I put the stove in indirect, closed the damper to 45 and kept the primaries open about 1/2 inch. The top of the barrel got up to 550. When that happened I closed the damper fully as well with all the primary and secondary vents, but it's been holding at 550-600. Is this normal? From what I've been reading it sounds like people burn in the 350-400 range. I've got everything shut tight and it's not dropping over the last 30+ minutes.
Don't worry these stoves are fine at 600 degrees. You need another thermometer for the stove pipe. Put it about two feet up from the top of the stove. When you do that then you can monitor efficiency the more difference between the one on the stove and the one on the stove pipe gives you how well your stove is running.
You have a lot to learn.
Be patient and remember we are always here to help you as you learn.
Thank you William. Shouldn't I be able to damper it down so the temperature is 300 on the barrel? I didn't want to add more than a few inches of coal because I was afraid it would keep going up and I wouldn't be able to control it. I have double wall pipe coming out of the stove then it T's into class a so a thermometer wouldn't get an accurate reading. I couldn't touch the double wall and even the class a was hot. I guess it's possible my thermometer is off. It's reading 100 now and the stove is cold, but they may all be like that? I'll check one at the hardware store and see.
I could also hear the air being pulled through the stove pipe (I believe) when it was stuck at 550-600.
Do you think I have an air leak somewhere? When I would burn bio bricks it would go really high too until I blocked the ashpan with a solid piece of steel I fabricated in the shape of a wood burning plate. I looked a little last night for cracks but it was so hot I couldn't stay close. I just looked now and don't see any stress cracks.
There's a 1/8 inch gap seam where the collar on the backpipe slides into the collar on the stove barrel (picture attached). Should I cement there? Are there any spots which should get cement? I've done the areas around the collars, but that's it.
Here's the damper I installed (picture attached). I noticed the damper wasn't really centered, but maybe that's normal?
My primary vents look tight (picture attached).
I'm definintely missing something. I'm going to hold off on the second fire until I hear from the forum...
