Apologies that link was broken -- but that was a "Commercial Style" stove for a home, not actually a commercial appliance. In any case vents are a really bad solution.. but they're inefficient at removing fumes, are usually undersized and too far from the cooking surface, and most people don't use them because they're obnoxiously noisy when running at the proper speed.

A friend of mine just remodeled their kitchen -- they got all the permits and sign-offs, and their AHJ allowed a gas stove in the island with no venting at all. Inspector told them they should open a window if they were doing a lot of cooking. It's actual madness.
