Installation Instructions (continued)
Step 2 - Attic Requirements: To achieve the best results from our solar attic vents, Attic
Breeze recommends inspecting the inside of your attic for uncapped shafts and chases, large
unsealed ceiling seams, or other building features which may allow the air in your home to
freely exchange with the air in your attic. Areas where potential air exchange is identified
should be capped or sealed wherever possible.
SOLAR ATTIC VENTS ARE NOT RECOMMENDED FOR HOMES WITH DROP CEILINGS,
CHASES, OR OTHER BUILDING FEATURES THAT DO NOT PROVIDE AN ADEQUATE
SEAL BETWEEN THE LIVING AND ATTIC SPACES. If you are uncertain if this applies to
your situation, contact us to discuss.
Tip: The better your attic space is sealed preventing air exchange with the inside of your
home (even the small gaps), the more effective your attic insulation will become and the
better the performance you will achieve from your solar attic vent. Since thoroughly
sealing your attic could take some time, Attic Breeze recommends doing so only after
your installation is complete. The temperature inside your attic will be greatly reduced
after installation, making this task much more tolerable.
Step 3 - Location of Your Attic Vent: The proper placement of your solar attic vent will be
based on several factors. For optimum performance, the solar attic vent (or solar panel for
models AB-203D/204D/253D/254D) should be positioned facing either south or southwest.
Additionally, the solar attic vent (or solar panel) should be positioned on an area of your roof
that is not shaded or otherwise blocked from the sun for extended periods throughout the day.
Finally, your attic vent should be positioned on an area of your roof that gives the optimum
distance between the solar attic fan and the air intake vents (soffits or gable vents). The key
to finding the best installation location is in maximizing cross-flow ventilation by balancing the
air intake sources.
IF YOUR HOME IS EQUIPPED WITH TURBINE VENTS, THESE VENTS MAY NEED TO
BE SEALED-OFF OR REMOVED. Your solar attic vent will pull air backwards through the
turbine vent, which may result in poor attic cooling performance if the turbine vent is located in
close proximity to the solar attic vent. In many cases, a turbine vent can be removed and the
solar attic fan installed in its place. If you choose to replace a turbine vent, make sure to
widen the attic hole to the required size (20" diameter) after removing the turbine vent.
Tip: For best results, your attic vent should be installed about two feet below the ridge line of
your roof and as close to the mid-point of your house as possible. In most cases, this
will allow for optimum cooling performance to be achieved from your solar attic vent.
Step 4 - Unpack the Attic Vent: Unpack your new solar attic vent and make sure all listed
parts are included. Be sure to remove all packaging material and tape before proceeding.
Step 5 - Building the Curb Box: Build a 23 ½" x 23 ½"
curb box using a weather treated 2x4 stud (see Fig. 1). The
curb box should easily fit inside the curb-mount flashing of
the attic vent base. Alternatively, a pre-manufactured curb
flashing may be used for your specific roofing application if
available. Contact your local roofing supply store for more
information on pre-manufactured curb flashings that may be
appropriate for your roofing application.
