Ring and Cone and secure with 5/16 Flange Nuts (Item 3). Only hand tighten the Nuts at this time. Working around
the Fan Orifice from inside the fan, in a circular motion Slide the Cone over the Fan Orifice. The Cone will Fit snug.
Use the Bolts previously threaded through the Ring and Cone and the 5/16 Flange Nuts to secure the bottom of the
Cone to the Fan as shown. Use a Level and rotate the Cone until the Door center rail is Vertical (See Figure). Now
