each end of the conveyor.
C,D. Conveyor End Stop and Rear Stop: Prevent food products
from falling off the end or rear of the moving conveyor.
E. Conveyor: Moves the food product through the oven.
F. End Plugs: Allow access to the oven's interior.
G. Eyebrows: Can be adjusted to various heights to prevent
heat loss into the environment.
H. Window: Allows the user to see and access food products
inside the baking chamber.
I. Machinery Compartment Access Panel: Allows access
to the oven's interior and control components. No user-
servicable parts are located in the machinery compart-
ment.
J. Control Panel: Location of the operating controls for the
oven.
Not Shown:
K. Serial Plate: Provides specifications for the oven that affect
installation and operation.
L. Gas Burner: Heats air, which is then projected to the air
fingers by the blowers.
M. Blowers: Project hot air from the burner to the air fingers.
N. Air Fingers: Project streams of hot air onto the food product.
