THE OVEN BURNER SYSTEM

STANDING PILOT IGNITION

The complete Standing Pilot Ignition System (see Figure 4-1) is controlled by two very important mechanical components. The first is a thermostat that is mounted on the manifold pipe and accessible to the customer, and the other is an oven safety valve that controls the gas flow into the oven burner. If either of these components is not working properly, the system will not function. The burner, air shutter, and venturi are also critical components, and work the same as on the cooktop burners that were discussed in Section 3.
