660004 is a precision-engineered Natural Gas to LP conversion kit designed for field-converting specific Modine unit heaters to liquid propane operation. As a genuine OEM Modine replacement part, this kit ensures the fuel system maintains its original factory performance standards while adapting to the higher BTU density of propane. The conversion process is critical for installations where natural gas utility access is unavailable, requiring exact Modine 3H0372660004 specifications to ensure the burner manifold and gas valve regulator are properly calibrated.

This Modine gas conversion kit typically includes the necessary jet orifices, a regulator spring for the gas valve, and a conversion rating plate. When performing this NG to LP conversion, technicians must verify the unit heater's control code—specifically codes 11 or 12 for spark ignition—and model prefix (such as HD, HDS, or PTP) to confirm heating system compatibility. Proper installation ensures optimized combustion and prevents soot accumulation on the heat exchanger. Always perform a leak test and confirm manifold pressure reaches the required 10" water column during commissioning to ensure reliable ignition and long-term HVAC performance.

• OEM Precision: Genuine Modine 3H0372660004 components ensure a direct fit without manifold modification.
• Performance Stability: Maintains factory-rated blower efficiency and heat output when switching to liquid propane (LP).
• Complete Calibration: Includes high-quality orifices and regulator springs to manage technical gas pressure requirements.
• Regulatory Compliance: Provided with official conversion stickers and rating plates to satisfy local mechanical codes.

Is this kit compatible with all Modine Hot Dawg heaters?
No, this kit is specifically designed for certain models, typically those with spark ignition and specific control codes. Always verify your unit's serial plate before installation.

Can I use this for high-altitude installations?
While this kit converts the fuel type, high-altitude adjustments (typically above 2,000 ft) may require additional orifice sizing or pressure adjustments as per Modine technical manuals.

Do I need specialized tools for the gas valve conversion?
Standard HVAC hand tools and a calibrated manometer are required to swap the regulator spring and verify the 10" WC manifold pressure post-conversion.
