Installation Instructions for Typical Wood Frame Construction.
These instructions were developed and tested for use with typical wood frame wall construction
in a wall system designed to manage water. These instructions are not to be used with any
other construction method. Installation instructions for use with other construction methods,
multiple units or bow and bay windows, may be obtained from Pella Corporation, a local Pella
retailer, or by visiting http://www.pella.com. Building designs, construction methods, building
materials, and site conditions unique to your project may require an installation method
different from these instructions and additional care. Determining the appropriate installation
method is the responsibility of you, your architect, or construction professional.

REMEMBER TO USE APPROPRIATE PERSONAL PROTECTIVE EQUIPMENT.
A. Verify the opening is plumb and level.
Note: It is critical that the bottom is level.
B. Verify the window will fit the opening.
Measure all four sides of the opening to make
sure it is 3/4" larger than the window in
both width and height. On larger openings
measure the width and height in several
places to ensure the header or studs are not
bowed.
Note: 1-1/2" or more of solid wood blocking
is required around the perimeter of the
opening. Fix any problems with the rough
opening before proceeding.

E. Apply sill flashing tape #1. Cut a piece of flashing tape 12"
longer than the opening width. Apply at the bottom of the
opening as shown (1E) so it overhangs 1" to the exterior.
Note: The tape is cut 12" longer than the width so that it
will extend 6" up each side of the opening.
F. Tab the sill flashing tape and fold. Cut 1" wide tabs at each
corner (1/2" from each side of corner) (1F). Fold tape to the
exterior and press firmly to adhere it to the water resistive
barrier.
G. Apply sill flashing tape #2. Cut a piece of flashing tape
12" longer than the opening width. Apply at the bottom,
overlapping tape #1 by at least 1". Do not allow the tape to
extend past the interior face of the framing (1G).
Note: The flashing tape may not fully cover the framing
members.

A. Install and level sill spacers. Place 1" wide by 3/8" thick spacers
on the bottom of the window opening 1/2" from each side.
Spacers are also required at points where windows are joined in
multiple window applications. Add shims as necessary to ensure
the spacers are level. Once level, attach spacers and shims to
prevent movement.
Note: Improper placement of shims or spacers may result in
bowing the bottom of the window.

2C
B. Remove plastic wrap and cardboard packaging from window. DO NOT remove plastic
shipping spacers located between the window sash and frame. The shipping spacers will
help keep the window square during installation. DO NOT unlock or open the window
until it is fully fastened.
Note: If screens, grilles or hardware are removed from the window at this time, label
them and store them in a protected area.
C. Fold out installation fin to 90°. Be careful not to remove or
tear the fin corners.
Note: If the fin is not at 90°, the window will not line up
correctly on the interior.

Extruded Fin
D. Curved Units with Fins:
Curved Units with frame radius > 12" will be provided with fixed fin.
On windows with fixed extruded fin, drill 1/8" diameter holes in the fin every 12".

F. Plumb and square window. Place shims 1" from
the bottom and top of the window between the
window and the sides of the opening. Adjust
the shims as required to plumb and square the
window in the opening. If the frame height
exceeds 53", place shims at the midpoint of the
window sides.
Note: Do not shim above the window or in the
space between the spacers at the bottom of the
window. DO NOT over shim.
D. Curved Units with Fins (Continued):
Curved Units with frame radius ≤ 12", full circle
and elipse units will be provided with a flexible
non-structural fin on the curved portion of the
unit.
Note: This fin is intended for flashing only, not as
structural support.
Installation Clips for Structural Support:
Determine installation clip placement. Clips
(provided) should be evenly spaced across the curved
frame member and no more than 16" on center.
Place the clips so the lip is facing up and against the
instillation fin. Secure each clip by driving a #6 x 5/8"
corrosion resistant screws through the outer two holes
of the three holes shown.
2E
E. Insert the window from the exterior of the building. Place
the bottom of the window on the spacers at the bottom of the
opening, then tilt the top into position. Center the window
between the sides of the opening to allow clearance for
shimming, and insert one roofing nail in the first hole from
the corner on each end of the top nailing fin. These are used
to hold the window in place while shimming it plumb and
square.
TWO OR MORE PEOPLE WILL BE REQUIRED FOR THE

Note: The flashing tape must be applied approximately 1/2"
onto the frame cladding at the jambs and head. Pre-folding
the tape at 1/2" before removing the paper backing will make
it easier to apply the tape correctly. If the siding is less than
1/2" thick, adjust the dimension of the fold so the exterior
sealant line will cover the exterior edge of the tape.
G. Check the interior reveal. Make sure the measurement from the interior
face of the window to the interior face of the wall is equal at several
points around the window.
Note: If the dimensions are not equal, check to make sure the fins are
folded out to 90° at all points.
H. Check window operation (vent units only). Unlock the window by
lifting the lock handle up. Open the window by rotating the crank
handle. Remove the shipping spacers. Open and close the window a few
times to check for proper operation. Close and lock the window.
Note: If there are any problems with the operation of the window,
recheck shim locations and adjust for plumb and square.
I. Fasten the window to opening by driving 2" galvanized roofing
nails into each pre-punched hole in the nailing fin.
Note: Make sure the fin corner is lying as flat as possible.

3INTEGRATING THE WINDOW TO THE
WATER RESISTIVE bARRIER
J. For units with flexible non-structural curved fin on which
clips were added: Fasten the clips to the opening by driving
two #6 x 1-1/2" or longer corrosion resistant into the pre-
punched holes in the clips. If clips are bent and fastened to the
interior stud, install the screws as close to the bend as possible.
Note: DO NOT shim above the window. 2J
Flashing
Tape
Rectangular Units Only:
A. Apply side flashing tape. Cut two pieces of flashing tape
4" longer than the frame height of the window. Apply
one piece to each side 1/2" onto the frame cladding, over
the nailing fin and onto the water resistive barrier. The
tape should extend 2" above the top of the window and
2" below the bottom of the window. Press the tape down
firmly while folding down the excess tape at the top and
bottom of the window.
B. Apply top flashing tape. Cut a piece of flashing tape
long enough to go across the top of the window and
extend at least 1" past the side flashing tape on both
sides. Apply the tape 1/2" onto the frame cladding, over
the top nailing fin as shown. Fold the overlapping tape
down, and press all tape down firmly.
Note: DO NOT tape or seal the bottom nailing fin.
