Hey everyone, I have been thinking about doing this for a few years and I am planning on trying to do it in the next month or so. I want to be able to use my WSM out of the elements. Ideally I would like to use some type of ducting and a chimeny but with the WSM I dont think that will work very well so, I am considering purchasing a fan like to use on the wall nearest were I would use the smoker. I would then either keep the door cracked or install something like this on the other side of the garage for a fresh air inlet. I am wondering if you guys think the 560CFM fan would be enough or if I should go for a 1400cfm or higher exhaust fan. My garage is not very large. maybe roughly 15x15 if that, its a single car garage built in about 1950. What do you think? I dont really care if the garage smells like smoke, but I would like to be able to get a little heater out there and have our patio table out there in the cool months and play cards and keep an eye on the smoker without having to worry about poison gas or being choked by to much smoke.
