REMOTE BLOWERS (EXTERNAL AND IN-LINE)
CAUTION: To reduce risk of fi re 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 fi re, 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 effi ciently.
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.
