The sill can be prepared using one of two methods: We recommend
SureSill
™
Sloped Sill Pan
™
available from SureSill at www.suresill.com,
building supply stores, and some manufacturing locations or fabricate a
sill pan on site. If installing a SureSill
™
sill pan, follow SureSill’s instructions
for installation and skip to section 4 “PREPARE BUCK“, or to section
5, “PREPARE STUD-FRAMED WALL“ as it applies to your situation. If
fabricating a sill pan on the job site, follow the instructions below.
JOBSITE FABRICATED SILL PAN
1. Cut a piece of sheet
material to the
length shown.
2. Lightly crease folding
lines 1/2" in from the
two short sides and
one long side.
3. Measure the width
of the frame and
add9/16".
4. Take this distance
from the back edge
and lightly crease a
folding line across
the sheet material.
5. For step-down
landings, cut 1/2"
in at this line on
both sides of the
sheetmaterial.
• Verify the width and height
of the door frame are each
1/2"- 3/4" smaller than the
rough opening width/height.
• Verify the rough opening
is square. The (A) and (B)
measurements should be the
same. Maximum allowable
deviation from square is 1/4".
• Verify the rough opening is
plumb and level (C, E) and
(D). The maximum allowable
deviation is 1/16" for every
2' of rough opening (not to
exceed 1/8").

REMOVE PACKAGING
Remove shipping materials such as corner covers, shipping blocks
or pads.
INSPECT DOOR
• Cosmetic damage
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
ap down.
INSTALL SILL PAN
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.
2. Mark a line across the
front and back of the
sillpan.
3. Apply three 3/8" beads of
sealant between the lines.
4. Place the sill pan in the
rough opening. Firmly
press the sill pan into the
sealant with a J-roller.
Sealant
• Correct product (size, color, grid pattern, handing, glazing, energy-
efciency requirements, etc.)
If any of the above conditions represent a concern, or if you expect
environmental conditions to exceed the door's performance rating,
do not install the door. Contact your dealer or distributor for
recommendations.
• The rough opening sill must not be crowned or sagged (D), but rather
level or sloped (positive slope) to the exterior.
• The exterior face of the rough opening must be in a single plane (E)
with less than 1/8" twist from corner to corner.
• In wood frame construction, the header must be supported by
trimmer studs and designed to ensure that no load is transferred to
patio door unit.
• Correct any deviations before installing the patio door. Consult a
building professional as needed.
• Verify the rough opening is clean and dry.
FOR RETROFIT INSTALLATIONS
After removing the old door, remove sufcient cladding (siding, stucco,
etc.) to expose enough intact building wrap to properly seal the door
system to the opening. If damaged, apply new building wrap in shiplap
manner. Verify the rough opening framing is structurally sound. Contact
your local waste management entities for proper disposal or recycling
of products being removed.
