Pre-Hung Unit Installation

Step 5: Shim at Hinge Locations and Secure Hinge jamb.

Leave door fastened and closed with transport clip.

Shim above screws, behind each hinge location,

between the opening and the jamb.

Use a 6 foot level and re-check hinge jamb to ensure it

is plumb and straight.

Finish driving screws tight in the middle first then top

and bottom last.



Step 6: Adjust Rest of Frame and Fasten.

From the weatherstrip side of the door, check

weatherstrip margins and contact.

Make frame adjustments so the weatherstrip

contacts the door surface equally at the top,

middle and bottom, an even 3/8 inch to 1/2

inch when fully closed.

Secure the lock side jamb with #8 X 2-1/2 or 3 inch screws through the pre-

drilled holes at the top and bottom. Do Not drive screws tight at this time.

From the swing side of the door, shim above the screw locations and make

adjustments so the margins between the door and frame are even top to

bottom.

Note: For Double Doors, make adjustments that effect the alignment, margins

and weatherstrip contact between the doors. Also follow the Astragal Site

Package Instructions for details on properly setting the slide bolt hole

locations.

Step 6 cont: Adjust Rest of Frame and Fasten.

Re-check everywhere for plumb and square, and an

even weatherstrip contact.

Finish driving all screws tight.




Step 7: Remove Transport Clip and Open Door.

Remove the transport clip.

Open and close door to check for smooth

operation.


With the door open, drill 1/8 inch diameter pilot

holes in the top hinge in the 2 screw hole

locations closest to the weatherstrip. Then, install

the #10 X 2-1/2 inch screws (provided) through

the hinge, into the stud, to anchor the door frame

and prevent sagging.

Step 7 cont.: Remove Transport Clip and Open Door.

For Sidelite and Patio Units: With the door open, check to determine if the 2-

1/2 inch long hinge screws were pre-installed in the hinges. If not, drill 1/8

inch diameter pilot holes and install the long hinge screws in the hole

locations closest to the weatherstrip.

Close the door and carefully shim between the jamb and the opening behind

the adjustable strike plate area.

Then open the door and drill 1/8 inch dia. pilot

holes and install the #8 X 2-1/2 inch screws

(provided) through the strike plate holes to

secure the lock side jamb and provide security.

Adjust strike plate in or out for proper

weatherstrip contact and door operation, then

finish tightening screws.

Step 8: Adjust Sill.

Your door unit may have an adjustable threshold cap. When properly

adjusted, it should be snug and slightly difficult to pull a dollar bill out from

under the door when it is fully closed. The dollar bill should be able to be

removed without tearing.


This check should be performed at each

adjustment screw location.



After adjusting the threshold cap, ensure that the

weatherstrip is flush with the top of the threshold

cap. Trim as necessary.


Step 9: Install Corner Seal Pads – Inswing units Only.

Apply sealant (Polyurethane or

Elastomeric) at the joint where the

threshold cap meets the door jambs.

Remove the self-stick paper from

the corner seal pads and apply to the

door jamb, with the bottom lined up

evenly with the top of the threshold

cap. When the pad is correctly

installed, the tab is on top and the

narrow part is on the bottom.

The bottom of the pad is the same width of the threshold cap to help with

alignment during installation.

Step 10: Additional Frame Anchoring.

If sill is prepared for anchoring screws, place appropriate screws through

the sill into the sub floor where needed. (Primarily on Outswing Sills)

We recommend that you provide additional frame anchoring as shown

here. Certain states or jurisdictions, notably Florida and the coast of

Texas, have specific installation requirements and may require

installation in strict accordance with the product approval for a specific

product. You should always check with the local authority having

jurisdiction for any specific installation requirements that may apply.

Specific product approval installation instructions, including those

required for the High Velocity Zone (HVHZ), are also available at
