Hi! I am new here but have been reading threads for a while now, I recently purchased a, Federal Air Tight stove model # Fa264ccl. I am in the middle of getting it ready to for my living room to be installed front.of a prexiisting fireplace. My stove exhaust pipe points straight up, I would like to have the stove sit out in front of the chimney opening far enough that I can use the side door to load and mount the blower on the side. My question is if I start from the top of the stove with an 45 degree elbow will this hurt the stoves performance? Thanks in advances for any ideas!
