INSTALLATION
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 11
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. 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 aligning the mounting holes with the holes in the
mounting strip and installing the screws previously removed from the strip in step 10.
16. CONNECT ELECTRICAL:
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).
Do not operate hood without proper ground connection.
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.
BACK VENTING
When venting out through the wall, one or two elbow fittings are required, depending on the
blower configuration::
ELBOWS FOR 600 AND 1200 CFM
Hoods with 1200 CFM blower systems use two sets of elbows and fittings, one for each 600 CFM
blower unit.
ELBOWS FOR 900 CFM
Units with 900 CFM blower systems use one set of 600 CFM fittings and one set of 300 CFM
fittings.
