INSTALLING THE DUCTWORK:
INTERNAL BLOWER
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 using a minimum
6” round duct 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.
4. Install a roof or wall cap. Connect round
metal ductwork to cap and work back
towardshoodlocation.Useducttapetoseal
the joints between ductwork sections

REMOTE BLOWERS (EXTERNAL AND IN-LINE)
CAUTION: To reduce risk of fire and electric shock, install this range hood only with External
Blower Model CBE-1000, and In-Line Blower Model PBN-1000A. Other blowers cannot be
substituited.
INSTALLING THE DUCTWORK: REMOTE BLOWER
NOTE: To reduce the risk of fire, use only metal ductwork.
1. Choose the location where the External Blower or In-Line Blower will be mounted. See
illustrations below for mounting location suggestions and restrictions.
2. A straight, short duct run using a minimum 8” round duct 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 External 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.

INSTALL THE HOOD
Remove the plastic protective film from all
exteriorsurfaces,ductcoversandfilters,prior
tofinalinstallation
1. Construct wood wall framing that is flush with
interior surface of wall studs (Fig.22/23).
Make sure:
a) the framing is centered over installation
location.
b) the height of the framing will allow the hood to
be secured to the framing within the
dimensions shown.
2. Determine desired height over cook top
and mark hood bottom line. Install drywall
anchors and 4,8x38mm screws per
dimensions shown in Fig. 22/23.
3. Hang the hood onto the screws.
4. Tighten mounting screws. Add additional
screws through hood body as needed for
additional support.
Notes:
a. Minimum hood distance above cook top
must not be less than 24”. A maximum of
36” above cook top is highly
recommended for best capture of cooking
impurities. Distances over 36” are at the
installer and the users discretion; and if
ceiling height and flue lenght permit.
