I am building a 36" oven from the Forno Bravo plans. In looking at the design I am wondering why there are no air vents in the sides of the oven. Has anyone tried installing a pipe with damper in the sides of the oven? Is there a reason for not doing something like that? It just seems like having a way to control air flow could offer increased temperature control for the oven. With side air vents, I could close the door and control air using the dampers...air comes in from the sides and out the chimney.
