2. INSTALL DUCTWORK AND ELECTRICAL WIRING
Plan where and how the ductwork will be installed. Access to the top of the hood is
preferred for connection of ductwork.
Install proper-sized ductwork, elbows and roof or wall cap for the type of blower you
are installing. If installing CP35 power pack, use 8” round ductwork and if installing
CP37 power pack, use 10” round ductwork. Use 2” metal duct tape to seal duct joints.
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.
Run 3-wire power supply cable to installation location. Its length should extend at least
4 feet below the bottom of the custom hood.
