10) Remove the screws inside the top of the back of the hood that retain the wood strip that is recessed in the mounting
channel. Note: Some retaining screws may be located behind the blower(s). 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 9, place the mounting strip on the wall so it is centered (left to right) in the space where
the hood will be located. Drill pilot holes in the strip to prevent splitting. 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 a duct access hole in the wall prior to installing the hood.
To accomplish this, rst remove and set aside the duct cover that was previously installed in Step 8. 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. Place the appropriate elbow on top of the hood in line with the hood exhaust collar. On the wall, trace around
the elbow. Remove the hood and elbow from the wall. Cut around the outside of the traced line, avoiding wall studs.
Install the duct from the outside of the home to the opening in the wall. Use duct tape to seal joints. Place the duct
cover back onto the top of the hood and reattach it to the hood.
12) 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. Some mounting holes may be located behind the blower(s). Remove hood
and drill 3/32” pilot holes at the center of marks in the wood strip to prevent splitting.
13) FOR BACK VENTING APPLICATIONS ONLY. IF NOT BACK VENTING, PROCEED DIRECTLY TO STEP 14.
Place the appropriate elbow on the top of the hood. The elbow should be placed with the non-crimped end on the
inside the collar of the exhaust outlet. Use duct tape to seal joint. Insert the electrical wire from the service panel into
the electrical wire clamp on each motor box. Tighten the wire clamp(s). While securing the slack in the wire(s), lift
the hood up to the wall and hang the hood on the mounting strip, taking care to properly align the duct connection
between the elbow on the hood and the duct in wall. Secure the hood to the mounting strip by installing the screws
(previously removed in Step 10) into the pilot holes drilled in Step 12. SKIP STEPS 14 AND 15. PROCEED DIRECTLY
TO STEP 16.
14) Insert the electrical wire from the service panel into the electrical wire clamp on each motor box. Tighten the wire
clamp(s). Cut a piece of duct of sufcient length to meet the duct in the ceiling allowing room for the transition (if
applicable). If a transition is used, cut the duct to reach the transition outlet plus 1”. This will allow the transition to
engage 1” inside of the duct. See Page 3 for transition heights. One end of the duct must be crimped to t inside the
duct in the ceiling. Insert the non-crimped end over the transition or into the exhaust collar on the top of the hood and
seal with duct tape.
15) While securing the slack in the wire(s), lift the hood up to the wall and hang the hood on the mounting strip, taking care
to properly align the duct connection between the hood and the duct in the ceiling. Secure the hood to the mounting
strip by installing the screws (previously removed in Step 10) into the pilot holes drilled in Step 12.
16) From inside the hood, using UL listed wire nuts, attach the “neutral” wire(s) to the white lead(s), the “hot” wire(s) to
the black lead(s), and the ground wire(s) to the green lead(s) inside the motor box(es).
Installation Details Continued
Warning: Do not operate hood without proper ground connection.
17) Plug the motor(s) into the hood and reinstall the blower motor(s) using the three retaining screws that were previously
removed in Step 6.
18) Replace the blower housing(s) and the blower shield(s). Make sure that the damper(s) open and close smoothly.
19) Refer to the Owner Maintenance Guide Operating Instructions for proper hood operation. Test all blower and light
functions to ensure they are operating properly.
