Typical Installation Methods
If the fresh air opening has not yet been made, see gures 9 through 16
for the recommended locations and the job-specic plans for the exact
location. Follow local codes.
Cut the wall opening so that it is slightly larger than the louver being
installed. For dimensions, see Table 3. If the opening is already there,
measure to be sure there is a minimum of 3/8" (9mm) clearance around
all sides. For masonry installations, a lintel must be installed above
all louvers.
In thick wall applications, the portion of the wall between the louver
and the unit is the outside air plenum. Line this plenum area with 3/8"
(9 mm) mortar or other suitable material. In some applications, the job
specications require a metal sleeve connection between the louver and
the unit. If using such a sleeve, properly caulk it to ensure a weather-
tight seal. This is critical in preventing freeze-ups, cold drafts, and air
inltration. Be sure the wall is smooth, square, and provides a suitable
mating surface.
Before setting the louver, construct a sloping, sealed cement mortar base
to drain unwanted moisture to the outside, (see gure 20). Be sure the
mortar base is 1" (25mm) thick at the unit and tapers toward the louver.
The mortar at the unit also acts as a backing against which the open
cell gasket of the unit itself can seal. This is critical in preventing water
leaks and air leaks under the unit. Be sure the sealed cement mortar
base is smooth and ush with the interior wall.
If it is not possible to construct a sloping mortar base, then eld-supplied
ashing is required. See gure 21. The ashing should terminate ush
with the exterior of the building. Place a bead of caulk under the ashing
to prevent moisture from wicking back to the unit. Do not caulk the
joint between the louver and the ashing. This joint is designed to let
unwanted moisture escape.
