I want to make a vent on top my Masterbuilt wide propane smoker. the vent in the back doesn't seam to vent very well at all.
after a few trips to local places like ACE, Menards and a fireplace store I have no idea what to make vent/chimney out of or how big.
what dia? how long of a pipe? not even sure how to mount or seal it either.
I would appreciate any advice.
