    Right where I want to be.
    Something else to consider...........some manufacturers have a distance from stove top to ceiling clearance requirement that needs to be checked and adhered to.

    You are very close to the minimum. I've done 2 chimney setups with the IS just like yours. My new one has 19ft outside and a relatively long horizontal piece and it works- but another couple feet would be nice. I'm off the floor 3.5 inches, and two notches from the highest setting. (Two inches?). If you are going to raise the stove over a foot from that I would add to the top of the chimney if possible. If you can just put another piece on top anytime you could try it out first but I think you will be doing that in the (on the) end. Let me know how it works out though.
    I believe stoves like this prefer some vertical run before a 90degree bend, especially with a marginal chimney.

    Our Fireview is on a 16" raised hearth and the firebox door is 9 1/2" from the top of the hearth, so 25 1/2" from floor to bottom of firebox door. We find this to be ideal for this stove. We sit on a chair to load the stove.

    The IS with the legs fully extended is 15 1/2" from floor to bottom of firebox door. With that, it would seem to me that a 12" raised would work great.

    williaty the guys like to pick on me. It is hard to see my avatar but I sit on a milk crate when splitting wood. Just something the guys picked up and like to throw around. No harm done. The picture below shows it better. This is just how I've found it the easiest way to split wood. If I have to lift the block, that is, to turn it, I can place my elbows on my thighs and lift; sort of like a lever and fulcrum. That way it does not hurt the back.

    Once the hole is cored through the concrete I'll be able to see how high the outside chimney will be. Right now it looks like ~12' to the roofline and I bought another section to take it 3' higher. That could easily turn into 17-18' when it's all done.

    Do you have to clear any overhang? When you start going through a studded wall, 8 inches of foundation, and an offset, you have a long horizontal run. Add the 2 90 degree bends and you want more than the minimum height. I can't say what you can get away with but I can say my 21ft of total rise works okay. I saved another 4ft in case I needed it but it looks like I am okay. In the mid 30'sF it was sluggish and I had some smoke spillage. Once it gets under 30 it draws well. FWIW I have an OAK.

    I have a 12" hearth. Works great. A 24" hearth would be easier to set on. Hmmm

    No overhang on the roof. Chimney will be very close to the house. I will only have a 12" horizontal run plus the 90.

    Just make sure that horizontal has at least an inch of pitch.. helps smoke go out and I think is code... just get nervous when people say horizontal..

    Code say 1/4" per foot for horizontal. We are about 1/2" per foot and it works better.

    That will definitely help. I'm interested to know how it works.
