Hi Mike,
Do you build oven at home or in that land with the beautiful lake?

The vent has to be deeper than 5 inches (12.7cm) for it to drag all fumes nicely up and not making oven outside front black. Below link takes you to posting with more on this, subject "Help smoke problem", more people replied to it I think. Oven will cook well of course but not 100% of all smoke would be directed up to the hot air passage and to the chimney size.

If you didn't put the hearth slab on yet, from the existing ground concrete slab size you could build up concrete blocks offset each of them popped out 3" - 7.5cm and gradually extending the hearth slab 9" - 23cm backwards. Then the same with the rear building brick wall. How far are you? r
