Best IS170 manual Install The Ductwork, Install Support System

INSTALL THE DUCTWORK

NOTE: To reduce the risk of fire, use only metal ductwork.

1.Decide where the ductwork will run between the hood and the outside.

2.A straight, short duct run will allow the hood to perform most efficiently.

3.Long duct runs, elbows, and transitions will reduce the performance of the hood. Use as few of them as possible. Larger ducting may be required for best performance with longer duct runs.

4.Install a roof or wall cap. Connect round metal ductwork to cap and work back to- wards hood location. Use duct tape to seal the joints between ductwork sections.

INSTALL SUPPORT SYSTEM

1.At hood location, install 2 x 4 cross framing between ceiling joists using dimensions shown on center.

2.Finish the ceiling surface. Be sure to mark the location of the ceiling joists and cross framing.

3.Position the support frame as shown. The UP ARROW should point towards the ceiling after installation.

4.Secure the support frame to joists and cross framing with four screws (6x70mm) and washers provided. Make sure screws are driven into center of joists and framing for maximum strength.

5.Adjust the overall height of the support frame. Loosen and re-tighten the screws in the height adjustment slots as necessary. Note that the hood height is 14- 3/16” (360mm) and that the bottom of the hood must be 24” min. and 30” max. above the cooktop.
