INSTALLATION
(CONT.)
Cut around the outside of the traced line(s), avoiding wall studs. Install the duct from the
outside of the home to the opening in the wall. Use HVAC foil tape (not grey cloth
duct tape) to seal joints.
Proceed to step 14.
Method 2:
Using the applicable venting accessories and the connection diagrams (previous page) as a
guide. Install the duct(s) from the outside of the home to the wall so they will meet the
exhaust elbows to be used.
The end of the duct(s) should extend 1” past the ends of the elbows.
Proceed to step 14.
13. Check mount holes to wood strip, drill if needed:
Hang the hood on the mounting strip by aligning the channel at the top of the back of the hood
over the wood mounting strip on the wall.
While holding the hood in place, determine if the mounting holes in the channel at the top of
the back of hood align with the existing holes in the mounting strip. If they don’t, mark the
hole locations on the mounting strip.
Remove the hood and drill 3/32” pilot holes in the center of the marks in the wooden mounting
strip to avoid splitting.
14. Mounting the Hood:
FOR BACK VENTING APPLICATIONS ONLY. IF YOU ARE NOT BACK VENTING, PROCEED
DIRECTLY TO STEP 15.
• If using a Hestan duct cover, it must be mounted to the hood using the provided fasteners before
continuing.
Method 1:
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 the collar(s) of the exhaust outlet(s). Use HVAC
foil tape (not grey cloth duct tape) to seal joints.
b) 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.
c) 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. Caution must be taken to
avoid scratching the hood or ceiling.
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 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.
