Resideo VR8304P4256T Gas Valve

The Resideo VR8304P4256T is a high-capacity, 3/4 inch 24V slow-opening gas valve engineered for intermittent pilot ignition systems in heavy-duty residential and light commercial applications. This single-stage gas valve provides precise regulation of natural gas, supporting a flow capacity of up to 300,000 BTU/hr at a 1-inch pressure drop. The slow-opening design is critical for technicians troubleshooting rollout or ignition noise, as it ensures a controlled fuel ramp-up during the light-off cycle. Designed for HVAC gas valve replacement in high-efficiency boilers and furnaces, the dual-valve seat architecture provides redundant safety shutoff. The unit features 1/4-inch male quick-connect terminals for seamless electrical integration and includes both inlet and outlet pressure taps to simplify manifold pressure adjustments during commissioning. Use this Resideo (formerly Honeywell) component to restore system reliability where stable combustion and robust gas flow control are required.

• Enhanced Ignition Stability: The slow-opening actuator mitigates hard starts and minimizes burner resonance.
• High BTU Capacity: 3/4" x 3/4" NPT sizing supports larger BTU loads common in light commercial boilers.
• Intermittent Pilot Compatibility: Optimized for use with S8610 and other electronic ignition modules.
• Field Serviceability: Includes pressure taps for accurate clocking of the meter and manifold setting.
• Safety Redundancy: Dual solenoid seats provide two levels of gas shutoff for code compliance.

Can the VR8304P4256T be used with Liquid Propane (LP)?
This model is factory-configured for natural gas. For LP applications, a specific 393691 conversion kit must be installed to ensure correct spring tension and regulator response.

What is the purpose of the slow-opening feature?
It provides a timed delay during the initial gas flow, allowing the pilot to establish a stable flame before the main burner reaches full manifold pressure, reducing mechanical stress on the heat exchanger.

What is the electrical rating for the solenoid coils?
The valve operates on a standard 24 VAC, 60 Hz transformer, drawing approximately 0.7 Amps during the main valve hold-in phase.
