Per the following quick sketch, I'm considering making a more permanent vent set up for my MES40 which will reside inside my shop. Total length of the vent will be 4+ feet. Is there an advantage of going either A or B? This is looking at the smoker with the vent going out thru the exterior wall. Thus A will have 3 right angle elbows before it passes thru the wall, while B would have 2 right angle elbows. Which is better especially when thinking about creosote accumulation and drainage? I'm thinking A which would have a lower horizontal section which I could add some seepage holes for any possible creosote moisture.
