First, congratulations on your decision to put your flue in the front. It's the proven technology, and will make for a better oven.

You do want a chimney in the oven. At start-up your oven will produce a lot of smoke, and that's when you have to do most of the face-to-oven work of building the fire. You can build an oven with no flue, but you will have a lot of smoke in your face, and the front of your oven will be covered with soot.

In addition, the flue will improve air-flow, and will get your fire going more quickly with less frustration. That's why serious boilers have tall chimneys: the draft supercharges the firebox.
