Step 2 cont.: Check and Prepare Opening.
Check to be sure the framing walls around the
opening are in the same plane. Do this by
performing a "string test" for plumb.
String Test for Plumb: Attach a string diagonally
across the opening from the outside, as shown. The
string(s) should gently touch in the center, if not the
opening is "out of plumb" by twice that distance
and needs to be corrected. Flip the string over itself
to check both planes. Fix any problems now.
*An "out of plumb" condition is one of the most
common reasons door units leak air and water.
Step 3: Caulk the Sub Floor.
On the sub floor at opening, place 3 very large
beads of sealant. Run beads full width of the
opening.
Use Only a high-quality hybrid polymer,
elastomeric or polyurethane sealant;
Therma-Tru recommends OSI QUAD MAX.
Use an Entire Tube when Caulking along the
Sub Floor.
Step 3A: Installation with a Sill Pan.
Place the right and left sill pan ends onto the caulk beads and tightly against
the side of the opening.
Then, liberally coat the overlapped areas and the recessed areas of the pieces
with the PVC cement provided. Place center section(s) in position and hold
pieces together long enough to ensure a good bond.
For added protection, spread a bead of caulk along the glue joints and to help
prevent air infiltration, run a bead of caulk along the lower interior edge of the
sill pan. Additional caulking could affect the performance of the sill pan.
Do Not Caulk the bottom of the Sill when using a sill Pan.
Step 3B: Installation without a Sill Pan.
Note: If a sill extender is used, place a large bead of caulk at the junction of
the extender and the sill approach.
Lay the door unit on edge or face so
that the bottom surface of the sill
can be caulked. Place very large
beads of caulk across the full width
of the sill. Additionally, place beads
of caulk along the junction of the sill
and the jamb and on the bottom
surface of the jambs
brickmould.
Step 3C: Caulking Back side of Brickmould.
Step 4: Place Unit in Opening and Temporarily Fasten.
A counter sink bit will help to conceal the screw heads, if not using provided
hidden fastening system.
Install screws in the center pre-drilled hole locations on both jambs to
temporarily secure the unit in the place. Do not drive screws completely in at
this time. Use #8 X 2-1/2 inch or 3 inch exterior grade screws. If installing
with provided hidden fastening system, install with provided screws.
Do Not Fasten through the Brickmould.
Step 5: Plumb and Fasten Hinge Side Mull Post.
Do not drive the screw completely in at this time.
Note: When installing a French door with active sidelites, first set the hinge
and
mullion for the passive door. For details on properly setting the astragal slide
bolt hole locations, follow the instructions in the astragal site pack.

Important!

Apply sealant to the back side of
brickmould around the entire
perimeter of the door unit.
A 1/2 – 5/8 inch bead of a high-
quality hybrid polymer, elastomeric
or polyurethane sealant is essential.
Therma-Tru recommends
OSI QUAD MAX.
Lift the unit up. With top edge
tilted away from opening, center
the unit and place sill down onto
sill pan or caulk beads and tilt into
opening.
For all door unit configurations,
note the hinge locations and mark
those locations on the jamb faces
near the door surfaces. Pre-drill
1/8 inch diameter holes at these
locations for screw placement.
For Therma-Tru Composite Door
Frame systems, also pre-drill 1/8
inch diameter holes between hinge
locations on both jambs.
Use a 6 foot level and plumb the
hinge side mullion both ways (right
to left and inside to outside).
Pre-drill and insert a screw through
the frame into the header, on each
side of the hinge mull post.
installing with provided hidden
fastening system, install with
provided screws.
Shim directly over hinge side
mull post. Using a 6 foot level,
recheck hinge mull post to ensure
it is plumb and straight. Finish
driving screw tight.
