Hi pizzasalpper, welcome!
We've recently had a similar discussion
here .
My friend is a restauranteur who inherited a pizza oven when she purchased her place. After much experimentation and asking around, she found that the best solution for her was to start the fire with newspaper and kindling to light up the logs in the right side of her oven. This way, the fire (and its accompanying mess) is always accessible. I should mention that unlike you, she doesn't have anything wider than 25 cm to bake in there..
Hope this helps.
