2 OPENING PREPARATION
A. Prepare the door opening by removing the venting panel and the glass from the existing fixed side of the aluminum door frame.
Note: It may be necessary to cut the divider |
|
between the venting panel and fixed glass areas |
|
with a reciprocating saw. The existing aluminum |
|
frame is left in place so as not to disturb the existing | 2B |
exterior stucco flashing or drainage system. |
B. Cut the existing door sill out of the opening. Using a reciprocating saw or side grinder, cut the existing sill as close to the longest leg of the jamb extrusion as possible.

Note: Be careful to avoid damage to the interior flooring materials. Drilling holes in the sill prior to cutting may make the removal of the existing sill easier. If existing sill has a stainless steel cap on the sill, removing the cap prior to cutting will make cutting easier.
C.Clean old sealant and other debris from the door opening.

D.Remove the door lock strike from the lock jamb of the existing door frame.
E.Place a bead of sealant at each joint where the existing door frame jambs meet the existing door sill pieces. Fill any holes in the jamb and head with sealant.
F.If the weep holes of the existing sill have been cut away, drill new weep holes in the existing door jambs. Be sure to drill weep holes in all vertical jamb legs, except the most interior leg.
Note: Ensure all new or existing weep holes are open before proceeding with the installation.
G.Cut wood blocking to fill the vent and fixed panel cavities in the head and jamb of the existing door frame. The depth of the blocking should be the same height as the tallest leg of the existing jamb extrusion. Cut the head blocking to fill the entire length of the head in both channels. Cut the jamb blocking to fill both jamb channels to within approximately 1" of the bottom of the jamb.

H.Set the wood blocking in sealant in the existing door frame. Make sure the blocking is flush with the furthest protruding part of the existing jamb. Place a 3/16" bead of sealant in the door panel cavities, then insert the wood blocking into the head cavities followed by the jamb cavities. Next insert the wood blocking into the jamb panel cavities of the existing door frame. Secure the blocking by
