mounting frame. Insert the mounting frame through
the ceiling opening and let it rest on the back side of
the ceiling material, directly over the ceiling opening.

the framing member. Nail or screw mounting frame
in place. Extend the mounting frame to the opposite
framing member, and nail or screw in place.

a short length of 4” flexible duct. Existing 3” ductwork
will require a 3” to 4” transition.
