Fan Installation Tips

•The fan must be installed so air is pulled from the rear of the oven and blown into the control area. The arrow on the fan body indicates airflow direction and should be pointing toward the controls.

•Ensure the fan is seated squarely against the air tube and the oven bottom.

•The air deflector should be angled upward at approximately 30 degrees to properly direct the airflow.
