Choosing the Right Location

Choose a location to install your QuietCool roof mounted fan that allows for balanced airflow throughout

the attic space. We always recommend the fan to be installed centrally located on the roof three feet

below the ridge line. This will allow you to access the fan very easily. Your roof mount fan should not be

installed any closer than within 5 feet to an existing passive vent, ridge vent, or additional fan unit.

IMPORTANT: DO NOT CUT THROUGH ANY RAFTERS OR STRUCTURAL MEMBERS WHILE CUTTING THE VENT

HOLE. ONLY CUT OUT THE ROOF DECKING.

2.2 Installing AFR (Attic Fan Roof) model fans

1. Determine in which area you would like to install your QuietCool Attic Roof Mount Fan.

IMPORTANT: After choosing the location where your roof mount attic fan will be installed, find the

closest rafter to that location and determine if your roof has either 16” on center or 24” on center

rafter spacing.

2. Find the center point between the two rafters and mark it as the center of the vent hole. Partially insert

a screw into the center point mark.

NOTE: If you have a tile roof, you will need to move the tiles out of the way before tracing and cutting.

(See Figure 2.2A on pg. 6)

3. Go to the roof. Using the screw as a reference point, trace out a 16” diameter circle.

4. Use a reciprocating 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 2.2B on pg. 6)

5. If you have a shingle roof, insert the reciprocating saw sideways between the shingles and roof decking.

Starting at the 3 o’clock position of the vent hole, begin cutting in a sweeping motion under the shingles,

cutting through any roofing nails or staples. Continue cutting counterclockwise around the vent hole

until reaching the 9 o’clock position. Using a roofing knife, cut a 4 inch horizontal slit in the shingles at

the 9 o’clock and 3 o’clock positions of the hole, allowing the fan’s flashing to slide underneath the

shingles.

6. Apply weatherproof material to the roof. (See Figure 2.2C on pg. 6)

7. Position the fan so that it is centered with the vent hole and allow the power cord to hang freely from

the bottom of the fan unit. The power cord comes in 20 ft length. Make sure your fan is close enough to

an outlet in your attic. (See Figure 2.2D on pg. 6)
