The Thermostat is a hydraulic valve that has two separate gas lines and a sensing bulb (see Figure 4-2 ). The pilot gas line maintains a pilot flame in the oven, and the main gas line provides gas to the oven safety valve. The sensing bulb is a mercury-filled tube that controls the thermostat to open or close the gas lines, and release gas from the manifold pipe to the oven safety valve. The thermostat operates based on the temperature it senses in the oven cavity.

The Oven Safety Valve is also a hydraulic valve that has a gas inlet line and a gas port that is metered by an orifice hood (see Figure 4-3). It also has a mercury-filled sensing bulb that controls its operation. The safety valve has one function: to release gas to the oven burner from the thermostat.
