Installation Details
1)  Read all instructions thoroughly before beginning installation. Note: These instructions apply to standard hoods only. 
Custom hoods may require additional specication consideration.
2)  When installing an island range hood, it is recommended that the bottom edge of the hood be located no more than 
30” above the cooking surface for optimum 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 anges 
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 the 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 height is as follows:
Island Dual Blower (T200):  8” round duct connects to 9” tall VP565 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.
