I used a 4 inch hole for the exhaust that I do have adjustment for and 2) 1 1/2 pipe elbows for inlets that are also adjustable. I am able to reach and hold temps from under 200 to over 700 degrees ( the gauge does not read above 700 but the needle goes way past). So yes it does work, but for 350 degrees and lower you will need to control the exhaust. You have to be able to control the air flow at both ends with an opening that large for the exhaust. I do use that large opening to check on the stuff in the smoker without having to lift the lid.
