    Plenum exits

    Is is okay if a plenum(5 duct taps, three 9"", one 8", one 7") have all of it's duct runs come out of only 2 sides? Reason I'm asking is that where the plenum will be going is blocked on 2 sides by walls up to a certain height, so that a 43" plenum would only have tap access on 2 sides. But if it was built taller to 76", the plenum could now have taps on all 4 sides. Thanks very much for any comments.

    shouldn't really matter, just if they come out and have to 180 back the other direction you are adding alot of equivilent length to the run, I would make the plenum taller so that the runs are tighter to the ceiling I guess myself but i can't see the job so can't say for sure how I would do it.
    You can't fix stupid
