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 CWEH9 wall mount hood, it is recommended that the bottom edge of the hood be located no more
than 27” above the cooking surface. Exceeding recommended mounting height may compromise performance.
3) Select the appropriate installation method. Method 1 allows the hood and duct cover to be installed together as a
single unit. The final duct connection is made at the ceiling as the hood is attached to the wall. Method 2 allows the
duct cover to be slid into place after the hood is attached to the wall. Caution must be taken when using this method
to prevent scratching the top of the hood or the ceiling.
4) IF THE HOOD IS TO BE “BACK VENTED”, PROCEED DIRECTLY TO STEP 5.
Consult the connection diagrams (on next page) for further details on exhaust outlet placement.
Method 1: Install the duct(s) from the outside of the home to the ceiling over the exhaust outlet(s) on the hood. The
end of the duct(s) should extend 1” below the ceiling.
Method 2: Install the duct(s) from the outside of the home down to the location of the exhaust outlet(s) on the top of
the hood.
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:
Single Blower (B100):
6” round duct will connect directly to the top of the hood.
Dual Blower (B200):

Single and Dual Blower (B100 & B200): 6” round duct will connect directly to the top of the hood; 8” round will
