Honeywell VR8300C4506 Valve

The Honeywell VR8300C4506 is a high-capacity dual automatic combination gas valve designed for 24 Vac gas-fired standing pilot appliances. This step-opening control is engineered to manage natural gas flow in systems with capacities ranging from 30,000 BTU up to 290,000 BTU at a 1-inch pressure drop. It features a 3.5" water column full rate setting with a 0.9" w.c. step, providing a smooth transition to full burner ignition and reducing mechanical stress on the heat exchanger. As a technician’s go-to standing pilot gas valve, it incorporates a manual valve, two automatic operators, and a servo pressure regulator in a compact, 3/4" x 3/4" NPT straight-through body. This model serves as the direct replacement for 81660242 and is compatible with ECO connectors. The kit includes two 3/4" x 1/2" reducer bushings, offering flexible installation for various manifold configurations. All adjustments and 1/4" quick-connect terminals are top-accessible for efficient field servicing.

• Dual Safety Shut-off: Meets stringent code requirements with two automatic valves for redundant safety during operation.
• Step-Opening Regulation: Ensures quiet burner ignition and stable performance across local gas supply fluctuations.
• Universal Mounting: Can be installed at any angle from 0 to 90 degrees from the upright position for tight cabinet clearances.
• Complete Replacement Kit: Includes reducer bushings to adapt to 1/2" piping, making it a versatile Honeywell gas valve replacement.

Is the VR8300C4506 compatible with LP gas?
This specific model is factory-configured for natural gas. While some VR8300 series valves support field conversion, always verify using a Resideo-approved conversion kit before switching fuel types.

What are the electrical requirements for this valve?
The valve operates on a standard 24Vac gas control circuit (60 Hz) and utilizes 1/4 inch male quick-connect terminals for wiring. The thermostat heat anticipator should be set to 0.7 A.

How do I handle the Lite-Rite lighting sequence?
The three-position manual knob (OFF-PILOT-ON) requires the reset button to be depressed only while in the PILOT position. This integral safety feature prevents main burner gas flow until a thermocouple signal confirms the pilot is established.
