Hello

Is it OK to vent a dryer vertically into an attic crawl
space instead of horizontally thru an exterior wall to the
outside? - paul

Generally I would say no. There may be some exceptions where that
craw
space is vented a lot better than most and you live in a dry environment.
Otherwise, you are going to add moisture to an area you want to keep as
dry
as possible. Vent to the outside. I might add that you would also be
depositing lint down there.

Also, there will be an accumulation of lint in the hose, which will not be
pushed all the way up to the outlet, causing a fire hazard.
