Common Questions

Will this valve work for both Natural Gas and Propane (LP)?
The Modine 5H0731000003 is configured for natural gas applications. For propane conversions, a specific LP conversion kit must be utilized to ensure correct orifice sizing and pressure regulation.

Is this a direct replacement for 5H73100-3?
Yes, the 5H0731000003 is the official supersede for part number 5H73100-3. It maintains the same footprint, electrical requirements, and BTU throughput ratings as the original component.

Can I install this valve on a 120V system?
No, this is a 24V gas valve. Connecting this unit to a 120V line will cause immediate electrical failure of the solenoid coil and presents a significant safety risk.
