STEP 3
Installation of the case in the wall opening
1. Positionthecaseintothewall.Refertocharton
page1forroomsideprojection.Therear(outside)
edgeofthecaseshouldextendatleast1/4″ beyond
the outside wall to be able to caulk properly and
prevent sealing the drain holes in the rear flange
of the case, and to facilitate easy installation of
an accessory drain, if desired. (If it is desired to have
the rear grille flush on the outside, a drip rail must
be installed under the case and caulking applied
between the drip rail and case.)
IMPORTANT: Install case level from side to side
and with a slight tilt from front to rear. Use a level;
no more than a 1/4 bubble will be the correct case
slant to the outside.
2. Firmlysecurethecasetothewallstructure.
Do not drill any holes in the bottom of the case.
3. Caulk the entire opening on the outside between
thecaseandthebuildingexterior.
4. Caulk the entire opening on the inside between
the case and the building interior.
Use lintel, when required, to support brick and block
above the case.
NOTE: Do not drill any holes in the case for electrical
connections.
STEP 4
Weatherproofing
Weatherproofgapsbetweentheexteriorandinterior
walls and the case with caulking or equivalent
weatherproofing material.
* NOTE: It is critical to caulk around perimeter of
wall case on all four sides on the outside and the
roomside where it joins the building to prevent air
and water infiltration.
For installation in extra thick walls
1. The case should not be installed in a thick wall
wherethecaseisrecessedmorethan3″.
2. If the case is being installed in a wall where
therecessis3″ or less, flashing must be installed
underthecaseandextendup2″ on each side.
The flashing must include a drip rail as illustrated
in the figure below.
* NOTE: It is critical to caulk around perimeter
of wall case on all four sides where it joins the
building to prevent air and water infiltration.
