General Information
The ventilation unit is designed for installation inside a custom-built hood and
chimney assembly. It is for ducting to the outside; It cannot be used in conjunction
with a recirculation unit.
Installation height above cooktop is the user’s preference. The lower the hood
above the cooktop, the more efficient the capturing of cooking odors, grease, and
smoke. This hood has been approved for installations as low as 30” (760 mm) and
as high as 36” (900 mm) above the cooktop. The lower height may be inconve-
nient for tall people and large cooking vessels.
