What’s Needed
 cordless drill with nut driver attachments
 tape measure
 hammer
 scissors
 reciprocating saw
 roofing-grade weatherproof sealant
The location where you wish to install the roof curb should be clear of roofing
materials (tile roofs) with a square vent hole measuring 20” x 20” cut into the
roof decking. Please refer to the installation instructions included with your
Attic Breeze curb mounted fan for details.
The roof curb will need to be mounted flush to either the framing structure
or decking of your roof. Position your Attic Breeze roof curb over the vent
hole and use it as a template to mark off the area where the roof curb will
be mounted. For tile roof installations, use a hammer to remove any
battens under the roof curb area as needed (see Figure 1) so that the roof
curb can be mounted flush to the decking. For metal roof installations, use
a reciprocating saw to notch the standing seam back under the marked
area to allow the roof curb to mount flush with the metal decking.

Figure 1 - Remove Battens
Figure 2 - Apply Sealant
Using a roofing-grade weatherproof sealant, apply sealant around the bottom
side of the roof curb as shown in Figure 2. Position the roof curb over the
vent hole, squaring the curb with your roof tiles or standing seams. Using
the included self-tapping screws, securely fasten the roof curb in place to
the framing members, decking, or metal roof sheeting by applying two
screws to each side of the roof curb’s flashing. For tile roof installations,
apply sealant to mounting screws and around the roof curb base. Replace
roof tiles as needed up to the installed roof curb.
