WARNING! To avoid injury, use at least two people to install.
Adequately support the window until completely fastened.
Areas such as Florida and the Texas TDI region have different
anchoring requirements based on product certification. For
information on specific products, visit www.floridabuilding.org
or www.tdi.texas.gov and follow the anchoring schedule given in
the drawings for the product instead of the anchoring schedule in
thisdocument.
Note! Fastener (anchor) heads must be flush. Do not dent nailing fin.
1. Run a continuous 3/8" bead of sealant around the interior side of the
nail fin/trim on the side jambs and head. On the sill, leave at least a 2"
gap every 8" where it will contact the rough opening (Fig. A).
2. Place window onto the shimming support and tilt into the rough
opening. The window sill must rest on and be fully supported by the
shimmingsupport.
3. Fasten window through the nailing n/trim between 3"-7" from one
uppercorner (Fig. B).

4. Shim at each interlock, or in the center, and within 4"-6" of each
corner on the side and head jambs. Apply additional shims to the
side and head jambs as necessary to ensure window position within
the opening is plumb, level and square. Larger windows usually need
additional shims. Shims can be secured with sealant oradhesive.
5. Inspect window for square, level and plumb. Test for proper operation
(remove and reinstall if necessary).
