Italforni Bull Ovens

Just opening using bottom deck. Working well, but suddenly bottom not cooking and back two spots blazing. Played with the bottom and top deck, but burning half bottom.
Cooked very well for two hours and…anyone have any ideas?

Hey Spinneria did you ever figure out the oven situation, I recently have been using the bull italforni and it drops temperature like crazy when we get busy for dinner. Any info would help
