    Hey y'all, doing my first smoker build, going slow but making some progress.... It is a 200 gallon propane tank, the firebox is 30"wide 30" deep and 24" tall. Due to design flaws (learning experiences) I need to build a rectangular stack, neither Feldons or the alien calculator talk about a rectangular stack.... Hoping someone can help me determine the size, also it really needs to be 4"x however wide, but only 4" in one direction.... Also how deep into the cc does it need to extend? Thanks y'all I appreciate any and all help

  3. Good evening,    Rectangular Stack I presume    A 200 gal tank needs 924 cu in of vol.   (Dave suggest a little more)

    A 4 x 8 in piece of tubing needs to be at least  38.5 in to achieve 924 cu.in.

    Run double stacks so you can have control of side to side

    Thanks Dave, didn't see anything for square rectangle till I re read it.... Must have skimmed over. I say it's 200 gallon because of id plate but it's a little bigger going off of dimensions, probably gunna go 4x9" or 4x10" and going 36" above cc.... But still don't know how far or how to figure out how far to extend into the cc... And Clint I like the idea behind 2 stacks, still contiplating if I wanna go that route..... Again I appreciate all help and advise, here are some pics, it's a slow process cause of budget, using scrap material, and no shop, but one day she will be done
