> I still haven't heard a practical reason this matters
Newbie myself here on the forum, though I have been wood heating about 25 years. , There are topics on that here. Two good reasons:
1) embers and smoke go up and away instead of being blown down onto the roof. I have noticed the longer an ember falls, the more likely it will be extinguished when landing on a surface.
2) you get outside the envelope-vacuum all structures have, so, you are not sucking the exhausted fumes back into the house. This is how people kill themselves with ICE generators.
Then there is the draft aspect and back draft.
