DESCRIPTION

III. COMPONENT FUNCTION

A. Conveyor Motor and Conveyor Belt

The conveyor belt is driven by a variable-speed electric motor (Figure 1-7) operating through a gear reducer. The motor speed is controlled by a digital control. The stain- less-steel wire belt can travel in either direction at variable rates ranging from 3 minutes to 30 minutes; this is the time that a product can take to pass through the oven.

B. Blower Fan

The blower fan is located at the rear of the oven. This blower forces heated air through the air fingers. The BLOWER switch must be set to “ON” or “I” for oven warmup and baking.

C. Gas Burner

Turning the HEAT switch to “1” activates the oven purge circuit. After approximately 30 seconds, the solid-state ignition control lights a pilot burner by an electric spark. This system permits the main gas valve to open only after the lighting of the pilot burner is detected by the flame sensor.

If the pilot flame does not light or a loss of flame occurs, the main gas valve closes.

The main burner gas is extinguished when the HEAT switch is set to “OFF” or “O”.

D. Window

A window on the front of the oven permits viewing the items being baked and provides access to the oven for items that do not require full baking time, such as sandwiches, cookies, small items, or cheese-melting processes.
