   Head it off -- cut stud, add header (say, double 2x4's) to bear its load, attach it to adjacent studs (toenails are probably enough, maybe hangers, trimmers/jacks if you want go nuts). Add second 2x at bottom of hole. If the wall isn't loadbearing to have even less to worry about, a 2x on the flat is plenty. Actually a header in even a loadbearing wall is probably overkill. Of course, you're having this permitted and inspected? :)

   I think you are saying this is a range hood, not just a combustion gas vent. Important point often ignored: Picture a grease fire inside the unsealed or disconnected duct, stoked by the exhaust fan, then spreading inside the wall. Not pretty, and it's what i found in my grandmother's attic (absent the fire, thank goodness). Obey Code requirement for smooth ducting (26 guage?), don't even think "duct tape," use proper termination, and keep flammables away. (I used fiberglass insulation and cement board.) Slope to allow condensation and grease to flow out. (better yet, delete greasy stuff from diet, or BBQ it, where torrents of uncontrolled flames are often expected by some)

   I need to install a gas range exhaust unit but a stud is right where the duct should go. What should I do?
