15. Mounting the Hood, NON-Back Venting:
If applicable, install the transition on the insides of the exhaust collars and seal with HVAC tape
(not grey cloth duct tape).
Method 1:
Lift the hood (and duct cover, if used) 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 HVAC tape (not grey cloth 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).
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 “Transition heights:” on page12
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 HVAC 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. If a Hestan duct covers is used, it should be secured to at least one stud using the nailing strips.
The duct cover front panel should then be installed.
17. 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).
Do not operate hood without proper ground connection.
18. Install the blowers motor(s) by plugging the wiring connectors in and securing the blower
motor(s) using the retaining screws that were removed in Step 7.
19. Replace the blower housing(s) and the blower shield(s). Make sure that the damper(s) open and
close smoothly.
20. Turn power ON, verify operation: See “Using the Ventilation System” on page5 for proper
hood operation. Test all blower and light functions to ensure they are operating properly.
