FOR RETROFIT INSTALLATIONS
Remove the old patio door. If installing into stud framing, remove
sufficient siding to expose at least 9" of intact building wrap. If
damaged, apply new building wrap in a shiplap manner. Verify header
and trimmer studs are structurally sound. If installing into a block wall,
removing the stucco is not necessary if the existing rough opening
is waterproof and the patio door is downsized. Continue with the
instructions.
PREPARE BUILDING WRAP
Cut flush with the
edges of the rough
opening, or follow
building wrap
manufacturer’s
instructions for proper
methods of preparing
the weather barrier.
PREPARE SILL

the rough opening,
aligning the front
edge (for continuous
slab, shown) 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 and
remove.
3. Apply three 3/8"
beads of sealant
between the marked
lines.
