Vermont Castings Aspen

[dkuntz413]

I have a friend with a Vermont Castings Aspen that vents 6 inches at rear. The piece that goes from the stove to the metalbestos class a pipe is only 6-8 inches long and is single wall.The metalbestos is 8 inch. So its a 6 inch at the stove going to 8 inch at the class a. This adapter should be a class a pipe. Also where it fits on the collar on the stove, it fits on the outside of the stove collar, which is wrong,it should go on the inside. Can someone steer me to a company that sells this please. The stove has been running for a year with the single wall, but for my piece of mind, I want to get the right class a adapter/increaser.
Final question- do the creosote cleaning logs do any good, and if so, is there a better brand?
Thanks

It's a bit hard to figure out the piping based on the photo, is the left photo rotated 90 deg.? Normally this requires a wall thimble - http://www.ventingpipe.com/metalbest-8t-iwt-8-class-a-chimney-pipe-insulated-wall-thimble/p1070034

For class A pipe, the minimum clearances are 2" to combustibles for class A. That includes wood, sheetrock and rags. For peace of mind check that. It looks closer than that in the photo.

Its not rotated, and clearances are 2 inches. I just need to find the class A 6-8 inch increaser that is about 6 inches long

I don't think Selkirk makes that part in class A. But they do make a DSP double-wall increaser. It may also need an adapter to fit the stove's flue collar.

The general consensus is that the chimney sweeping logs may help convert the hard, glossy creosote into a more easily sweep-able creosote, but a) there is no substitute for physically sweeping the chimney with a brush and b) it is far better to burn seasoned wood and burn at the proper temps to reduce creosote build-up.
