DESCRIPTION

II. COMPONENT FUNCTION

The components for the lower and upper ovens are identical.

The following description covers the lower oven.

A. Conveyor

The conveyor is driven by a direct current electric motor operating through a gear reducer, (See Figure 1-6). The motor speed is controlled by a digital control. The stainless steel wire belt can travel in either direction and at variable speeds.

Note that only one oven section will control the speed of the conveyor (2 for a double tandem oven).

B. Gas Burner

Turning the heat switch to "I" will initially set up the oven purge circuit. After approximately 45 seconds, the solid-state ignition control lights a pilot by an electric spark.

After the pilot is lit, the main valve will open, permitting gas to go to the burner and heat the oven.

The main burner and pilot gas are extinguished when heat is off. This system permits the main gas valve to open only when the pilot burner is proven to be lit.

If the pilot flame does not light or a loss of flame occurs, the main valve closes and the red lamp is lit on the "RESET" switch. The "RESET" switch must be pushed to restart the ignition sequence.

Note that the gas burner of each oven section is independently controlled by that section's temperature controller.

C. Front Window

A front window provides access to each section of the oven for items which do not require full bake time, such as sandwiches, cookies, small items or cheese melting processes.

The window is also used for viewing items being baked and for cleaning.
