Reznor 121600 Gas Valve

The Reznor 121600 Gas Valve is a professional-grade liquid propane (LP) gas control engineered for high-performance spark ignition systems. This specific 24V gas valve features a standard 1/2" NPT inlet and a 3/4" NPT outlet, making it a drop-in replacement for a wide range of Reznor unit heaters and duct furnaces. Designed to handle the rigorous demands of commercial and industrial heating environments, the Reznor 121600 ensures precise fuel regulation and reliable burner sequencing. Often cross-referenced as the VR8304H3802, this valve is critical for maintaining safe combustion and optimal thermal efficiency in LP-fired equipment. As an OEM Reznor replacement part, it eliminates the compatibility guesswork often associated with universal components, providing a secure fit and stable manifold pressure for consistent heating cycles even in extreme cold-start conditions.

• Engineered for Propane: Factory-calibrated for LP gas applications to provide stable 10" W.C. manifold pressure.
• Versatile Connection Sizes: Features a 1/2" x 3/4" NPT configuration to accommodate standard unit heater gas trains.
• Spark Ignition Compatible: Seamlessly integrates with 24VAC spark-to-intermittent pilot control boards for rapid system response.
• Robust Solenoid Design: Heavy-duty internal coils withstand frequent cycling common in high-demand warehouse and industrial settings.
• Compact Footprint: Designed for easy installation in tight furnace cabinets where space for pipe wrenches and tools is limited.

What equipment is the Reznor 121600 compatible with?
This valve is primarily used in Reznor LP-fired unit heaters and duct furnaces requiring a 24V signal and a 1/2" x 3/4" gas connection. Always verify your specific model's serial number and gas type before installation.

Can this valve be used for natural gas?
No, the 121600 is specifically regulated for Liquid Propane (LP). Installing this on a natural gas system without a proper conversion kit and recalibration can lead to dangerous over-firing and equipment failure.

How do I troubleshoot a 24V gas valve that won't open?
Verify you have 24VAC across the terminals during the ignition trial. If voltage is present but the valve doesn't click or allow gas flow to the spark ignition pilot, the internal solenoid likely has an open circuit and requires replacement of the entire assembly.
