Resideo VR8305M3506 Dual Direct Ignition Gas Valve

Product Description

The RESIDEO VR8305M3506 is a dual direct ignition gas valve designed for use in residential and light commercial gas heating equipment. It operates on 24 volts AC and controls the flow of gas to the burner in response to a direct ignition signal from the system control board. The valve features a 1/2 inch inlet and 3/4 inch outlet configuration with a standard opening design and a factory-set pressure regulator at 3.5 inches water column. Licensed HVAC technicians install this valve as a direct replacement in gas furnace and heating appliance applications.

This valve is suited for residential gas furnaces and heating appliances that use dual direct ignition control sequences. The 1/2 inch x 3/4 inch inlet-to-outlet sizing is a common configuration in standard residential gas appliances. The 3.5 inches water column pressure regulator setting aligns with typical natural gas appliance requirements. This part is sold individually and is typically installed by a licensed HVAC or gas appliance technician.
