Replacement gas control valve from Resideo (Honeywell Home) for Bradford White water heaters with 1 inch insulation, part number WT8840A1000/U.

The gas control on a storage water heater is thermostat and safety shutoff in one body. It reads tank temperature through a probe in the wall of the tank, opens the burner when the water drops below setpoint, and closes on a loss of pilot or on a temperature it will not allow.

Match the control to the tank, not just to the thread. Water heater gas controls are specific to the manufacturer, the insulation thickness and the emissions rating, because the probe length and the shutoff logic differ between them.

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.
