to rear) with angles facing toward rear (outside).
2. Position the case angles vertically on each side of the wall sleeve to provide a level
installation.
3. Mark the wall sleeve through the holes in the case angles.
4. Drill 5/32" diameter holes at marked locations on the wall sleeve.
5. Assemble the angles using only 10x1/2" screws. Install the screws from the outside of the wall
