So here is my problem.. I just bought a new Blaze King Ashford 30 to replace a very old Orley's model. We have a stone/block double flue chimney that is lined with clay. The chimney runs three floors from the basement to roof (of course) and the stove that we are replacing is on the second floor. My problem is that the specs for the Blaze King says that I need to have at a minimum 24" spacing from the top of the stove to the bottom of the horizontal stovepipe after the elbow before it enters into the chimney. As it is now, with the new stove sitting on the hearth pad I have 16" from the top of the stove to the bottom of the pipe. Do I really need to cut a new hole into my chimney and cap the old one just to make up the extra 8"??? or can i get by with the existing hole? Any advice would help. Thank you very much.
Do I REALLY need to cut my chimney??

Cutting a new hole isn't as easy as it sounds. Do you know what size flue tile you have? If it had a liner I wouldn't be too concerned, but it might be a bigger issue if the clay is oversized. Kind of like 2 strikes against you, ya know?
I like that solution. However, it is going to be important to know the ID of the clay chimney liner, the distance between the stove top and the top of the chimney and whether this is the only thing connected to this chimney. If this is a large tile, going up only 10-15ft and there is something else also using this chimney, the odds are that the stove will not draw properly. Modern stove chimney requirements are very different from the old Orley.

With two stories, sounds like you have may enough height and draft that 18" would still work (provided that, as begreen implied, the inside dimensions of the clay liner aren't too big.) I would put in a stainless liner for better draft and easier cleaning, but that's a bit pricey up front. Worth it in the long run, IMO....
I may have read it wrong. The OP says the stove is on the second floor, thus my concern of height.
