Rotate the side pieces so that the holes along
one edge line up with the holes on the top
piece and the flange is on the inside of the
rain hood.
Attach the side pieces to the top of the hood
using the provided screws and attached the
side pieces to the end of the unit through the
flange.
Apply silicon caulking along the top and both
sides of the rain hood. Take care to seal the
top corners where the rain hood attaches to
