Reznor 197067 Gas Valve

The Reznor 197067 is an OEM 2-stage natural gas valve engineered for precision regulation in industrial and commercial unit heaters. Operating at 24V with a standard 3.5" WC (water column) manifold pressure, this valve features 3/4" NPT inlet and outlet connections to ensure high-capacity fuel delivery. As a service technician, you will find and recognize this part as the direct replacement for 195739, maintaining original factory specifications for correct burner ignition and flame stability. This natural gas valve is a critical component for high-output Reznor units, including many UDAP, UDAS, UBX, and UDX series models. Its dual-stage design allows for varying firing rates, optimizing combustion efficiency across different load demands. When performing a swap, ensure the coil voltage matches the transformer output and verify the pressure regulator setting to prevent soot buildup or delayed ignition.

Common Questions

Is the Reznor 197067 compatible with existing 195739 installations?
Yes, this is the current manufacturer-recommended replacement for the 195739 gas valve, featuring identical port sizes and wiring configurations.

Can this valve be used with liquid propane (LP)?
This specific model is configured for natural gas. For propane applications, a conversion kit or the specific LP equivalent (like the 197065) is required.

What are the symptoms of a failing stage 2 gas valve?
Typically, you will see the unit struggling to reach high-fire capacity or short-cycling while trying to satisfy the thermostat, often indicating a failed solenoid or internal diaphragm.
