Hi, I am hoping someone has some advice for me. We are remodeling our basement, and our washer and dryer are down there. The old owners of the house previously had the dryer vent into a crawl space underneath the house. We got a new washer and dryer and converted to a gas dryer (since we had a gas line) but the nearest outside wall is 20 feet away (since most of what is behind the wall is an extension with crawlspace underneath). We used rigid galvanized pipe and ran it along the wall, and as a result I probably have 2 elbows and maybe 15 feet of horizontal duct work currently behind 2x4s (we have not drywalled yet). The last 4 feet or so are exposed where it vents out (we are leaving a section of the basement unfinished). I purchased a dryer booster fan as well was a lint trap since the duct is very long. I noticed with the new gas dryer that the pipe gets a lot hotter than when we had our old electric dryer. Now my concern is putting drywall over the wall where a lot of the duct runs. Is this a bad idea? Not sure what else I can do, my options are limited since we can't move the washer across the room (consulted a plumber and he said its not possible being that the washer is near the waste line).
