DM Brick Ledge & Crown Caps
flashing should fit to the outside of the alignment grooves on top of the DM outer casing. Continue the DM chimney up
to the required termination height.
Once the masonry veneer is in progress, the inner flashing is set into a horizontal joint in the veneer at a level above all
other roof deck flashings, chimney-to-roof flashings and counter flashings. Weep holes should open to the outer face of
the veneer at vertical mortar joints located at the level of the inner flashing
(Figure 42)
.
Where moisture may develop between the DM outer casing and the chimney veneer, inner flashings as described
above will help to divert such moisture to exterior face of the veneer by way of the weep holes and thereby keep such
moisture from working its way down between the veneer facing and the DM outer casing and into the interior of the
structure below.
DM Small Crown Cap
The DM small crown cap is a prefabricated cement weather cap that measures 26- 1/2” square and 3” thick. The
small crown cap is designed and installed the same as the large crown cap.
(Figure 43)
The small crown cap is intended for use where DM chimneys are to receive thin veneers and cultured stone that
do not require the installation of the Isokern brick ledge. The small crown cap is also suitable where DM chimneys are
to receive a stucco finish. Other chimney terminations are possible with DM chimneys. Check local codes for use of
custom chimney terminations and decorative shrouds.
DM Large Crown Cap
The DM large crown cap is a prefabricated cement weather cap for masonry veneer chimneys. The large crown cap
measures 37-1/2” square and is 3” thick at its center.
(Figure 44)
The component has an octagonal hole at its center so that the top inner liner of the DM chimney stack can pass
through it. The crown cap then sits on the top most DM outer casing block.
To set the large crown cap the last inner liner should be at least 3” above the last outer casing block in the chimney
stack.
Mortar the top of the last outer casing block. Set the large crown cap over the inner liner and onto the top of the last
outer casing in the stack.
Caulk or mortar the joint between the octagonal liner and the crown cap where the liner comes through the top
surface of the large crown cap.
