this Scuttle steam is beyond all of the takeoffs save one on this supply plenum, The one rin of duct that is actually being fed is a 100 Sq.Ft. powder room.
It's kind of hard to figure out what you are showing us, especially with the HUGE picture. You should resize that and re upload it.
If I am seeing this correctly, that looks like a Totaline humidifer? Installed at the END of the plenum AFTER all the duct runs????
I wonder how that works. It's probably soaking the end of that plenum box pretty good.
