CE Units Built Through April 1999
CE units built through April 1999 are equipped with a shield assembly in front of the blowers. An
air shutter plate on the face of the shield assembly regulates the amount of airflow to the blower in-
take. To adjust the shutter plate, loosen the locking screws and slide the shutter to the left or right as
necessary to obtain a bright orange-red glow. Carefully hold the shutter plate in position and tighten
the locking screws.
