Installing this stove hood is quick and easy. The FIT system eliminates measuring, cutting and filler strips for a smooth fit every time. Once installed, the hood vent kitchen fan operates at a quiet 56 dBA (2.6 sones) at its lowest of two fan speeds so it won't disturb family time in the kitchen. Plus, incandescent lighting helps you keep a close eye on food so each dish turns out the way you want it to. And when cooking introduces steam, grease, smoke or odors into the surrounding air, a 190 CFM motor class takes care of it.
