Installation Guide

STEP 7: Shim and Fasten Unit
NOTE: Units intended for
installation in high velocity
windstorm regions may require
additional points of attachment.
NOTE: Install shims in the
correct location and in
the proper sequence.
Shim tightly at the bottom of
the unit at points indicated.
Shim the top side of the frame as
indicated. Install shims until there
is a 1/8" gap between the top of the
door and the frame header. There
should also be a consistent gap
(1/8") between
the door and the vertical astragal
(for French Door Units).
STEP 8:
For French Units Only
NOTE: Most units do not have pre-drilled holes for
the top and bottom flush bolts on the inactive door.
Close door firmly against frame weatherstrip.
Slide top and bottom flush bolts up against
header and sill. Mark where bolts make
contact with the header and sill.
Drill 3/8”diameter holes on the marks to
receive bolts. (1-1/2” deep minimum) .
STEP 9: Insulate and
Install Hardware
Score shims with razor knife and snap
flush with frame face. Insulate any gaps
between the frame and rough opening
with fiberglass blanket insulation. (Do
not use spray-in foam.) Install interior/
exterior trim around frame unit. Install
hardware according to the manufacturer’s
instructions. Use long security screws
to attach deadbolt strike plate.
STEP 10: Caulk Doorway
Caulk all exterior corners and all around the brick or siding.
Caulk the sill on both latch and hinge sides from the edge of the sill crown
along the edge where the sill and jamb or brickmold meet.
Caulk the front sill edge where the sill and the sub-floor meet.
Caulk the top corners where the header and jambs meet, starting at the
weatherstrip and working to the face of the brickmold.
Caulk the perimeter where the exterior trim meets the brick or siding trim.
If the door is center-hinged or has a sidelite, caulk around the mullions
where the mullions contact the sill and header.
STEP 2: Determine Rough Opening & Door Frame Size
■
R.O.= Rough Opening
■
Rough opening width is measured from the inside of the
stud frame to the inside of the opposite stud.
■
Rough opening height is measured from the sub-floor to the bottom of the header.
■
Rough opening allows for room to shim on each side of unit.
■
To measure the rough opening for a unit that is being replaced, remove interior casing and
measure from stud to stud and from floor to header.
NOTE: It is easier to reduce the R.O. size by shimming or adding
wall studs than it is to enlarge a R.O.
■
2" x 4" or 2" x 6" construction simply refers to the width of
lumber used to frame the rough opening.
■
Jamb is wider than framing lumber to allow the jamb to
overlap the wallboard, panelling, siding etc.
■
Brickmould covers the gap between the rough opening and the door jamb
on the exterior wall and door casing should be applied on the interior
STEP 3: Prepare Rough Opening
A solid level sub-floor is absolutely
essential for proper door unit
installation. Do not proceed until the
sub-floor is both solid and level.
Clean and clear work area.
NOTE: Apply flashing in a manner to
prevent entry of water into the wall
cavity in accordance with flashing
manufacturer’s instructions
STEP 4: Prepare Door Unit.
Remove all packaging from door unit. Some units may have a wood screw attached
through the top of the header and into the top of the inactive door of a French unit. Remove
this screw. Be careful when handling unit to prevent doors from swinging open.
STEP 5:
Caulk Sub-Floor and Sill
Variations in threshold designs may require that the caulk lines be applied directly to the
bottom of the unit to ensure a weather-seal. Inspect the bottom of the sill for any flat
surfaces or sill grooves. Apply caulk to sill bottom flat surfaces and grooves and also bottom
of jambs. Apply a triple bead of caulk along sub-floor where unit will be positioned.
STEP 6:
Place Unit in Rough Opening
Do not attempt to handle without
assistance. From the outside of the
unit, center the prehung unit into the
rough opening, sill first. Be careful
not to disturb the caulking on the sub-
floor or sill bottom. The brickmold (not
supplied with all units) should rest up
against the exterior finished wall.

IMPORTANT:
Read and understand the entire procedure before attempting to install
the unit. Please note that this is a supplemental instruction. Installation
instructions will also be attached to the purchased unit.
NOTE:
Some dwelling designs/conditions may require special installation steps. Consult an
architect, design professional and/or code official for additional guidance. If disturbing
existing paint, take proper precautions if lead paint is suspected (commonly used
before 1979). For proper management of lead paint, see www.epa.gov/lead
CAUTION:
Wear safety glasses and gloves when installing the patio unit. Unit will
be heavy. At least two people are needed for installation.
