Resideo VR8300C4035 Valve

The Resideo VR8300C4035 Valve is a robust, 24VAC standing pilot gas valve engineered for consistent performance in residential and light commercial heating systems. Designed as a dual automatic combination valve, it integrates a manual valve, two automatic operators, and a servo pressure regulator into a single compact housing. This specific model features 3/4" x 3/4" NPT straight-through connections with an integral flange, supporting a wide heating capacity from 30,000 to 290,000 BTU/hr. The step opening characteristic, factory-set with a 2.5" WC step and 10" WC full rate, ensures smooth ignition and stable burner pressure even during supply fluctuations. Built for reliability in the field, all wiring terminals and pressure taps are top-accessible, simplifying gas valve replacement and diagnostic testing. It is fully compatible with S86 and S8600 control modules, meeting strict codes for dual safety shutoff in LP gas furnace and boiler applications.

• Dual safety shutoff compliance with solenoid and diaphragm-operated valves for redundant protection.
• Step opening regulation prevents hard ignitions by providing a controlled 2.5" WC initial gas flow before reaching full 10" WC pressure.
• Flexible mounting allows for installation from 0 to 90 degrees in any direction from the upright position.
• Service-friendly design includes 1/4" quick-connect terminals and a 1/8" NPT pressure tap with plug for fast manifold pressure adjustments.
• High-capacity flow rated up to 290,000 BTU/hr to support large-scale residential and light commercial equipment.

Is the Resideo VR8300C4035 compatible with natural gas?
While this unit is factory-configured for LP gas at 10" WC, conversion kits are typically required for natural gas applications. Always verify the regulator spring and orifice requirements per the equipment manufacturer’s specifications.

What are the electrical requirements for this combination valve?
This is a 24VAC low voltage gas valve, drawing approximately 0.7A. It is designed to interface directly with 24V thermostats and pilot restart ignition modules like the Honeywell S8600 series.

Can this valve be used in a horizontal orientation?
Yes, the Resideo VR8300C4035 is rated for mounting in any position from upright to 90 degrees, including vertical, providing versatility in tight mechanical closets and furnace cabinets.
