Common Questions

Is this valve compatible with both Natural Gas and Propane?
This part is typically configured for Natural Gas (6-7" W.C. inlet). For Propane (LP) applications, a specific conversion kit and orifice adjustment are required by the manufacturer.

How do I troubleshoot a failure to ramp up?
Check the 24VAC control signal from the board. If the modulating control isn't receiving the correct voltage based on the thermostat demand, the valve may stay at low fire or fail to open.

Does this include the replacement gaskets?
This listing is for the Modine 50715730002 valve body. We recommend replacing all flange gaskets during installation to prevent hazardous gas leaks.
