FOR DOORS USING OPTIONAL SILL PAN GO TO STEP 1I.

E.Apply sill flashing tape #1. Cut a piece of flashing tape 12" longer than the opening width. Apply at the bottom of the opening as shown (IE) so it overhangs 1" to the exterior.

Note: The tape is cut 12" longer than the width so that it will extend 6" up each side of the opening.

F.Tab the sill flashing tape and fold. Cut 1" wide tabs at each corner (1/2" from each side of the corner) (1F). Fold tape to the exterior and press firmly to adhere it to the water resistive barrier.

G.Apply sill flashing tape #2. Cut a piece of flashing tape 12" longer than the opening width. Apply at the bottom, overlapping tape #1 by at least 1". DO NOT allow the tape to extend past the interior face of the framing (1G).

In-swing doors:

If the wall depth is greater than 5", add a third piece of flashing tape. The flashing tape should come to within 1" of the interior face of the framing.

Note: The flashing tape may not fully cover the framing members.

H.Attach the aluminum sill support or wood blocking to the exterior of the box plate to support the edge of the door sill. Place the sill support flush with the subfloor.
