Your vents or intakes are to feed air to your fire. Without air the fire won't burn! and you want a small hot fire i have 2 4 inch intakes on my cooker with 2 6 inch exhaust pipes and mine is a 250 gallon cooker. I went a little over kill could have got buy with 1 6 inch exhaust..
but hey.. had the pipe so was like.. well chit lets slap it on there! lol You want your intake to be below your fire grate so the air feeds the fire from the bottom and then that heated air/smoke goes into your cooking chamber.. Now your Cookin'!
