I am about 2 weeks into owning this stove. It’s the first epa stove with burn tubes in the top that I have owned. My previous stove was a epa rocket stove. I could really use some help figuring this thing out. So I can start a fire in the nc13 with no problems. I let it heat up to 400 and close the air a 1/3. Then when it hits 450 another 1/3. And at 500 I close it to about a 1/8 inch from fully closed. And the stove jumps up to 600. Then on a hot reload it’s nothing for it to hit 660 with the same process on shutting it down. Englander told me anything over 600 is an overfire. My setup is a 16 foot straight up and out the roof. Single wall pipe to the tripe wall thru the attic. My wood has seasoned for a little over a year. One burning mostly ash and walnut. And sometime a piece of oak that’s a year and a half old. It seem no matter what I do I can’t keep the stove away from the 600 degree mark. I would like to stay around 500. So does this stove just run that hot or am I doing something wrong? My stove pipe was inspected last year and the sweep said everything was great and a prefect install
