I am completing a kitchen renovation that included new cabinets. The layout was changed slightly to allow for cabinet symmetry, which was a bad choice it seems. I want to install an OTR microwave, and I discovered that the old rectangular vent penetration is both 6" lower than required and offset by 3" horizontally - of course with a stud blocking the way.
1. How does one deal with the stud problem? Changing the cabinet layout is not an option at this point.
2. Assuming #1 can be fixed, can rectangular elbows be used to allow for venting out the current opening to avoid making new holes in the side of the house?
3. If 1 or 2 won't work, am I restricted to recirculation mode? Venting up is not an option.
