Schneider Electric (Barber Colman) 20-684 Diaphragm

The Honeywell VR8345M4302 Universal Electronic Ignition Gas Valve is a technical powerhouse designed to replace a massive range of 24 Vac intermittent pilot, direct spark ignition (DSI), and hot surface ignition (HSI) gas controls. As a veteran technician, you know the value of a single truck-stock item that handles capacities from 30,000 to 415,000 BTU/hr. This standard opening gas valve features a 3/4" x 3/4" NPT inlet and outlet, including two 1/2" reducer bushings and a LP conversion kit for field flexibility. The compact design with a 4-inch swing radius and 0° to 90° mounting capability ensures it fits into the tightest furnace vestibules. With a 3.5" W.C. pressure regulator setting and top-access wiring terminals, this dual automatic valve streamlines installation while maintaining high-performance safety standards for natural and liquid propane gas systems.

• Extreme Versatility: Replaces common Honeywell, White-Rodgers, and Robertshaw gas valves across IP, HSI, and DSI platforms.
• High BTU Capacity: Rated up to 415,000 BTU/hr, making it suitable for residential and light commercial applications.
• Simplified Wiring: Features clearly marked, keyed terminal blocks for quick jumper selection between ignition types.
• Contaminant Protection: Includes an internal inlet screen to prevent gas line debris from fouling the servo pressure regulator.
• Multi-Poise Mounting: Can be installed at any angle from 0 to 90 degrees from the upright position.

Is the VR8345M4302 compatible with LP gas out of the box?
It is factory-set for natural gas but includes a comprehensive natural to LP conversion kit in the box for immediate field adaptation.

Can this replace a standing pilot gas valve?
No, the Honeywell VR8345M4302 is specifically engineered for electronic ignition systems and is not a direct replacement for 750mV or standing pilot controls.

What is the maximum inlet pressure rating?
The valve is rated for a maximum inlet pressure of 0.5 psi (14.0 in. W.C.). Always verify your supply pressure before final commissioning.
