PREPARE DOOR
1.  On the interior 
side, apply a 
continuous bead 
of silicone sealant 
where the exterior 
trim meets the 
door frame as 
shown. Tool into a 
llet shape.

the sill pan back 
dam and over the 
ashing joints as 
shown.
INSTALL DOOR
WARNING! If installing fasteners through berglass components, we 
recommend pre-drilling holes to keep the berglass from splitting.
Note! This section covers single door installations. If installing a door 
unit with a transom or a sidelight(s), there will be additional steps. For 
double door units, follow the instructions accordingly as they apply 
to hinge or latch jambs and complete the steps under “ALTERNATE 
CONFIGURATIONS” later in this section as they apply.
1.  Remove any pre-hanging clips that are fastened to the outside of 
the jamb that will be covered when the unit is placed in the rough 
opening. Adequately support the slab to keep it from swinging 
open during installation.
2. Applya3/8"bead
of sealant to the 
back of the trim 
where it will contact 
the structure. From 
the outside, tilt the 
entire pre-hung 
door into the center 
of the opening. 
Make sure the sill 
contacts the sealant 
on the sill pan back 
dam.
3. Temporarilyfasten
the hinge jamb by 
placing one 10d 
nish nail (or one 
#8x3"drywall
screw)horizontally
centered in the 
hinge jamb or 
brickmould trim 16" 
from the top and 
bottom of the door. 
Do not set nails/
screws.
4. Fromtheinside,
shim the hinge 
jamb at each hinge 
location until the 
door is square in the 
opening.
5. Fromtheinside,
shim the latch jamb 
by placing one shim 
at the strike plate 
and one across from 
the top and bottom 
hinges. Verify the door is square.

freely and that the space between the door and the jamb is even on 
all sides. Adjust if necessary.
