I have Selkirk double wall pipe for a stove installation. There's not much to the product besides an outer 6-1/2" black pipe and an inner 6" Stainless Steel pipe with both ends crimped and the outlet end having two rivets holding the pipe together.
My problem is, I set the stove to the proper clearances and ran the double wall pipe to the point where I need one more piece before tieing into an insulated wall thimble. I finally received the wall thimble this afternoon and it's alot bigger than I thought. Not to mention, Selkirk doesn't have detailed dimensions on their insulated thimble.. After installation, I'll only need a 3-1/2" to 4" piece of pipe. Shortest selkirk sells is 6"
Using a 6" piece, I'd have to push the stove out 2" to 2-1/2". This would push the stove out too far for the required front hearth protection.
Why can't both pieces of pipe be removed from another and shortened on the non-crimped ends, then re-fastened to obtain the desired length. The 1/4" airspace will still be between the two pieces of pipe.
