The oven uses a Single Safety Valve that is bimetal-operated (see Figure 4-16). It has one gas inlet and one gas outlet, for the combination Bake and Broil burner. The safety valve uses an electrically-operated device at the gas outlet to control the gas flow to the oven burner. The device consists of an electric heater coil wrapped around a bimetal strip. One end of the bimetal is riveted to the plate of the valve. The other end has a rubber seat attached to it that covers the gas outlet. At room temperature, the spring force of the bimetal presses the rubber seat against the gas outlet.

Gas is available at the safety valve at all times, but can be shut off by a manual shutoff valve on the regulator (see Figure 4-17).
