With all fan cables connected and hanging inside the vent hole, slide the fan unit underneath the shingles until
the fan reaches the top of the hole. Secure the fan flashing to the roof. Finish caulking around the fan and
flashing it into the roof to make a nice seal.
(See Figure 2.2E)

Your install is complete!

2.3 Installing RM (Roof Mount) model fans
1. Determine in which area you would like to install your QuietCool Roof Mount Fan. (See Figure 2.3A on pg. 7 for
assistance in figuring out how to install the 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.
IMPORTANT:
If you are installing the RM fan as a ducted fan, it’s time to find the exact location for
your ceiling box and grille using a stud finder. Locate the wall studs and mark the location for the
box to be installed. Minimum of 20” clearance required. Make sure the duct will fit between the fan
location and the ceiling box location. Using a drywall saw, cut out the drywall.
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 2.24)
3. Go to the roof. Using the screw as a reference point, trace out either a 14” (RM ES-1100) or 16” (RM ES-2200)
diameter circle.
NOTE: The RM ES-2200 will only fit 24” on center.
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. 4)
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. 4)
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. 4)
