GEN3 CMA/CMD Model Series Fans

Getting Started
Your Attic Breeze curb-mount solar attic fan is designed for easy installation with metal roofs, tile roofs, or roofs featuring
other high-prole materials where a roof curb is required for proper installation. If installing our products on a composite
shingled roof or a simliar low-prole roof type, please contact Attic Breeze for information on our self-ashing fans
designed for those roof types.
Safety Information
Safety precautions should be taken when performing the roong work described in this installation guide. You can
signicantly reduce your risk of danger by following the below recommendations:
• Do not perform roong work in wet or windy conditions
• Tie-off both yourself and your equipment when working on steep pitched roofs to avoid falls
• Wear safety glasses and protective gloves when using power tools
• Always wear slip-resistant shoes when working on the roof
• Do not cut through any rafters or structural members of the roof during installation
• Leave the solar panel covered until your installation is complete
Choosing the Right Location
Choose a location to install your solar attic fan that allows for balanced air ow throughout the attic space. The solar
fan should be installed roughly centered on the roof and three feet below the ridge line. For optimum performance,
choose an area on the south side of your roof that is not shaded or blocked from the sun for extended periods
throughout the day. If a location on the southern side of your roof is not available, you may raise the solar panel
mounting bracket and face the fan unit toward the south for better sun exposure. Your solar attic fan should not be
installed any closer than within 10 feet to an existing passive vent, ridge vent, or additional fan unit.
Ventilation Requirements
In order for your Attic Breeze solar attic fan to operate at maximum performance,
your attic must have enough intake ventilation (net free area) to support the
amount of air that your fan is moving. The minimum recommended amount of
intake ventilation for your product model is shown in Table 1. Your installation
should either meet or exceed these recommendations for optimum fan
performance. If you need assistance determining the proper amount of intake
ventilation for your home, please visit our website for more information.
Your local building code may require specific fasteners or anchoring systems not discussed in this installation guide. If
installing this product in an area of either Florida or Texas that has been designated as a high velocity wind zone area,
review applicable building code requirements for additional installation instructions.

What's Needed

Installing the Fan
Begin by removing roof tiles in the area where the roof curb 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.
If your roof has 24" on center rafter spacing, nd the center point
between two rafters and mark it as the center of the vent hole. For
roofs with 16" on center spacing, mark the rafter itself as the center
of the vent hole. Using the center point mark as a reference point,
trace out a 20" x 20" square around the center point. Next, use
a reciprocating saw to cut out the traced pattern from the roof
decking. Remove the cut out decking material from around the
hole as needed.
Step 1 - Cut the Hole
Figure 1 - Cutting the Hole
ATTENTION: DO NOT CUT THROUGH ANY RAFTERS OR
STRUCTURAL MEMBERS WHILE CUTTING THE VENT HOLE.
ONLY CUT OUT THE ROOF DECKING.
Install your Attic Breeze AB-004 roof curb installation kit per the
included instructions. When complete, please proceed to the
next section. If installing an as-built or third party roof curb box
and ashing system, the roof curb should be constructed with
dimensions of 23 ½” x 23 ½” x 6” and designed to support a weight
load of at least 30 LBS. Please consult your roof curb provider for
proper installation and ashing instructions.
Step 2 - Install the Roof Curb
Figure 2 - Installing the Roof Curb
If your Attic Breeze fan is equipped with a unit mounted (attached)
solar panel, please proceed to the next section. For Attic Breeze
models featuring a remote mounted solar panel, the solar panel
will be mounted prior to installation of the fan unit. Begin by
Step 3 - Remote Mounted Solar Panel
If additional power cable length is needed for your installation, Attic Breeze offers a 25 foot extended power cable as an
available option.
Route the power cable through the attic, starting from the vent hole area to the location where your remote solar panel
will be installed and secure the power cable in place. The power cable may be routed out of the attic by bringing
the cable through an existing passive vent, penetrating a gable wall and running the cable along the roof eve, or
simply routing the power cable directly through the roof. When making any wall or roof penetration, caulk around the
penetration using a roof-grade weatherproof sealant. Install the solar panel mounting brackets per the instructions
included with your specic Attic Breeze bracket kit. Plug in the power cord to the connector on back of the remote solar
panel and securely mount the solar panel/bracket assembly as required to your roof or structure.
Mount your roof curb to the framing structure or decking of the roof
as required. Remove battens as needed in order to mount the roof
curb ush to the decking. Position the roof curb over the vent hole,
squaring the curb with your roof tiles. Securely fasten the roof curb
in place and replace roof tiles as needed up to the installed curb.
Secure the tiles as needed and ash in the roof curb installation as
required for your choice of ashing system.
locating the power cable included with your Attic Breeze solar attic fan. Make sure the power cable is long enough to
reach the location where the remote solar panel will be installed.

Figure 3 - Mounting the Fan
Adjusting the Solar Panel
The solar panel on your Attic Breeze solar attic fan may either be left down in
the horizontal mounted position as received from the factory, or the solar panel
bracket may be raised to pivot the solar panel toward the south in order to get
better sun exposure.
DO NOT OVER TIGHTEN THE SET BOLTS! You may damage your bracket if
too much torque is applied to the set bolts.
Warranty Registration
YOUR WARRANTY MUST BE REGISTERED WITHIN 90 DAYS OF
INSTALLATION. Please visit our website at www.atticbreeze.net to
register your warranty.
Remove all packaging material and tape from your fan. Position the fan so that it is centered with the vent hole and
allow the control cable to hang freely from the bottom of the fan unit. Locate the control switch (red bag) included
with your solar fan, or if installing a Breeze Mate® control system, please follow the instructions included with that
product at this time. Plug the control switch (or Breeze Mate® cable) into the control cable 4-prong plug. For models
featuring a remote mounted solar panel, plug the power cable from the solar panel into the 2-prong plug on the
control cable.
Step 4 - Mount the Fan
ATTENTION: KEEP THE SOLAR PANEL COVERED DURING INSTALLATION.
After the control switch is connected, your Attic Breeze solar fan may begin
operating immediately when exposed to sunlight.
Caulk around the top of the roof curb box using the weatherproof sealant and
position the fan over the roof curb (see Figure 3). Align the fan unit with the
vent hole so that the sticker "INSTALL THIS SIDE TOWARDS GROUND" is facing the
correct direction. The fan unit can also be turned 90 degrees from this postion
to allow for better solar panel sun exposure if needed (ex. East or West facing
roof orientation).
With all fan cables connected and hanging inside the roof curb, mount the fan
unit over the roof curb box and ashing, securing the fan to the sides of the roof
curb box using three self-tapping screws per side. Apply additional sealant to
weatherproof the installation as needed.

ATTENTION: Do not raise the solar panel if installing this product in an
area of either Florida or Texas that has been designated as a high velocity
wind zone area. The solar panel must remain in the flat horizontal position
due to building code requirements.
