Resideo VR8345M4302 Gas Valve

When you're out in the field and need a reliable swap for 24V furnace controls, the Resideo VR8345M4302 Gas Valve is your go-to universal solution. Designed for high-capacity applications up to 300,000 BTU/hr for natural gas (at 1" pressure drop), this single-stage valve handles intermittent pilot ignition, direct spark ignition, and hot surface ignition systems with ease. The 3/4" x 3/4" NPT straight-through body and 4-inch swing radius make it easy to drop into tight vestibules where other valves won't fit. This Honeywell Home universal gas valve features a standard 3.5" water column setting, clearly marked keyed terminal blocks for 1/4" quick-connects, and an internal inlet screen to keep debris from fouling the seat. Whether you're dealing with residential or light commercial equipment, this dual direct ignition and intermittent pilot gas control ensures your truck is always stocked for the next service call. It is functionally identical to the VR8345M4302/U and includes a natural gas to LP conversion kit plus reducer bushings for maximum field flexibility.

• Universal Field Replacement: Consolidates inventory by replacing hundreds of IP, HSI, and DSI gas controls from Honeywell and competitors.
• Compact Installation: Features a 4-inch swing radius and multipoise mounting (0 to 90 degrees), perfect for cramped high-efficiency furnace cabinets.
• Full Accessory Kit: Ships with (2) 3/4" x 1/2" reducer bushings and a comprehensive LP conversion kit for immediate onsite adaptation.
• Top-Accessible Adjustments: All wiring terminals, pressure taps (1/8" NPT with plug), and burner adjustments are accessible from the top for faster commissioning.
• Contaminant Protection: Built-in internal inlet screen prevents pipe scale and sediment from causing valve failure or irregular gas valve manifold pressure.

Can this valve be used with 750mV millivolt systems?
No, the VR8345M4302 is designed strictly for 24Vac residential and commercial heating systems. Using it in a millivolt application will result in failure as the coil requires a standard 24V transformer output.

How do I configure this for Direct Spark or Hot Surface Ignition?
The valve includes an ignition adapter and a keyed jumper for the terminal block. Properly setting the jumper allows the internal circuitry to communicate correctly with your specific DSI or HSI control board.

What is the maximum pressure rating for this unit?
This valve is rated for a maximum inlet pressure of 1/2 PSI (14.0 in. wc). Always check the manifold pressure with a manometer after installation to ensure the regulator is set correctly for the appliance's data plate.
