I looked some tutorials but I'm unclear on when additional flappy louver cover needs to be installed?
Meaning, I have an "A" area of louvers maybe 4 feet across bottom built into the house and there is some frame there to work with. But can the fan blow through the existing louvers or does another hole need to be cut for autoflap louvers? I'm worried this would look silly from the outside. This is my first post and I'm not sure I'm a diy'er yet but I like learning.
