SECTION 1 - DESCRIPTION

I.OVEN COMPONENTS - see Figure 1-1.

A.Conveyor Drive Motor: Moves the conveyor.

B.Crumb Pans: Catch crumbs and other material that drop through the conveyor belt. One crumb pan is located at 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.
