Installation Instructions
for Pre-Hung Exterior Entry Doors (JII106)
INSTALL SILL PAN
Landings
These instructions cover two sill conditions: the step-down landing
and the continuous slab landing. The installation methods vary slightly
between landing types.
Step-Down Landing
Prepare Sill
1. A pan ashing system (as
dened in ASTM E2112) is
required at the sill prior to
window/door installation.
Always allow water to drain
out of the pan and onto the
building wrap, drainage plane
or to the exterior. NOTE: Sill
pans for step-down landings
will have a folded-down edge
in the front to accept the step-
down landing.
Continuous Slab Landing
2. Apply a continuous
bead of sealant to the
interior upturned leg
and end dams of the
sill pan (if using a rigid
sill pan).
NOTE: For doors with an ADA sill, liquid applied membrane or threshold
tape can be applied to the rough threshold/sill prior to the installation of
the door. Dry t the door frame to dene ashing locations.
Shim the Sill
See Product Installation Tolerance Table for tolerances
1. Unless installing into a
sill pan with a positive
sloped draining system,
shims should be aligned
as dened by the label
on the door or as
statedbelow:
• Shims (1/4"
maximum) in height.
• Place one shim 2"
from each side of the
rough opening.
2"
8" O.C.
• Shims should be no more than 8" on-center.
• There should always be a drainage path to the exterior out of the
sill pan.
• Shims can be held in place with sealant.
• Increased shim height may be needed or may interfere with bar/
grill alignment of adjacent windows/doors.
NOTE: The steps above exclude doors with an ADA sill.
