rough opening (See Figure 1). Also check that the bottom plate of the rough opening is flat (not bowed) as shown
in Figure 2.
After putting the Fan in the rough opening, check that it is square by measuring from corner to corner of the Fan

the Fan Blade Tips and the Shroud (See Figure). If there is not 1/8" Blade Tip Clearance see page 2.
