4. IF THE HOOD IS TO BE “BACK VENTED”, PROCEED DIRECTLY TO STEP 5.

Consult the connection diagrams (following) for further details on exhaust outlet placement.

Method 1: 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 or to the transition (if applicable).

• If a transition is used, install duct down to the location of the transition outlet plus 1”.

This will allow the transition to engage 1” inside of duct.

Method 2: 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.

• Use foil HVAC tape (not grey cloth duct tape) to seal all joints. See “VENT ACCESSORIES” on

page18 for a listing of available Hestan ducting materials.
