Should a flame outage occur the control will close the main gas control valve within 0.8 seconds and attempt to reignite the pilot.

D. Electric Heaters (Electric Oven Only)

There are six heater elements mounted on the inside of the rear panel. Each element is connected to a separate electrical contact which is energized by the temperature controller.

E. Front Window

The front window is used for viewing items being baked and provides access to the oven for items which do not require full bake time, such as sandwiches, cookies, small items or cheese melting processes.

F. Cooling Fan

A cooling fan is located in the back of the oven. This cooling fan blows cool air in through the machinery compartment across the fan motor and conveyor motor and control cabinet. The air is then exhausted through the side of the cabinet and also out the back of the oven compartment. Refer to Figure 1-6.

Another cooling fan is located in the bottom of each control box. Air is drawn in through the louvers in the rear of the control box and out through the fan. Refer to Figure 1-4.

B. Fan

The fan is located at the rear of the oven. This fan forces heated air through the fingers. The fan switch has two positions and must be "on" for oven warm up and bake and for the conveyor to run.

C. Gas Burner (Gas Oven Only)

With the heat and blower switches ON the gas burner

heats the air as the air enters the main blowers toFigure 1-6. Cooling Fan maintain the set temperature. The burner flame is ignited

and monitored by a solid state burner control device.
