I have a hearthstone shelburne in my masonry fireplace, connected to flexible stainless steel liner. Chimney is 25ft and not feasible to clean from the top.

To connect the stove to the liner/adapter, the installer used single wall stovepipe cut to length. The stove was pushed into place along with the straight single wall stovepipe. I won’t be able to easily disconnect the stove to clean out the flue or the catalysts, and ideally I’d like to reposition the stove a little to get it centered better.

I purchased a double wall adjustable stove pipe (DSP6AL-1 11-18”) but it’s a few inches too long to work for my application. I need something more like 8”-12”, but not seeing that option anywhere.

Any thoughts/suggestions?

It looks like Metal Fab's 6DWA18 might work. Call them to verify.
