Stacks I'm talking about are hypothetical and it depends of how many floors building has... I guess not taller then 50 - 60m... but in most cases less then 10m. It also depends on which floor the stove is placed.
I don't understand the fluid dynamics that much but a good stack has a tendency of suction, and on the other hand it is much harder to set fire in completely cold stove with cold stack.
I hope someone could explain that little bit better.

I am still learning about this too. What I think I have heard is that the exhaust from rockets also tends to be cooler. Most traditional exhaust is hot or warm enough to go up the stacks due to heat rising. So you may not have enough heat from a rocket to rise very far? Maybe someone else will comment on that.
How tall are the stacks you are talking about?
