Basic Door Installation
Step 3
When securing the pan in the
opening, do not puncture with
nails as this would be a possible
source of water instruction. Use
a wide headed nail (like a roofing
nail) to secure the top of the side
dam to the jamb framing, as
shown.
Place flexible flashing down each
jamb over the sheathing allowing
the flashing to wrap inward to
cover the framing, as well. The
jamb flashing should be long
enough to overlap the side dams
of the pan.
Place flexible flashing across top
of opening, overlapping the jamb
flashing, and wrapping under to
cover the header of the rough
opening framing. 
Step 4
Place Weather Resistive Barrier
(WRB) over face of wall.
Cut WRB to opening height and
width, as shown.
Take care when affixing the WRB
to the wall not to rip or tear it,
especially near the flashing at the
jambs and header. This will limit
any potential water penetration
through the WRB.
