1. SELECT BLOWER OPTION AND INSTALLATION TYPE
1.2 DUCTED INSTALLATION
Either UP27I or UP27E Series range hoods may be ducted. For a UP27E Series range hood, either an exterior blower or
in-line blower may be used. The Best by Broan UP27E Series must be installed with blower models ILB3, ILB6, ILB9,
ILB11, EB6, EB9, EB12 or EB15 only. Other blowers cannot be substituted. (Blowers sold separately.)
Plan where and how the ductwork will be installed.
NOTE: There is no horizontal exhaust on UP27E Series range hood.
If installing in-line blower, refer to instructions packed with in-line blower and follow steps 1 up to 3, 5 up to 10,
and 12 and up of this manual.
Install proper-sized ductwork, elbows and roof or wall cap for the type of blower you are installing. Use metal duct tape to
seal duct joints.
1.3 ALL INSTALLATIONS
The minimum hood distance above cooktop must not be less than 24’’. A maximum of 30” above cooktop is highly
recommended for best capture of cooking impurities.
Distances over 30” are at the installer and users discretion.
1.1 NON-DUCTED INSTALLATION (ONLY FOR UP27I SERIES HOODS)
The non-duct kit ANKUP Series (sold separately) must be installed. This kit fits hood from 30-inch width up to 48-inch
width. See installation instructions included with the non-duct kit ANKUP Series.
