placement of chimney relevant to oven diameter

[wateetons]

Guys,
I'm building a 70 cm (27 inch) oven in The Netherlands. I blog about it here: pizzaoven | Wateetons It's in Dutch. Sorry. But the pictures are in International.

I have been finding massive amounts of answers on this forum. Thanks for that. I haven't yet found the answer to this question though: Is there an ideal placement for the chimney given a certain ovendiameter. The reason I ask is that I feel my ovendoor arch sticks out a bit much and I fear the chimney might be placed to far in front of the dome for it to work properly.
Any thoughts?

I should mention that picture no 2 does not accurately depict the ovens current state. The Dome (picture 1) is somewhat lower and i cut away the part if the arch that was sticking inwards.

This probably gives a decent view on the location an depth of the arch.
