8) Remove the duct cover from its packaging. Remove and save the screws from the base of the duct cover. Place the
duct cover into the top of the hood. Attach the duct cover to the hood with the screws previously removed.
9) Lift the hood and duct cover assembly 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.
10) Remove the hood and duct cover assembly from the wall. 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. Measure this distance above the horizontal
line made in Step 9 and lightly mark the wall with a level, horizontal line. 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.
11) 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. 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. Referencing the vertical centerline from Step 10, place the mounting
strip so it is centered (left to right) on the wall in the space where the hood will be located. Drill pilot holes in the wood
mounting strip to prevent splitting. Using proper hardware, attach the mounting strip to at least two wall studs.
12) FOR BACK VENTING APPLICATIONS ONLY. IF NOT BACK
VENTING PROCEED DIRECTLY TO STEP 13.
Note: Wall studs may interfere with back venting applications.
Additional framing may be required. It is necessary to cut a
duct access hole in the wall prior to installing the hood.
Starting 7/8” above the top of the mounting strip, cut a hole 3
1/2” high x 10 1/4” wide centered on the hood centerline (see
diagram at right). Install the duct from the outside of the home
to the opening in the wall. Use duct tape to seal joints.
13) Hang 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. 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. Remove hood and drill 3/32” pilot holes at the center of marks in the wood
strip to prevent splitting.

5) Install an appropriate 1/2” UL listed electrical wire clamp through the electrical strap on the top of the hood deck. Install
electrical wiring from the electrical panel to the hood location.
Warning: Make sure power is off and locked at the service disconnecting
means on the service panel during installation.
6) Insert the electrical wire through the electrical wire clamp allowing 3” to 4” of wire for hookup. Tighten the electrical
wire clamp.
7) From inside the hood, using UL listed wire nuts, attach the “neutral” wire to the white lead, the “hot” wire to the black
lead, and the ground wire to the green lead.
Warning: Do not operate hood without proper ground connection.

All K-Series hoods have two halogen lights.
• Because the Magic Lung
®
blower uses centrifugal filtration rather than conventional baffle or mesh filters, the Magic Lung
®
blower can handle cooking equipment with higher cubic feet per minute (CFM) requirements and can deliver equivalent CFM much more
efficiently than other than other filtration systems. When comparing the Magic Lung
®
with other blower units made by other manufacturers, use the “Equivalent CFM”.
