INSTALL UPPER DUCT COVER
■ Place the tall duct covers onto the top of the hood.
This section has venting holes on one end.
NOTE:
If you are installing this hood for
recirculating operation, place the duct covers onto
the hood with the venting slots at the top.
If the hood is vented to the outside, the holes
should be positioned on the bottom.
■ Secure the sides with 6 screws installed through the
cage nuts.
■ Raise the assembled duct covers to the top, against
the ceiling.
■ Match mounting holes, one on each side. Install
screws through the duct and into the support.
