The ceiling vent changes how heat behaves inside the oven. If it’s open, heat escapes straight up the chimney. Close the ceiling vent for a low, slow
cook and for a smokier taste to your food. When the ceiling vent is closed, smoke will gather for longer in the oven body before escaping from the
side air channels.
Ceiling vent: When this is closed, it will reduce air flow and
allows hot air to gather inside the oven for longer.
Side air channels: These allow hot air to escape when the
chimney vent is open and ceiling vent is closed.
Caution:
Do not adjust the ceiling vent while Pro is hot.
