Powerhouse Series II Recirculation System:
1. The impeller pulls heated air in from the blower box and directs it up through the exhaust chimney.
2. The adjustable exhaust flap directs desired amount of heated air back into the oven chamber via the
exhaust return tray. The remainder of the exhaust exits through the top of the chimney.
3. Heated air in the oven chamber is pulled down through the suction plates and into the blower box by
the impeller.
4. Fresh air is pulled through chambers between the outer and inner walls and into the blower box. This
recovers the otherwise wasted heat from the inside walls of the oven.
5. Oven air and heated fresh air are mixed in the blower box and pulled into the impeller for exhaust.
