Resideo VR8300H4501 Valve

The Resideo VR8300H4501 is a commercial-grade, single-stage standing pilot gas valve designed for high-capacity 24VAC appliances ranging from 30,000 to 290,000 BTU/hr. Engineered for reliability in standard heating applications, this combination gas control features a slow opening characteristic to ensure smooth ignition and reduced system stress. The 3/4" x 3/4" NPT straight-through body pattern with an integral flange provides a robust connection for high-flow installations. As a direct crossover for the CNT2698, it integrates a factory-set 3.5" WC servo regulator to maintain consistent output pressure despite fluctuations in supply. This dual automatic valve incorporates a solenoid-operated first operator and a diaphragm-assisted second operator for redundant safety shutoff. All pilot adjustments, 1/4" quick-connect terminals, and the 1/8" NPT pressure tap are accessible from the top, facilitating rapid field diagnostics and setup for service technicians. This 24V gas valve is a versatile solution for multi-family and commercial boiler or furnace retrofits.

• Direct Cross-Reference: Identical performance and footprint to the CNT2698, ensuring seamless drop-in replacement.
• Dual Safety Operators: Redundant automatic valves provide secondary shutoff protection during pilot or power failure.
• Slow Opening Design: Minimizes "booming" during ignition for quieter, more reliable burner starts.
• High Capacity Range: Optimized for systems between 30,000 and 290,000 BTU with a 1/2 PSI pressure rating.
• Service Accessibility: Top-mounted terminals and pressure taps reduce installation time and simplify testing.

• Can this valve be converted for Liquid Propane (LP) use? Yes, this Resideo gas valve can be converted using a standard 393691 Natural to LP conversion kit designed for the VR8300 series.
• Will this replace a fast-opening valve? While it can replace some fast-opening models if the capacity matches, the slow opening gas valve feature is specifically required for appliances where controlled ignition is necessary to prevent burner rollout.
• Is this compatible with electronic ignition systems? No, the VR8300H4501 is strictly for standing pilot applications and requires a continuous pilot light to operate. It is not a direct replacement for HSI or DSI valves.
