Cone Assembly and Installation

Begin assembling the Cone by laying a Cone Panel 

(Item 1, Figure 3)

 on a couple of boards with the 

c-

shaped drain tab

 

(Item 2)

 towards the front 

as shown

. With the c-shaped drain tab toward the front 

(See 

Figure)

, insert the tabs of each Cone Panel into the Slots of the next and lay them down locking them in 

place. 

When all four Cone Panels are connected, stand the panels up on edge and curl the Cone around with the 
smaller diameter of the Cone up as 

shown below

. Assemble the final Panels together

 

and allow the Cone 

to take its shape. If the Cone is assembled correctly the Tabs should all be on the Inside of the finished 
Cone. Fasten the Cone Panels together with (4) 5/16 x 1/2" Hex Bolts Threaded in from the inside of the 
finished Cone 

as shown in Figure 4

Do not tighten down the Nuts at this time.

 Leave the Nuts loose until 

the Cone is attached to the Fan

.
