The Resideo VR8300A4516/U is a single-stage, 24 Vac standing pilot gas valve engineered for reliable operation in gas-fired residential heating appliances. Featuring 3/4in x 3/4in inlet and outlet connections with a factory pressure setting of 3.5in WC, this combination gas control valve accommodates appliance capacities ranging from 30 to 300 cfh, supporting natural gas applications up to 300,000 BTU/hr maximum at 1in WC with a 30,000 BTU/hr minimum requirement. This valve integrates multiple safety and operational functions into a single compact assembly, including an automatic safety shutoff mechanism, manual isolation valve, two solenoid-operated automatic valves, integral pressure regulator, and pilot adjustment capability. The first solenoid valve opens upon thermostat call for heat and closes when the heating demand ends, while the second solenoid provides positive shutoff protection. The compact design facilitates installation in confined spaces typical of residential furnace applications. The VR8300A4516/U is suitable for standing pilot systems and supports conversion between natural gas and LP gas configurations using appropriate conversion kits. Its combination design eliminates the need for multiple separate components, reducing installation complexity and footprint requirements while maintaining essential safety features and operational control. This replacement valve is ideal for HVAC contractors, technicians, and facility managers maintaining or upgrading residential heating systems. Its proven design and comprehensive integrated functionality make it a dependable choice for furnace gas valve replacement applications.
