2. INSTALL DUCTWORK AND ELECTRICAL WIRING

Plan where and how the ductwork will be installed. Access to the top of the power pack is preferred for connection of ductwork.

Install proper-sized ductwork, elbows and roof or wall cap for the type of power pack you are installing. If installing EC621306SS single blower power pack, use 3¼” x 10” ductwork. If installing EC622301SS double blower power pack, use 10” round ductwork. Use 2” metal foil duct tape to seal duct joints.

We recommend to install the power pack at a minimum distance of 24” from an electric range and at 30” from a gas range.

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.
