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. Choose the air
outlet location. See Fig. 3.
2. A straight, short duct run using a minimum 6” round duct (10” round duct for the dual
blower) 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.

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 (10” round duct for the dual
blower)willallowthehoodtoperformmost

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 cap. Connect round metal
ductwork to cap and work back towards
hood location. Use duct tape to seal the
joints between ductwork sections (Fig.4).
5. The blower can be rotated according to the
air outlet location. See Fig. 5 and 6.

PREPARE THE CEILING
OPENING
The hood should always be centered over the
cooktop. Make sure there is adequate space
in the ceiling structure to install the hood and
ductwork. The hood should be mounted 48” to
72” above the cook top for best removal of
cooking impurities.
Use joist size lumber to frame in around the
range hood opening. The ceiling structure
must be able to support the weight of the hood
(64 pounds). Fig 7.
PREPARE THE HOOD
SUPPORT
Construct a wood framing system as shown
in Fig. 9.
The structure must be capable of supporting
its own weight, plus the weight of the hood (64
pounds).
