Reznor 176680 Gas Valve

The Reznor 176680 is a standard-opening natural gas valve designed for precision fuel regulation in heavy-duty unit heaters and industrial furnaces. This 24V gas valve operates with a fixed setting of 3.5" WC (Water Column) to ensure optimal manifold pressure and consistent burner performance. As a direct OEM replacement part, it is the primary successor to the obsolete Honeywell VR8204M1901, maintaining the exact 1/2" x 1/2" NPT connection specs required for a drop-in installation without manifold modification. Engineered for high-demand environments, this low voltage gas control supports a flow capacity often utilized in equipment reaching up to 500,000 BTU/hr. For technicians servicing Nortek or Reznor systems, utilizing this genuine Reznor 176680 valve ensures the appliance remains within original manufacturer specifications for safety and combustion efficiency. The compact solenoid-operated design provides reliable pilot and main burner control across various gas-fired boilers and unit heaters.

• Universal Compatibility: Serves as the official replacement for Honeywell VR8204M1901, preventing the need for field-fitting or specialized adapters.
• Direct OEM Specification: Pre-set to 3.5" WC for natural gas, eliminating the risk of over-firing or poor combustion cycles.
• Reliable 24V Logic: Interfaces seamlessly with standard HVAC ignition modules and 24VAC control circuits for immediate response times.
• Robust Build Quality: Constructed with high-grade internal components to withstand the steady-state thermal stress of industrial HVAC unit heaters.

Is the Reznor 176680 compatible with Propane (LP) systems?
No, this specific model is calibrated for natural gas (NG) at 3.5" WC. Use in LP applications requires a specific conversion kit or a dedicated LP valve calibrated to 10" WC to ensure safe operation.

Can I use this valve to replace a Honeywell VR8204M1901?
Yes, the Reznor 176680 is the direct current replacement for the Honeywell VR8204M1901 gas valve found in many older Reznor heating units.

What are the inlet and outlet sizes for this gas control?
This valve features standard 1/2 inch NPT threaded connections for both the inlet and the outlet, common in most commercial gas lines.
