Instructions / Assembly
8  Once the window is plumb, level and square, install 
installation screws into the  prefabricated installation 
holes in the jambs. Shims should be used to establish 
spacing at anchoring points and should be penetrated 
by the installation screw. DO NOT OVER TIGHTEN 
THE SCREWS, as this could cause the frame to bow. 
Recheck the sash for proper operation once the 
screws have been installed. Caulk and cover the instal-
lation holes when necessary. If the windows do not 
have prefabricated holes, pre-drilling and countersink-
ing the screws will be required. Cover the hole with the 
appropriate sized plug button. Buttons can be 
obtained from your dealer or supplier.
Note: When installing Casements, place screws in the 
installation holes. Prior to placing the #10 x 2 ½" screw in 
the sill, drill two holes in the uppermost level of the sill with 
a stepdrill. Holes should be 3 from each interior corner and 
½" from the innermost surface of the frame tower. The drill 
bit should be ³⁄16 in diameter, with the step being ³⁄8 in 
diameter. Drill straight down (Fig. D) until the step just 
breaks the first layer of the vinyl. A separate layer of vinyl 
should be visible which is where the head of the screw will 
rest. Install the screws into the holes so that the head of 
the screw rests on the inner chamber. Seal the head of the 
screw with an approved sealant and cap the hole with a 
plug button to be sure the holes remain watertight. 
Replace a screw in each tie bar guide with installation 
screws (Fig. E). After the window is secured, recheck the 
sash operation and the weather seals. With Awning win-
dows, install installation screws in the head and sill as 
described in the Casement procedures (Fig. D). Replace 
one of the center screws in the operator assembly with an 
installation screw (Fig. F). 
Replace the second screw from the top and the closest 
screw to the bottom on the hinge tracks with installation 
screws (Fig. G). After the window is secure, recheck the 
sash operation and weather seals.
9   If installing large windows or win dows with high wind 
load requirements, install interior and exterior blind 
stops along the jambs, head and sill (if not already 
present). The blind stops must be a minimum of ¾  
by ½.
10  If installing a window with a stucco flange, follow the 
preceding instructions. Before placing the window into 
the opening for the final time after making sure it will 
be plumb, level and square, place a heavy layer of 
caulking along the interior of stucco flange approxi-
mately ½" from the bottom edge. Leave two small 
gaps in the caulking at either end of the bottom edge 
of the stucco flange.
11  Finish off the exterior of the window. Seal the entire 
perimeter of the window with the proper grade of seal-
ant. Trim and cap off where necessary. Do not cover 
weeps. Use of expanding foam is acceptable as long 
as it meets AAMA 812 specifications.
12  Make certain sash open, close and lock properly. 
Operable slider sash should lift out freely. Finish off  
the interior of the window.
13 Remember: The homeowner is the final inspector. 
Clean the window well and remove all debris from the 
job site. Be sure the homeowner is familiar with the 
proper operation and all the features of the window. 
Make sure you have supplied the homeowner with  
the proper warranty card, as this will explain proper 
cleaning and operating function of the window.
