INSTALLATION
b) 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 YOU ARE NOT BACK VENTING, PROCEED DIRECTLY TO STEP 15.
a) Place the appropriate elbow on the top of the hood. Elbow should be placed with the
non-crimped end(s) on the inside of the collar(s) of the exhaust outlet(s). Use foil HVAC
tape (not grey cloth duct tape) to seal all joints.
b) Insert the electrical wire from the service panel into the electrical wire clamp on each
motor box. Tighten the wire clamp(s).
c) 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.
d) Secure the hood to the mounting strip by aligning the mounting holes with the holes in
the mounting strip and installing the screws previously removed from the strip in step 10.
IF BACK VENTING, SKIP STEPS 14 AND 15. PROCEED DIRECTLY TO STEP 16.
14. NON-Back Venting:.
a) Insert the electrical wire from the service panel into the electrical wire clamp on each
motor box. Tighten the wire clamp(s).
b) Cut a piece of duct of sufficient 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
"TRANSITION HEIGHTS:" on page 12
c) 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 foil HVAC tape (not gray cloth duct tape).
15. Hang the hood:
a) 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.
b) Secure the hood to the mounting strip by aligning the mounting holes with the holes in
the mounting strip and installing the screws previously removed from the strip in step 10.
16. WIRING CONNECTION:
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).
17. Plug the connectors for the motor(s) back into the hood and reinstall the blower motor(s) using
the retaining screws that were 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. Turn Power ON, verify operation: See "USING THE VENTILATION SYSTEM" on page 5
for proper hood operation. Test all blower and light functions to ensure they are operating
properly.
(CONT.)
DO NOT OPERATE HOOD WITHOUT PROPER GROUND
CONNECTION.
