with the exterior of
the rough opening.
2. Mark a line across
the front and back
of the sill pan.

3. Cut a piece of self-
adhesive ashing
the length of the sill
and apply over the
entire sill pan. For
step down landings,
fold ashing down
as shown. For
continuous slabs,
trim ush with
rough opening.
4. Cut two pieces
of self-adhesive
ashing 6" wide by
the sill pan width +
3" long.
a. For continuous
slab landings
only, cut out the
inside corner.
b. Adhere the
pieces of
ashing to the
inside corners.
Stretch ashing
as needed to
cover corners
and lay at.
5. Smooth gaps or
bubbles beneath
self-adhesive
ashing with a
J-roller (remove
and replace if
necessary).
6. Seal back corners of
sill pan with sealant.
7. For step-down
landings only, cut
plastic drain screen
to length of sill
+ 2", center, and
staple 1/2" below sill edge.
FOR RETROFIT INSTALLATIONS
Remove the old patio door. Add at least 2" to the width of the ashing
and use that measurement to remove trim/siding and expose intact
building wrap. If damaged, apply new building wrap in a shiplap
manner. Verify trimmer studs and header are structurally sound.
Continue with the instructions.
PREPARE BUILDING WRAP
Verify these steps are
allowed by the building
wrap manufacturer.
Note! Steps 1 and 2
apply only to new
construction.
1. Trim building wrap
ush with the
edges of the rough
opening.
2. Slit building wrap
corners 45° as
shown and high
enough to allow
ashing to adhere to sheathing (usually at least 1"higher than the
width of the ashing). Tape up as shown.
INSTALL JOBSITE FABRICATED SILL PAN
Note! The rest of the steps in this section only apply to a job site
fabricated sill pan. If installing a sill pan that you have purchased,
follow manufacturer's instructions for installation and skip to section 5,
“INSTALL PATIO DOOR.”
1. If installing a metal
sill pan on concrete,
cut a piece of self-
adhesive ashing
the length of the
sill pan and adhere
it to the entire
bottom surface
where the pan will
sit on the concrete.
2. If fasteners are
required through
the sill, apply
spray adhesive/
primer to the sill pan and surrounding area. Follow spray adhesive
manufacturers' instructions for application methods.
