EXTERIOR BLOWER SELECTION

This product is designed for use with the EB6, EB9, EB12 or EB15 Exterior Ventilators.

The exterior ventilator must be UL listed for Canadian and U.S. use, and evaluated for use with solid state speed control rated 120V, 60 Hz, 6.0 A max.

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 the exterior blower. Connect round metal ductwork to exterior blower and work back towards hood location. Use duct tape to seal the joints between ductwork sections.

5.An 8” round to 10” round duct adapter (Model 414) is required. Install adapter as close to hood as possible.
