4. Take this distance

from the back edge

folding line across
the sheet material.

landings, cut 1/2" in
at this line on both
sides of the sheet
material.

6. For continuous

slab, cut across the
folding line.

7. Fold the three back

sides up to make a
3-sided box, and, for
step-down landings,
fold the front flap
down.

1. Set the sill pan

in the rough
opening, aligning
the front edge (for
continuous slab) or
folded down edge
(for step down)
with the exterior of
the rough opening.

PREPARE BUCK

Note!

This section applies to installations into a buck only. For

installations into a stud-framed wall, begin with section 5, “PREPARE
STUD-FRAMED WALL.”
1. Seal any joint larger than 1/16" in the buck and between the buck

and the concrete/masonry with sealant.

2. Cover the buck and the surrounding concrete/masonry at the head

and jambs and sill with liquid applied flashing as shown.

END of Buck Instructions, SKIP to section 6, “INSTALL DOOR.”

PREPARE STUD - FRAMED WALL

FOR RETROFIT INSTALLATIONS

Completely remove the old door unit. Verify rough opening is structurally
sound and header is able to carry the combined weight of all the panels.

PREPARE BUILDING WRAP

Verify these steps are allowed by the building wrap manufacturer.
1. Trim building wrap flush with the edges of the rough opening.
2. If installing a drip

cap, (recommended
because this
integrates the
building wrap and
drip cap to protect
the structure and
the product from
incidental water)
at the head, slit
building wrap 6"
at 45°. Tape up as
shown.

3. Trim the sides

sufficiently to allow
the nailing fin to be
mounted against the
sheathing.

3. Apply spray adhesive/

primer to the sill pan
and surrounding
area. Follow
manufacturer’s
instructions for
application methods.

4. Cut a piece of self-

adhesive flashing the
length of the sill and
apply over the sill pan as shown. The bottom of the sill pan should
be completely covered by the self-adhesive flashing. For step down
landings, fold flashing down as shown. For continuous slabs, trim
flush with rough opening.
