Ducted range hoods are hoods that vent outside your home.

They can go through your cabinetry ceiling or straight through the wall behind the hood. Exhaust hoods over ranges once considered an accessory have become standard equipment in modern kitchens.

The range sits on an exterior wall so heading though the wall would give the run a 90 degree turn and about 2 of ducting. The range hood vent uses ducts that are made to run in the roof or walls. This type is most effective in eliminating damp and stale air that accumulates in the kitchen.
