Adjusting Air/Gas Mixture
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 intake.
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.
