14) FOR BACK VENTING APPLICATIONS ONLY. IF YOU ARE NOT BACK VENTING, PROCEED DIRECTLY TO STEP 15.
Method 1: Place the appropriate elbow(s) on the top of the hood. Elbow(s) should be placed with the non-crimped
end(s) on the inside the collar(s) of the exhaust outlet(s). 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(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 11) into the pilot holes drilled in Step 13. If applicable,
slide the duct cover between the ceiling and the top of the hood back to the wall and attach the duct cover
to the hood through the knockout holes using the mounting screws previously removed in Step 9. Caution
must be taken to avoid scratching the hood or ceiling.
Method 2: Place the appropriate elbow(s) on the top of the hood. Elbow(s) should be placed with the non-crimped
end(s) on the inside the collar(s) of the exhaust outlet(s). Use duct tape to seal joints. If applicable, attach
the duct cover to the hood using the mounting screws previously removed in Step 9. 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, 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) on the hood 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 11) into the pilot holes drilled in Step 13.
SKIP STEP 15. PROCEED DIRECTLY TO STEP 16.
15) If applicable, install the transition on the insides of the exhaust collars and seal with duct tape.
Method 1: 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. Secure the hood to the mounting strip by
installing the screws (previously removed from the strip in Step 11) into the pilot holes drilled in Step 13.
Use duct tape to seal joints. Insert the electrical wire from the service panel into the electrical wire clamp
on each motor box. Tighten the wire clamp(s). If applicable, slide the duct cover between the ceiling and
the top of the hood back to the wall and attach the duct cover to the hood through the knockout holes from
inside the hood using the mounting screws previously removed in Step 9. Caution must be taken to avoid
scratching the hood or ceiling.
Method 2: 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
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 fit inside the duct in the ceiling. Insert the non-crimped end over
the transition or into the exhaust collar(s) 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 in the ceiling. Secure the hood to the
mounting strip by installing the screws (previously removed from the strip in Step 11) into the pilot holes
drilled in Step 13.
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 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.
