B. Blower Fan

The blower fans are located at the rear of the oven.

These blowers force heated air through the air fingers.

The BLOWER switch must be set to “ON” or “I” for

oven warmup and baking.

C. Gas Burner

The gas burner is located inside the right control box

and is controlled by the temperature controller.

D. Cooling Fan

See Figure 6 and Figure 7.
The cooling fan is located in the back of the oven. The

cooling fan draws air through its grille, blowing it

through the blower motor compartment and the control

compartments, then into the oven top. The air exits out

the front louvers.
