2.2 INSTALLING AFR 
 (Tile or Cement Roofs from 3:12 to 8:12)
NOTE: This installation requires the purchase of the QuietCool 
Secondary Flashing accessory (part number FLA-SEC-3743)
  NOTE: When applying weatherproof sealant, be sure to use a 
generous amount to create a watertight seal.
1.  Determine in which area you would like to install your QuietCool 
AFR.
2.  From inside the attic, nd the center point between the two roof 
rafters and mark it as the center of the fan hole. Partially insert a 
screw into the center point mark. 
3.  Go to the roof and nd the area in which you marked your fan hole 
with the screw. Move the tiles out of the way to expose a large area 
around where you will cut the fan hole. (see Figure 2.2A)
4.  Using the screw as a reference point and the provided template, 
trace out the 17 1/4” diameter circle. (see Figure 2.2B)
5.  Use a saw to cut out the traced hole pattern from the roof decking. 
Remove the cut out decking material from around the hole as 
needed. (see Figure 2.2C)
6.  Apply weatherproof barrier to the roof.
7.  Remove the fan hood for easier installation. This will help you line up 
the fan to the hole in the roof and shape your tile.
8.  Position the fan so that it is centered with the vent hole. 
9.  Lifting the fan unit up at an angle, apply weatherproof sealant to the 
bottom side of the fan unit. This will help keep the fan in place and 
create a watertight seal. (see Figure 2.2D)
10. Using a minimum of 8 roong nails, nail the fan to the roof through 
the primary ashing, securing the fan to the roof. To prevent leaking, 
be sure to apply weatherproof sealant on the nail heads. (see Figure 
2.2E)
11. Once complete, apply more weatherproof barrier around the fan unit 
on top and bottom. Be sure to apply a generous amount of weather 
proof sealant underneath the weatherproof barrier and install with 
roong nails. (see Figure 2.2F)
