Yes it is only an in and out adjustment. I used it on my set up. I put my thimble in the ceiling and secured the first piece of dbl wall ss in the thimble then was able to adjust the telescoping piece to the right length.
You can see that I extended it about 8 or so inches. You can also see the end of the fiberglass roping that I stuffed around the bottom since I didn't want to use any silicone so that it would be easy to pull apart. Which I have done several times. I have actually clogged the hole in the cone of the cyclone ash collector twice. How I don't know. Plus I have taken the pipe off to inspect it and it was just dusty, no creosote.
The supplier claims it is stainless on the inside and only black pipe on the outside. Maybe I will take it apart again(only takes 2 minutes) and see if a magnet sticks to the inside.
So hows the install going.
We need updates with pics
