I know there have been some threads on flue temps, but wanted to try to get some info. I am running the Osburn 3300 and am running a surface temp reading of about 400° to 450° on the Rutland burn indicator. The pipe is single wall 22 gauge so imagine the actual flue temp roughly 1.7 or 2.0 times that? I actually put in a key damper and have damped it down about 2/3 closed. The stove top temp is cruising at about 625° with the air fully closed and the secondaries doing pretty well. I have a half load of oak cutoffs in the stove now. Do these stove pipe temps seems reasonable or too high? Not sure how I could get them any lower, but definitely higher than what I got on the old Defiant. The pipe isn't crackling or popping or anything. Thoughts?
