We have identical wood heaters one in the house and one in the studio. You take out two bolts and the heater will either vent out the back horizonialy or straight up. The one in the house goes into the flue horozonaly then turns straight up in the wall and out the roof. one turn up. The one in the studio goes straioght up and out through the roof. The straight out lights easer, burns better, less problems. The one in the house is a little harder to light and does not burn as well. If I ever have another wood heater anywhere it will go straight out. No 90 degree anywhere If you have to have use as few as possible

I understand what your saying.We're not sure if we are going to use this Flue.If we don't we're going to put a Flue using Triple Wall in another room the only reason I won't go straight up again is getting everything sealed around the Pipe.

I was always told to avoid 90 degrees if at all possible- use 2- 45's with a short run of pipe, or whatever- just trying to keep a "flow & rise" going w/o the restriction and "bottleneck" of a 90.

+1 Typically, the "experts" recommend no more than two 90º elbows. However, as Truckdriver pointed out, many times you can accomplish the same thing with two 45º or even two 30º elbows.

I think it probably depends on how well your system draws. If it draws well you will probably be OK. If you have a poor draw this will just exacerbate it.

The folks who are working on rocket mass heaters say that each 90 degree elbow equals 10 feet of (horizontal) run.
