Resideo VR8305P4279 Valve
The Resideo VR8305P4279 is a heavy-duty 3/4 inch direct ignition gas valve engineered for high-output single stage gas furnaces and commercial heating equipment. Built with a straight-through body pattern, this dual automatic combination valve handles capacities ranging from 30,000 to 415,000 BTU, making it a versatile choice for direct spark (DSI) and hot surface ignition (HSI) systems. This specific model features a step-opening regulator, factory-set at 0.9" WC step and 3.5" WC full rate, ensuring controlled ignition and stable manifold pressure during high-demand cycles. The 24VAC coil is designed for seamless integration with standard HVAC control boards, while the 1/8" NPT pressure tapping with plug allows for precise field clocking and troubleshooting. Built to withstand a 1/2 PSI inlet pressure rating, this 24V gas manifold valve provides the reliability required for rigorous residential and light commercial applications.
Key Benefits- Wide BTU Capacity: Supports 30,000 to 415,000 BTU, covering a broad range of HVAC replacement parts requirements.
- Step-Opening Logic: Reduces burner noise and ensures smooth light-off by initiating flow at 0.9" WC before reaching full rate.
- Universal Ignition Compatibility: Optimized for use with direct spark ignition and hot surface modules.
- Internal Filtration: Equipped with an internal screen to protect the valve seat from line debris and contaminants.
- Compact Footprint: The straight-through design simplifies piping in tight furnace cabinets and rooftop units.
Is the VR8305P4279 compatible with LP gas conversion?
Yes, while factory-configured for natural gas, this valve can be converted for Liquid Propane using the appropriate Resideo 393691 conversion kit.
Can I use this for a standing pilot system?
No, this is a direct ignition dual valve. It does not have a pilot gas outlet and is strictly for HSI or DSI systems where the main burner is ignited directly.
What are the wiring requirements?
This unit utilizes 1/4 inch male quick-connect terminals and requires a constant 24VAC signal from the ignition controller to maintain the solenoid circuit.
