Hi ! thebuzman,
I am a Chef & own a restaurant and use GARLAND convection ovens; which I have been using for many years " The Best as far as I am concerned ! ! I am now installing a Comstock-Castle GAS Pizza Oven Model 2P031 . It will be vented out as so to aid in the smoke output for different types of pizzas being made . Yes ! I would vent out ( Forget that smoke filter !!! ) I have it in my restaurant and thats only good for Cig. Smoke ! Trust me !
