Installation Details Continued
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.
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.
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 next to the blower. Remove the hood and drill 3/32" pilot holes at the center of the marks in the
wood strip to prevent splitting.
13) FOR BACK VENTING APPLICATIONS ONLY. IF YOU ARE 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 collarof the exhaust outlet. Use duct tape to seal joints. 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 and the duct in the wall. Secure
the hood to the mounting strip by installing the screws (previously removed from the strip in Step 9) into the pilot
holes drilled in Step 12. Insert the electrical wire from the service panel into the electrical wire clamp on the motor box.
Tighten the wire clamp. Caution must be used to avoid scratching the hood or ceiling.
SKIP STEP 14. PROCEED DIRECTLY TO STEP 15.
14) 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 from the strip in Step 9) into the pilot holes drilled in Step 12. Use duct tape to seal joints. Insert the electrical
wire from the service panel into the electrical wire clamp on the motor box. Tighten the wire clamp. Caution must be
used to avoid scratching the hood or ceiling.
15) Using appropriate mounting hardware, attach the duct cover to at least one wall stud through the mounting strap in
the top of the back of the duct cover.
16) From inside the hood, using UL listed wire nuts, attach the white, “neutral” wire to the white lead, the black, “hot” wire
to the black lead, and the ground wire to the green lead inside the motor box.
17) Plug the motorinto the hood and reinstall the blower motorusing the three retaining screws that were previously
removed in Step 6.
18) Replace the blower housing and the blower shield. Make sure that the damper(s) open and close smoothly.
15) Replace the duct cover front panel by aligning the snaps and pressing each snap into position.
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.
Warning: Do not operate hood without proper ground connection.
