Resideo VR8304M4002/B Gas Valve

The Resideo VR8304M4002/B is a high-capacity 24V gas valve engineered for intermittent pilot ignition systems in residential and light commercial natural gas furnaces and boilers. As a critical furnace gas control valve, it features a 3/4-inch NPT inlet and outlet, supporting high-BTU load demands while maintaining precise manifold pressure. This Honeywell gas valve replacement is rated for a standard 3.5-inch W.C. outlet pressure, ensuring optimal burner performance and flame stability. The internal components are designed to withstand the rigorous cycling of modern HVAC systems, providing reliable sequencing for both the pilot and main burner. For technicians performing a 3/4 inch natural gas valve swap, this unit serves as a robust HVAC gas regulator valve with a straightforward 90-degree or straight-through mounting capability. It integrates a manual ON-OFF switch and high-quality electromagnetic solenoids to ensure positive shutoff and safe operation across various heating platforms.

• Universal Compatibility: Works as a direct replacement for many legacy Honeywell VR8304 series valves in 24V intermittent pilot systems.
• High-Flow Design: Features 3/4" x 3/4" NPT connections to accommodate higher capacity furnace and boiler applications.
• Reliable Regulation: Factory-set at 3.5" W.C. for natural gas, providing consistent pressure to the orifice manifold.
• Field Practicality: Includes a manual shutoff valve and terminal designations labeled for clear wiring during installation.
• Operational Temperature Range: Rated for ambient temperatures from -40°F to 175°F, ensuring performance in unconditioned mechanical rooms.

How do I replace a 24V furnace gas valve like the VR8304M4002/B?
Ensure the gas supply and power are disconnected. Match the pipe sizing and verify the 24V control signal. Always perform a soap bubble leak test and check manifold pressure after installation.

Is the VR8304 compatible with natural gas systems?
Yes, this model is specifically calibrated for natural gas. For LP applications, a conversion kit must be utilized to adjust the regulator spring tension.

What is the Resideo VR8304M4002/B used for in modern heating?
It serves as the primary control for gas flow in systems requiring intermittent pilot ignition, managing the safety timing and flow for both the pilot flame and main burner assembly.
