I'm searching the forums, trying to read as much as possible. One thread that caught my eye was a discussion on flue length and the poster having difficulty controlling fire within their stove. Ours will need to be about 20-25ft, should this length be a special consideration and therefore limit my search to particular brand or type of stove? We originally were leaning towards a Lopi but was concerned when I read the poster having issues with Lopi and their tall flue.
