Installing new chimney and stove pipe to wonderluxe stove.

[ScottChristian]

Wanting to replace
Old 12.5 in galvanized chimney outer pipe that held the 8 inch single wall,
To a 6 inch ss chimney,. Then into a double wall black stove pipe.
Then to a T section(dvl-t) that connects to stove vent.
Haven't torn into anything yet. But wondering what a huge hole there must be at the roof. Hope it's not much more than 13". But it may be.
Will the flashing that comes with dt620 kit cover such a large hole?
What is best way to make this large hole a tighter fit to a 6dt-60sscf pipe as well as the roof flashing that comes in the kit.....
+- a 15" hole to the duravent 8" diameter

Check with Duravent support. I think the flashing is about 20" wide and 27"? long. If that won't work it may be better to get the parts individually. Duravent makes a large base flashing if needed.

Is this for a different chimney?

I'm ripping out old chimney that had the single wall running up through it. The ceiling box is awful looking at the least
