Installation Instructions

Page. 11
Preparing the ceiling cutout
and housing
The unit must be mounted to the surrounding housing.
See “Installation considerations” on page 6 for
suggestions on determining hood height.
When calculating the load for the housing support system,
be sure to include the weight of the ventilation unit. See
“Unit weight” on page 6 for unit weight.
Build housing in accordance with the dimensions noted in
“Ceiling Cutout and Supporting Stud Housing
Dimensions”.
For optimal performance, the hood should be mounted
flush against the back wall. In such installations, the rear
trim piece may not be necessary.
For installations of ½'' – 3'' (13 – 76 mm) from the back
wall, the rear trim piece can be used.
