Hi Guys, Not sure if they changed something in the design of the Char Griller (Smoke'n pro model) smoke stack, but now they have a flared out lip at the base of the stack. I went out and bought a 3" dryer vent yesterday and spent the better part of an hour trying to find a way to make it fit over that lip, no go! Has anyone else had an issues with this / found a way to get around it? From what I can tell I pretty much have 2 options, go with a 4" vent and loose more real-estate in body, or break out the angle grinder and take that lip down. If you guys have any advice i'd really appreciate it.
