INSTALL DOOR
Warning! To avoid 
injury, use at least 
two people to install. 
Adequately support the 
door until completely 
fastened.
1. Apply a 3/8" bead 
of sealant where 
the back of the trim 
meets the frame. 
Tool into a llet 
shape. Run another 
bead of sealant 
along the back of the 
n/trim where it will 
contact the structure.
2. Tilt the door into the rough opening, making sure the inside of the 
door sill is fully seated into the sealant on the sill pan back dam.
3. Secure the door in the rough opening by pre-drilling holes and then 
driving #8 x 3" drywall/deck screws into the thick part of the jamb 
where shown. Do not fully seat screws.
SHIM PATIO DOOR
Note! Secure all shims 
with sealant.
From the interior, 
shim the head and 
side jambs 6" from 
the corners and at 8" 
intervals. Install shims 
at the strike plate 
and at each hinge 
location so the screws 
(installed later) will 
each penetrate a shim. 
If installing a door 
with a hinge jamb 
in the middle, shim 
underneath the mull 
for support. Shim so the 
door is square, level and plumb. Verify there is a 1/8" margin between 
the frame and the door panels.
SECURE THE DOOR
Note! Vinyl door 
instructions later in 
this section. All others 
begin here. Double 
door units are shown, 
however, the fastening 
instructions also apply 
to triple, quad and 
sidelight French and 
patio door units.
For French Doors:
Remove a screw from 
each hinge next to 
the weatherstrip and 
replace with one of the 
provided #8 x 3" screws, 
seating all screws fully.

For Patio Doors:
Pre-drill and install 
four more #8 x 3" 
screws through the 
thick part of the jamb 
where shown in a 
similar manner to those 
installed previously. 
Seat all screws fully.
VINYL FRENCH AND PATIO DOORS:
Note! Use the six screws that come in the hardware pack to install the 
door. The hardware pack also contains six screw caps and a #25 torx bit 
to install the screws.
1. Verify the door 
is level, square 
and plumb. Check 
for even margins 
around all panels 
and the frame and 
that the lockset 
holes (if applicable) 
align properly. If 
not, adjust shims. 
Once the screws are 
captured in the jamb 
jacks, they cannot 
be removed and 
reinstalled.
2. Use the jamb jack 
screws and TORX bit 
(provided) to initially 
secure the frame 
to the opening at 
locations 1 & 2. Turn 
jamb jack screws #1 
& #2 until they click 
twice. Do the same 
for #3.
3. Check the inside of 
jamb on the #1 side 
for plumb and adjust 
by turning jamb jack 
screws clockwise to 
move toward the jamb, or counter clockwise to move away from the 
jamb. Check unit for plumb, square and level.
4. Turn #4 jamb jack screw until it clicks twice. Adjust jamb jack screws 
on the #4 side to plumb jamb. Again, check unit for level, plumb and 
square.
5. Tighten jamb jack screws #5 and # 6 being careful not to bow the side 
jambs.
6. Check unit for plumb, square and level and adjust as necessary.
