and sleeve.
•
To ensure the unit’s maximum efficiency, the sleeve must be installed with a
slight downward pitch from the indoor side to the outdoor side (Fig 6), then
fasten the wall sleeve (Fig 7).
•
Lintels should be used to support the block above the wall sleeve (Fig 8). The
sleeve can not support the load of bricks/blocks (if directly under a window sill,
use of lintels may not be necessary).
Note: The fastening parts and wood screws etc. are supplied by the end user.
5. Weather proofing:
Weather proofing gaps between the exterior wall and the sleeve with caulking or other
equivalent weather proofing materials (Fig 9).
Note: Installation in extra thick walls:
•
If the sleeve is being installed in a thick wall where the sleeve is recessed more
than 3”, an extended wall sleeve will be required with depths as called out in
chart 1.
