Installation Details Continued
14) (Continued) FOR BACK VENTING APPLICATIONS ONLY. IF YOU ARE NOT BACK VENTING, PROCEED TO STEP 15.
Method 1: 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 electrical wire, lift the hood up to the wall and hang the
hood on the mounting strip, taking care to properly align the duct connection(s) between the elbow(s) and
the duct(s) in the wall.
Method 2: Lift the hood up to the wall and hang the hood on the mounting strip, taking care to properly align the duct
connection(s) between the elbow(s) and the duct(s) in the wall.
Secure the hood to the mounting strip by installing the screws (previously removed from the strip in Step 10) into the
pilot holes drilled in Step 12.
Method 2: Insert the electrical wire from the service panel into the electrical wire clamp on each motor box. Tighten
the wire clamp(s). Slide the duct cover between the ceiling and the top of the hood while aligning the flange
on top of the hood between the double flange on the bottom of the duct cover. Gently slide the duct cover
to the wall. Caution must be taken to avoid scratching the hood or ceiling.
SKIP STEP 15. PROCEED DIRECTLY TO STEP 16.
15) FOR TOP VENTING APPLICATIONS ONLY. IF BACK VENTING, PROCEED DIRECTLY TO STEP 16.
Method 1: 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 for each outlet of sufficient length to meet the duct(s) in the ceiling.
One end of the duct must be crimped to fit inside the duct in the ceiling. Insert the non-crimped end into
the exhaust collar on the top of the hood and seal with duct tape. While securing the slack in the wire, lift
the hood up to the wall and hang the hood on the mounting strip, taking care to properly align the duct
connection(s) between the hood and the duct(s) in the ceiling.
Method 2: Lift the hood up to the wall and hang the hood on the mounting strip, taking care to properly align the duct
connection(s) between the hood and the duct in the ceiling. Duct work must fit inside the exhaust collar.
Use duct tape to seal all joints.
Secure the hood to the mounting strip by installing the screws (previously removed from the strip in Step 10) into the
pilot holes drilled in Step 12.
Method 2: Insert the electrical wire from the service panel into the electrical wire clamp on each motor box. Tighten
the wire clamp(s). Slide the duct cover(s) between the ceiling and the top of the hood while aligning the
flange on top of the hood between the double flange on the bottom of the duct cover. Gently slide the duct
cover(s) to the wall. Caution must be taken to avoid scratching the hood or ceiling.
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).
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 7.
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.
