INSTALL THE DUCTWORK
NOTE: To reduce the risk of fire, use only metal ductwork.
1. Choose the location where the exterior blower will be mounted. See illustra-
tions 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 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 adapter as close to the range hood as possible.
