EXTERIOR OR IN-LINE BLOWER SELECTION
CAUTION: Either an exterior blower or in-line blower may be used with this hood.
The IEX42 hood must be installed with blower models EB6, EB9, EB12, EB15, ILB3,
ILB6, ILB9, or ILB11 only. Other Blowers cannot be substituted (Blowers sold
separately).
The blower 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. Choose the location where the Exterior or In-Line Blower will be mounted. See
illustrations below for mounting location suggestions and restrictions.
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 long duct runs.
4. After the Exterior or In-Line Blower has been installed, connect round metal
ductwork and work back towards the hood location. Use duct tape to seal joints
between ductwork sections.
5. An 8" round to 10" round transition (Model 414) is required. For best air
performance, install the transition as close to the range hood as possible.
