of the sill. Apply more
sealant as necessary.

INSTALL DRIP CAP
A drip cap is not provided with this door unit; however, the use of a drip
cap is strongly recommended and may be required by local code.
1. Cut a piece of drip cap the length of the header brickmould plus
1/4" to allow for 1/8" overlap past the ends of the door frame or
exterior trim.

CREATE “INTERIOR” AIR SEAL
Continuous Air Seal
NOTE: Shims may need to be cut back, so the interior air seal is
“continuous” between the patio door frame and the rough opening.
Create a required continuous air seal on the interior by integrating the
rough opening and the patio door frame with low-expansion polyurethane
foam or backer rod and sealant. NOTE: If foam is used, a 1/2" - 1" depth
is prescribed. Backer rod can be used to control the depth.
Finishing Sidelite or Transom Installations
1. If installing a door with a sidelite(s), shim the head on both sides of
the joint where the sidelite joins the door jamb. Fasten next to the
shims and then remove shims.
2. Shim the head of units with sidelite(s) at the center of each slab/
sidelite. Fasten next to the shims and then remove shims. Similarly
fasten a transom every 16".
2. Apply a 1/4" bead of sealant to the top of the door frame or exterior
trim along the front and side edges.
3. Nail the drip cap into place and apply sealant to the edges on
the side.
