Vent Mode
In vent mode, installation can be done with or with-
out the riser. You must consider 3 1/2" riser height in
determining the hood installation height.
To determine the hood installation height with riser:
X = C - (A + B + R + Y + Z)
Example: X = 96" - (36" + 10 1/2" + 3 1/2" + 15" + 6")
X = 25"

To determine the hood installation height without
riser:
X = C - (A + B + Y + Z)
Example: X = 96" - (36" + 10 1/2" + 24" + 0")
X = 25 1/2"
NOTE: Installation height should be measured from
the cooking surface to the bottom of the hood. The
vent hood must be installed 24" min. and 36" max.
above the cooking surface. The hood installation
height, from the cooking surface to the bottom of the
hood, depends upon ceiling height and other factors
which must be considered .
