I'm replacing my 20 year old wood stove and favor the Lopi Leyden at this point. The chimney connector is 6" and attaches to the Duravent chimney at the ceiling, 8' above the floor. The old connector was a straight vertical run between stove and ceiling. The Lopi stove dimensions are a bit different from the original stove, and in order to maintain the required 16" hearth clearance in the front, the connector pipe ends up about 2" farther back than the original stove. So, in order to keep the connector pipe vertical, I have to somehow make up the 2" offset. I understand this is normally done using 45 or 90 degree elbows. Can either of those be adjusted so that a 2" offset could be handled? Would 2 elbows be necessary? Any other suggestions?
