Ventilation in the home is a critical component for healthy living, especially as our structures become more airtight. Without good ventilation, toxic stale air simply gets recycled through the lungs. And having proper airflow in the kitchen is important so that moist air and odors from cooking get properly expelled. Without adequate air circulation a number of problems can occur. This would include mold growth from moisture and sickness or even death caused from breathing toxic fumes. Whenever a gas range is used, it has the potential to bring both the fumes of natural gas and dangerous carbon monoxide (the byproduct of burned fuel) directly into the living space. This is why the building code demands proper ventilation for the kitchen.
In the slideshow, “Updraft Ventilation”, you'll see the basic steps for installing an island updraft ventilation system. The unique nature of this installation was that the center of the hood location landed directly on the hip of the roof creating a very complicated process. No doubt this is the reason why the individual who remodeled the space failed to install ventilation altogether, and simply left the problem for the next homeowner.
