board piece

lengthwise into

“L” shape. Center

leg to head

board and the

the header piece

above the header.

adhesive flashing

for gaps or

bubbles (remove

and replace if

necessary).

1. If the window has

a pre-installed

cable support

system, follow

the instructions

provided by the

manufacturer.

2. If the cable

support system

is not used,

build seat board

bracing to

support at least

750 lbs of total

weight (window

plus window

contents). Primary

support should be

provided under

the mull joints of

the unit.

3. Remove temporary support after full support is installed.
4. Release the building wrap from above the header (previously taped

up) and overlap the header flashing. Seal the ends with self-adhesive

flashing or building wrap tape.

5. Seal all four corners of the window with a 1/4" bead of sealant. Tool

into a fillet shape.

6. The head and seat boards should be protected and insulated with a

structure designed and built as required by local code.

7. Create a continuous

air seal on the

interior jambs and

head between the

rough opening and

the window frame

with low expansion

polyurethane foam

or backer rod and

sealant. On the sill,

run a continuous

bead of sealant

along the foam

wedge where it

meets the window

frame or seat board.

AFTER INSTALLATION

1. Adjust window for best operation.
2. Install exterior wall surface within 30 days of window installation.
3. Maintain gap of 3/8" between window frame and final exterior wall

surface (siding, stucco, etc.).

4. Protect recently installed units from damage from plaster, paint, etc.

by covering the unit with plastic.
