Due to concerns about earthquakes, I've decided to terminate my firebrick
chimney at six feet, (nine feet above the ground) and finish the final six
feet with a single wall stainless chimney of the same dimensions as the
interior of the fire brick. My question is will I encounter any problems with
this? Will it effect the draw? I like the idea of being able to take the
metal part down between firings. I'm also afraid a firebrick chimney wouldn't
last long in our two hundred plus inches of rain. Any input will be greatly
appreciated.

I used a 4' section of scrap cast iron sewer pipe on my reduction kiln. It work
great. No problems. I have found a 10' section of the same in a scrap yard and
am going to get it for the stack on the soda kiln I am in the process of
building.
I would reconsider removing the pipe between firings. It doesn't seem worth the
effort if you guy it well. But, then, we do not get too many earthquakes in
Georgia, either!

In response to your question about draw, I can tell you that the longer/higher
your chimney, the stronger the draw. If you shorten your chimney it will slow
down your heating time. Hope this is the answer you were after.
