ASSEMBLY AND INSTALLATION INSTRUCTIONS
for Premium Aluminum (A-500) and Premium Atlantic Aluminum Sliding Patio Doors (JII020)
5
PREPARE BUILDING WRAP
(For masonry/block wall
construction, skip to SILL
PANS)
Trim building wrap flush
with the edge of the
rough opening at the
head and sides.
SILL PANS
(For a recessed sill pocket, skip to COMPLETE OPENING PREP)
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 5 “INSTALL FRAME“. If
fabricating a sill pan on the job site, follow the instructions below.
JOBSITE FABRICATED SILL PAN
(For a recessed
sill pocket, skip
to COMPLETE
OPENING PREP)
Note!
If using self-
adhesive flashing in
place of a metal pan,
the flashing must be a
minimum of 40 mils and
have a proper back dam,
such as a metal angle.
Use primer if adhering
to concrete.
• Cut a piece of sheet
material to the length
shown.
• Lightly crease folding
lines 1/2" in from the
two short sides and
one long side.
• Measure the width
of the exterior edge
of the frame and add
9/16".
• Take this distance from
the back edge of the
sheet material and
lightly crease a folding
line.
• Cut 1/2" in at this line
on both sides of the
sheet material.
• Fold the three back
sides up to make a
3-sided box.
• For step-down
landings, fold the
front flap down. For
continuous slabs, remove the front flap.
INSTALL SILL PAN
Note!
If installing
a metal sill pan on
concrete, the bottom
surface must be covered
with self-adhesive
flashing.
• Set the sill pan in place
pressing it down firmly
into the sealant. Use
a J-roller if necessary
to ensure a smooth,
secure seal.
• Apply a 3/8"
continuous bead of
sealant across the sill
pan back dam.
• For step-down landing
apply a layer of liquid
flashing across the
lower lip of the sill
pan, joining it to the
face of the foundation.
