INSTALLATION PREPARATION Installation Preparation DUCTWORK REQUIREMENTS WARNING TO REDUCE THE RISK OF FIRE, USE ONLY METAL DUCTWORK. NOTE: Read the ductwork sections only if you do not have existing ductwork. If you have existing ductwork, skip to the "Damage" section and proceed. The venting system must exhaust to the outside. This hood can be vented vertically through upper cabinets or horizontally through an outside wall. Ductwork is not included. Exhaust connection This hood is designed to be vented vertically using a 7" round duct or a 3 1»4" x 10" rectangular duct or horizontally using a 3 1»4" x 10" rectangular duct. Do not use less than a 7" diameter duct. Duct length The ducting from this fan to the outside of the building has a strong effect on the air flow, noise and energy use of the fan. Use the shortest, straightest duct routing possible for best performance, and avoid installing the fan with smaller ducts than recommended. Insulation around the ducts can reduce energy loss and inhibit mold growth. Fans installed with existing ducts may not achieve their rated air flow. NOTE: For an ENERGY STAR® model, unit must be vented mode to be considered ENERGY STAR® certified.
