"Wiring box" may mean the electrical box in the ceiling. I have hung a
ceiling fan with the extended dealie, any ceiling fan install is a pain
in the a$$. I do not mean this to sound condescending or pedantic, but
you may want to find a neighbor or friend who's more familiar with the
electrical esp if the documentation is not very good.

Also don't put it on a dimmer switch unless you have the right kind.
