INSTALLATION
3
The most effective installation is one in which the back is mounted against a wall while the front is
supported by 3/8 inch threaded rod mounted to the ceiling. Wire or cable may be substituted for
the 3/8 inch threaded rod. Please see Figure 1 for recommended installation technique.

Hood Efficiency
The Canopy Hood can be extremely effective when installed correctly. The effectiveness of the
Canopy Hood is dependent directly upon the proximity of the work area to the hood face. The
face velocity and static pressure expressed in the Performance section is based on a theoretical
hood face at 1 foot below the hood. If the height of the working apparatus is below the theoretical
1-foot face, then efficiencies will drop off. Conversely, the hood will become more efficient as the
height of the working apparatus enters inside the 1-foot face.
Therefore, the distance between the work surface and the hood is extremely important. Even when
used as a multipurpose installation, it is important to be within or near the 1-foot face for
maximum efficiency for all uses. Refer to Figure 2.
