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.
