Common Questions

Is this valve compatible with natural gas systems?
No, the Modine 5H0798690000 is strictly engineered for propane (LP) gas. For natural gas applications, a different OEM part number must be used to ensure correct orifice sizing and pressure regulation.

What Modine models does this gas valve fit?
This OEM gas valve is widely used in Modine HD30, HD45, HD125, and equivalent HDS, HDB, and PTC series unit heaters manufactured after May 2007 with direct spark ignition.

Can this part replace a standing pilot valve?
This model is typically utilized with intermittent spark or direct spark ignition systems. If you are servicing an older standing pilot unit, verify the voltage and connection requirements, as some legacy systems require an upgrade to modern electronic ignition modules.
