Modine 3H0372760001 Conversion Kit

The Modine 3H0372760001 is a specialized LP to NAT Gas conversion kit designed for high-efficiency thermal management in select Modine heating units. As the direct engineering replacement for legacy part number 3H37276-1 (also referenced as 53214), this kit is essential for contractors transitioning equipment from liquid propane to natural gas. The kit is specifically configured for compatibility with unit heater series including Modine HD75, HDS45, and HD60 models. Each component is manufactured to maintain the precise manifold pressure and BTU output required for safe, reliable operation post-conversion.

This comprehensive gas furnace conversion kit includes five #49 burner orifices, a Honeywell 396222 valve conversion for VR8205S single-stage valves, and a White Rodgers 92-0656 conversion suitable for 36C, D, E, G, H, and J series valves. By utilizing OEM Modine replacement parts, technicians ensure that the heating system adheres to original factory specifications and local gas regulations. Proper installation of the included orifices and regulator springs ensures optimal combustion and prevents soot accumulation or delayed ignition often seen with improper field conversions. Always verify your specific model and serial number against the installer's guide to ensure this natural gas conversion matches your heater’s cabinet size and valve configuration.

Key Benefits:

• Direct OEM Match: Ensures precise fitment and eliminates the risk of bypass leaks common with universal kits.
• Broad Valve Compatibility: Includes hardware for both Honeywell and White Rodgers single-stage gas valves.
• Validated Performance: Maintains the Modine unit heater thermal efficiency ratings after switching fuel sources.
• Complete Hardware Set: Contains all necessary orifices and conversion decals required for a code-compliant installation.

Common Questions:

Can I use this kit for a two-stage Modine heater?
No, this specific kit is engineered for single-stage gas valves. Two-stage units require different regulator springs and manifold pressure settings.

Is the 3H0372760001 compatible with older Modine PowerVented units?
This kit is primarily designed for the HD/HDS series. For legacy PA or PV models, cross-reference your specific manifold size, as orifice requirements may differ.

Why does the kit include multiple valve conversion springs?
Modine utilizes different valve manufacturers across their production lines; providing both Honeywell and White Rodgers components ensures the technician has the correct regulator spring regardless of the valve brand installed in the unit.
