I have decided that I am going to go with the Jotul 550 insert and I am wondering if an OAK can be used on it. I have read the debates on this forum for and against OAK's so I am not looking for another debate on OAK useage. I would really like to know if the Jotul 550 insert has a connection for one. If it does, do you use the same control to damper up and down? I already have a 3inch OAK directly into my existing firebox (traditional masonry firebox) on the bottom left side wall. I wanted to see if I could hook it to the Jotul 550? Thanks
