I miss read your reply to my original post, and posted my reply. Then I saw your question afterwards. I owe you an apology, I fkd up. I think we are on the same page. Sorry brother, no excuse, I jumped before I read and thought.Excuse me Not sure how asking you to clarify your statement pissed you off but you need to lighten up. I know some inserts heat fairly well without the fan. Yes a fan will increase the output on them but as you say in some cases they are not vital. Am i not allowed to ask questions about stoves i have little experience with?
