I got my Englander 13-NC installed over the weekend. Everything went pretty smooth. My only issue is my liner comes through my damper area of my fireplace at a slight angle and will not attach flush with my flue collar on the stove. I have attached some pics of the angle of the liner. Do you guys think I will be ok with a 15 degree elbow adapter? I already ordered one from Woodland Direct and just want to make sure it will work before it ships!
