Install question?

I am installing my stove this week. I am handy enough to handle the install plus I already checked with building inspector and my insurance company. My question is I am installing the stove in a corner with two outside walls, Once I set the stove where I want it to clearance codes and line up my vent pipe, what do I do if I end up at a wall stud where i need to cut? move the whole stove? or cut the stud and support it? any other suggestions? instead of a 45deg. should I use a flex pipe?

Thanks

Thats what I was thinking but I was hoping to avoid it. LOL, less cutting the better plus my walls do not have todays 2 X 4's they still have the bark on two sides. the house was built in 1885. I just have to hope when I get it all in place that I clear the 2 X 4 studs.

Thanks
