Method 2:
a) 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 of the collar(s) of the exhaust outlet(s). Use
HVAC foil tape (not grey cloth duct tape) to seal 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 installing the screws (previously removed
from the strip in Step 11) into the pilot holes drilled in Step 13.
• IF BACK VENTING, SKIP STEP 15. PROCEED DIRECTLY TO STEP 16.
15. Mounting the Hood, NON-Back Venting:
If using a transition, install it on the insides of the exhaust collars and seal with HVAC tape (not
grey cloth duct tape). Then mount the hood as follows:
Method 1:
a) 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.
b) 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.
c) 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.
d) Tighten the wire clamp(s).
Method 2:
a) Insert the electrical wire from the service panel into the electrical wire clamp on each motor
box. Tighten the wire clamp(s).
b) If not using a transition, cut a piece of duct for each outlet of sufficient length to meet the
duct(s) in the ceiling.
c) 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.
d) 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.
e) 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.
f) 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 cover is used, it should be secured to at least one stud using the nailing strips.
The duct cover front panel should then be installed.
