Been working on this for a few months now and have a few questions. It's 60 gallon tank and 20"x20 firebox but my question is exhaust. The calculator says I need 6" exhaust that is 10" tall but I read maybe here I can't remember that if I use 2 stacks instead of one in center it will help with hot spots but that I can't just use 2 3" pipes so how do you figure the size on 2? Trying to get some pics to load but will have to wait until I leave for town
