Resideo VR4300A4502 Valve
The Resideo VR4300A4502 is a robust 3/4 inch NPT dual automatic combination gas valve designed for 120 Vac standing pilot applications in high-capacity atmospheric boilers and commercial furnaces. Built for reliability in demanding environments, this standard opening gas valve manages BTU capacities from 30,000 up to 300,000 BTU/hr. It features a single stage design with a straight-through flow pattern and a factory-set 3.5 inch water column outlet pressure. The integrated 1/8" NPT inlet and outlet pressure taps allow for precise field adjustments using a manometer. This versatile gas control includes a natural gas to LP conversion kit and multiple reducer bushings (one 1/2" x 3/8" and two 3/4" x 1/2"), ensuring seamless field replacement across various pipe schedules. The 1/2 PSI pressure rating and safety shutoff mechanics make it a staple for technicians maintaining legacy standing pilot systems that require a high-limit interface and reliable pilot gas flow control.
Key Benefits
- Versatile Piping Options: Includes 1/2" and 3/8" reducer bushings to accommodate different manifold sizes.
- Field Convertible: Comes standard with a LP conversion kit for switching between natural gas and propane applications.
- Simplified Diagnostics: Features 1/8 inch NPT pressure taps with plugs for quick inlet and outlet pressure verification.
- High Capacity Range: Supports a wide output range up to 300,000 BTU, making it suitable for larger residential and light commercial equipment.
- Standardized Installation: The 3/4 x 3/4 inch straight-through flange design ensures compatibility with standard gas manifolds.
Common Questions
Is the VR4300A4502 compatible with intermittent pilot systems?
No, this valve is specifically designed for standing pilot ignition systems. For electronic or intermittent ignition, a different VR series model would be required.
What is the electrical requirement for this gas control?
This model operates on 120 Vac, 60 Hz power. Ensure the transformer and thermostat circuit match these voltage requirements to avoid damaging the internal operator.
Can this valve be mounted in any orientation?
It is recommended to mount the valve 0 to 90 degrees from the upright position. Avoid mounting upside down to ensure the internal regulator and pilot gas flow function correctly.
