8. Mark the wall at the lower edge of the hood opening as follows:
a) Remove the duct cover from its packaging and remove the mounting screws from the base
of the duct cover.
b) Place the duct cover on the top of the hood and secure it using the mounting screws
previously removed.
c) Lift the hood and duct cover to the location on the wall where it will be installed and
lightly mark the wall with a short, horizontal mark along the bottom edge of the hood.
9. Find and mark location of mounting strip as follows:
a) Set the hood down so its back is accessible.
b) On the back side of the hood, measure the distance between the bottom edge of the hood
and the top edge of the wood mounting strip.
c) Measure this distance above the horizontal mark made in Step 8 and lightly mark the wall
with a level, horizontal line.
d) Measure where the center (left to right) of the hood will be and mark the upper, horizontal
line on the wall with a short, vertical centerline.
10. Attach the mounting strip to the wall as follows:
a) Remove the screws inside the top of the back of the hood that retain the wood mounting
strip that is recessed in the mounting channel. Note: Some retaining screws may be
located behind the blower(s).
b) Remove the wood mounting strip from the back of the hood and place the top edge of the
strip on the upper, level, horizontal line on the wall.
c) Referencing the vertical centerline from Step 9, center the mounting strip on the wall (left
to right) in the space where the hood will be located. Mark the strip at two or more stud
locations, and drill clearance holes in the wood strip to prevent splitting.
d) Using proper hardware, attach the mounting strip to at least two wall studs.
11. FOR BACK VENTING APPLICATIONS ONLY. IF NOT BACK VENTING, PROCEED DIRECTLY
TO STEP 12.
• Note: Wall studs may interfere with back venting installations. Additional framing may be
required. It is necessary to cut duct access hole(s) in the wall prior to installing the hood.
a) Remove and set aside the duct cover that was installed in step 8.
b) Hold the hood on the mounting strip by aligning the channel at the top of the back of the
hood over the wood mounting strip on the wall.
c) Place the appropriate elbow(s) on top of the hood in line with the hood exhaust collar(s).
On the wall, trace around the elbow(s). Remove the hood and elbow(s) from the wall.
d) Cut around the outside of the traced line(s), avoiding wall studs. Install the duct from the
outside of the home to the opening in the wall. Use foil HVAC tape (not grey cloth duct
tape) to seal all joints.
e) Place the duct cover back onto the top of the hood and reattach it to the hood.
12. Mark screw holes in mounting strip:
a) While holding the hood in place, mark locations on the mounting strip through the two
mounting holes in the channel at the top of the hood. Some mounting holes may be
located behind the blower(s).
