Seal the joints [A] on the exterior between the vertical
jamb and the sill with exterior grade sealant. Therefore lift
the gasket, re-install and glue it afterwards. Also fill the
space [B] underneath the vertical frame and the sill with
exterior grade sealant generous to avoid water leakage
into the wall and to protect the wood. See Illustration C1.

Apply a thick bead of exterior grade sealant with a backer
rod if needed on the joint between the sill and sub floor
on both sides along the length of the sill. Do similar for
the gaps between the head jamb and side jambs with the
opening.
Step C11
Finish any waterproofing, flashing, trim and sealant
needed around the perimeter of the opening.
Important:
Make sure any weep holes in the sill are
not blocked.

To prevent uncontrolled movement of the panels when in
open position, place appropriate door holder by others
as needed.
PROTECTION OF UNIT DURING
CONSTRUCTION PHASE
It is important that during the construction phase
the unit be kept closed, covered and protected from
damage. During this phase, a unit is often subject to the
most extreme conditions from all types of construction
operations that can permanently damage and destroy
it. A unit can be damaged by cement splatter, tar, paint,
weld splatter, falling objects, construction dust, sand
blasting, etc. All temptations to use the large opening
of an installed system for easy ingress and egress by
tradesmen should be resisted.
