https://www.hearth.com/talk/threads/liner-size-issue.172387/ I have been advised that there's virtually no chance of fitting a 6" liner down my brick chimney. I'm now considering where to fit a prefab.
The main house is 3 floors and the addition is 2 floors with a roof deck(porch) on top. Running the chimney from the basement up through the addition would avoid the more formal rooms in the main house, but it would have to come up through the roof deck.
Assuming all clearances are met and the 10-3-2 rule is applied is this safe? The 4x4 in the pictures is the approximate location where the chimney would penetrate.![[Hearth.com] Class-A chimney thru roof deck?](https://www.hearth.com/talk/data/attachments/235/235895-39a44c62bdfbdd4b5b823486ed7cde2e.jpg?hash=URY4rPztx_ "[Hearth.com] Class-A chimney thru roof deck?")
