You either know or your about to find out. The stove pipe is high as hell. Not sure how much you will need but the triple wall just to get it from stove to outside will be a kick in the pants. Depending on how close you run it to the exterior wall may have to continue on up past roofline. Just running it past roof isn’t good enough. There are formulas for how high the termination cap must be based on roof pitch and peak of roof. If you don’t adhere somewhat to the formula you will end up having drafting issues and Smokey fires in the basement. You also need to see if you can extend it far enough from exterior wall that you miss your eve. Or you may go through it but that is extra bucks on the wall thimble and stove pipe. I would say to get a pro to give it a look but most won’t touch it if it’s not new or bought from them. If you were heating a detached barn or garage I would say go for it a d see how it does. But because it is your home I recommend proceeding with caution. The stove itself I wouldn’t worry about after fixing the crack. It’s the expense of stovepipe gives me pause.
