Installation Details
1) Read all instructions thoroughly before beginning installation.
2) When installing an IZTH island hood, it is recommended that the bottom edge of the hood be located no more than
30” from the cooking surface. Exceeding recommended mounting height may compromise performance.
3) Load-bearing framework in the ceiling is necessary for the installation of an island hood.
Additional framework construction may be required. Do not attach an island hood to a structure
that cannot support twice the weight of the hood.
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 anges on the top of
the duct cover.
4) Install the duct from the outside of the home down to the location of the transition outlet 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 listed 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 Cluster Blower (T400): 12” round duct connects to 11 1/4” tall VP564 transition (included).
5) Prepare a protective surface on the oor or countertop for the hood. Remove the hood from its packaging and place
it upside-down on the protective surface for access to the inside of the hood.
