Venmar CPM SERIES Installation Instructions Manual - 1. Prepare The Installation
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 CPM1 power pack, use 8” round ductwork
and if installing CPM2 power pack, use 10” round ductwork. Use 2” 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.
