Installation Details
1) Read all instructions thoroughly before beginning installation. Note: These instructions apply to standard hoods only.
Custom hoods may require additional specification consideration.
2) When installing a CIEH9/CILH9 island hood, it is recommended that the bottom edge of the hood be located no more
than 30” above the cooking surface. Exceeding recommended mounting height may compromise performance.
3) Load-bearing framework in the ceiling is necessary for installation. Additional framework
construction may be required. Do not attach an island hood to a structure that cannot support
twice the weight of the hood. If applicable, remove the duct cover from its packaging and
remove the hood-mounting screws from the base of the duct cover. Install the duct cover to
the load-bearing framework in the ceiling using appropriate hardware through the four inside
corner mounting flanges on the top of the duct cover.
4) Install the duct(s) from the outside of the home down to the location of the exhaust outlet(s)
on the top of the transition plus 1”. This will allow the transition to engage 1” inside of the
duct. Consult connection diagrams (on next page) for further details on exhaust outlet
placement.
Use duct tape to seal all joints. A complete listing of available Vent-A-Hood ducting materials is provided on the back
page of this instruction sheet.
Transition heights are as follows:
Island Dual Blower (T200):
8” round duct connects to 9” tall VP565 transition (included).
Island Dual Blower (T2+200):
Two 8” round ducts connect to two 9” tall VP565 transitions (included).
5) Prepare a protective surface on the floor or countertop for the hood. Remove the hood from its packaging and place it
on its side on the protective surface for access to the inside of the hood. Remove the blower shields (A) by loosening
the two brass screws on the bottom of the shield. Gently close the back draft dampers from the top side of the hood.
To remove the blower housings, unsnap the suitcase latches (B) (one on each side of the housing). The housings
should be pulled forward and gently “tipped” to clear the blower wheels and then out of the hood. Place the hood
upside-down on the protective surface.
