A stainless steel insulated chimney would not last very long
on most wood kilns. At cone 10 I can have flames coming
3 feet out of the top of my 13-foot tall chimney - it would
disintegrate a metal stack quickly.
Since you already have a 9" (not 9/2" I presume) -by- 13 1/2"
brick chimney, I would recommend you continue with that.
Even if I had to buy more bricks and the SS pipe was free that's
what I'd do.
Except for maybe the tiniest of kilns, 9" X 13 1/2" is the smallest
size a chimney for a wood kiln should be. When I rebuilt my
kiln I increased my chimney from 9" X 13 1/2" to 13 1/2" X
13 1/2", and it improved the kiln.
The last 5 feet of my stack is homemade castable refractory,
cast inside cardboard Sonotubes and sheathed in sheet metal.
It has held up great for 7 years now. For step-by-step instructions,
See my article in Ceramics Monthly:
"Casting a Chimney", February 2001, pages 102-104.

I need to add about 2-3 feet to my chimney for my wood burning kiln to be
well clear of the roof. Our newspaper delivery man got all interested in
what I was building and gave a 3 foot stainless steel insulated chimney
piece. It has an inside diameter of 10" but my flue up to the 12 1/2 foot
level on the inside is 9 1/2 x 13 1/2" - so the stainless is about 60% of
the area.

how do you get up there to roast wienies and toast marshmallows, then?
Step ladder, scaffolding, skyhook?
Or just a REALLY long stick?

I suggest scaffolding. The effect is unpalatable however.

Hello,
some tool rental businesses also rent scaffolds.
Maybe going thru the yellow pages to find one
would be a good thing.
