Help with double wall on blaze king

[BobFalfa]

So after a few years of only having a single wall section of flu pipe coming off the blaze king to my class a chimney i decided to change it out for a piece of double wall. So i have the new sections of double wall but now i am unsure of how to connect it to my ceiling connector. The new flu pipe is too big to right. I have posted a couple pictures. That show the new pipe and where it needs to be connected. Thanks

Here is another picture, showing the old piece that is stuck in the new double, iam pretty sure this isnt the way it is supposed to be either

Are the Chimney system components by Security?

 

[BobFalfa]

The new pieces are, but iam not sure what the other stuff is. It was all here when we bought the house.

The stovepipe should be 6" ID. What is the OD of the ceiling support stub?

 

[BobFalfa]

The new piece has an ID of almost 8 1/4” while stub is 8” OD

 

[begreen]

That is a little odd. The catalog shows 8" ID for that pipe.

Here is a picture

Same ID on both ends?

 

[BobFalfa]

Yes

That is a double-wall adjustable length. I've never used it, but according to the literature it is designed to slip over regular stove pipe.

Providing you have matched up the correct diameters, the ID on Security's double-wall pipe should be just slightly larger than the flue adapter poking down. At the top of the flue adapter, you will notice a raised bead. When you push the pipe overtop of the extension, this bead should seal everything up. Drive three 3/4" self-tapping screws (instructions may say two) through to fasten pipe to extension.
