Description
The VR8204A2076 is a single-stage gas control valve from Resideo (Honeywell Home) for intermittent pilot appliances, 24 Vac coil.
The gas valve is the component that admits fuel to the burner and shuts it off. It carries the main shutoff, the pressure regulator that holds manifold pressure steady as supply pressure varies, and the safety interlock that keeps gas off until the control system has proved it is safe to light.
Intermittent pilot lights the pilot only when heat is called for, proves it, and then opens the main valve. Nothing burns between cycles, which is the fuel saving over a standing pilot, and the ignition module watches the flame rod the whole time the burner runs.
The valve is standard opening. A slow-opening valve ramps the burner up over a couple of seconds to soften the light-off; a standard-opening valve goes to full rate at once. Match the opening rate of the valve coming out — this is one of the differences that does not show on the outside of the body.
Gas appliance safety. A gas valve must match the appliance it is fitted to — ignition system, capacity, inlet pressure and gas type. Replacement is work for a licensed gas technician, and the appliance manufacturer's parts list is what decides the correct valve, not the physical fit of the threads. If the replacement does not match, the appliance can fail to light, fail to prove flame, or overfire.
