There was no impact on ductwork and the window is operable, so gives natural ventilation.

Terrific innovative kitchen. How well does the BlueStar range function? I'm a Viking, Capital, Wolf loyalist. Currently building two kitchens in our home. How happy is the homeowner with the BlueStar product line? Thank you in advance. Ness in Texas

I love this space. I also want to know about the impact of the hood at the window. Did it take a special kind of ductwork?

Thanks! It did not take special ductwork. Exhaust hoods either exhaust out the back or up and out, and exhaust rises. We have installed clerestory windows above a range hood before, and that required some custom solutions.

I think the venting questions are related to these codes. The answer would be to simply have the outdoor exhaust be 3' above the window or on the roof.
