I removed an old 1980s prefab fireplace and cut the pipe to do so. Now I am trying to figure out how to get the bottom section removed. I can't figure out how it comes apart or what brand it would be. I attached pics, any suggestions would be appreciated!

Detach it from the prefab and lift up.
So unfortunately I already cut it with a sawzall so now I have to detach the section that I cut cut doesn't seem like it wants to twist off, can't figure out how to detach that piece.
Can you post a picture of the prefab ZC top where the chimney pipe is attached?
Can the remaining chimney be lifted out of the top of the chase?
Yes I could but I'd like to use the pipe that is there and just figure out how to detach the bottom section to add to it
You need to find a label to figure out what brand pipe it is if fittings are available and if it's rated for the required temps needed for a woodstove
