DESCRIPTION<br />
III. COMPONENT FUNCTION<br />
A. Conveyor Motor and Conveyor Belt<br />
The conveyor belt is driven by a variable-speed electric<br />
motor (Figure 1-7) operating through a gear reducer. The<br />
motor speed is controlled by a digital control. The stainless-steel<br />
wire belt can travel in either direction at variable<br />
rates ranging from 3 minutes to 30 minutes; this is the time<br />
that a product can take to pass through the oven.<br />
B. Blower Fan<br />
The blower fan is located at the rear of the oven. This<br />
blower forces heated air through the air fingers. The<br />
BLOWER/Heat switch must be set to “ON” or “I” for oven<br />
warmup and baking.<br />
C. Electric Heaters<br />
There is one heater element mounted on the inside of the<br />
left panel. The element is connected to an electrical<br />
control which is energized by the temperature controller.<br />
If the pilot flame does not light or a loss of flame occurs,<br />
the main gas valve closes.<br />
The main burner gas is extinguished when the HEAT<br />
switch is set to “OFF” or “O”.<br />
D. Window<br />
A window on the front of the oven permits viewing the items<br />
being baked and provides access to the oven for items that<br />
do not require full baking time, such as sandwiches,<br />
cookies, small items, or cheese-melting processes.<br />
E. Cooling Fan — See Figure 1-8<br />
The cooling fans are located in the back of the oven.<br />
These cooling fans draw air through its grille, blowing it<br />
through the blower motor compartment and the control<br />
compartment into the oven top and exhausted out the front<br />
louvers.<br />
F. Air Fingers and Blank Plates - See Figure 1-9<br />
F1. Air Fingers<br />
An Air Finger Assembly is made up of three parts:<br />
1.Outer Plate - The Outer Plate is the removable covering<br />
with tapered holes, which direct the air stream onto the<br />
product being baked.<br />
2. Inner Plate -The perforated Inner Plate is vital in forming<br />
the unique air jets. It must be assembled into the manifold<br />
with its holes aligned with the holes of the outer plate.<br />
3. Manifold - The Manifold is the assembly which slides<br />
on tracks into the oven plenum.<br />
