Had a mix of Hickory and some maple ( MM- from 16 to 18%) got good fire going, probably the best I have had in awhile. Stove cruising at about 520 for quite awhile, flue temp (single wall) about 285. Got busy doing some stuff and when I checked this is what I saw. Secondary still burning a lot, lots of coals. Some blue, yellow and some orange flames in the wood. Wondered what could cause this dark brown just in this corner. Never had it before. Will do the dollar bill test later when stove is a bit cooler. I had done it a few weeks ago and it was fine.
Dark brown in the corner?

I can't really answer your question but I get something almost identical towards the end of the burn. The lower corners of the door and the top of the air distribution plate on either side of the doghouse will get covered in a very light brown ash. I haven't had the door get that dark but it will go away once I get the stove hot on the next reload.

If it's not a gasket leak you starved your stove out of air. It happens to me I can have a secondaries from hell well over 600 and if I close it too much I get a brown spot.

usually has to do with lack of draft. Increase the draft it will air wash itself away.
Maybe it is the draft. I did push the control knob in further than I have before. Usually have it just even with the lip but like I said went in a bit more. Coals have burnt down and will try again ... will see what happens.

it happens to me when I got the daft too low. I've had the whole glass covered. I've got it figured out now to where I can set it and it will not happen.

I get this same effect with my Oslo . . . same spot every time. I've checked the gasket in the past with the dollar bill test and all was good . . . as other folks mentioned . . . I surmised it might have been a case where the air wash wasn't as strong in that area. Typically I see this if I've turned down the fire a smidgeon too much.
Must have been what it was. I didn't turn it down as much and the stove burned great and brown spot all gone!! Thanks everyone.
If the occurrence is random it could be that split was a bit closer to the glass and a bit less seasoned than the others. Hickory needs a couple years to fully season.

Thanks, I am thinking it was a combination of the Hickory (which might not have been quite ready) and pushing the air in to far. Hasn't happened again. Going to -13 here tonight so hoping me and the stove get it right.

x2 for the lack of airwash theory in that area. Ive had that since day one and i think i burn cleanly. On my stove, as you turn down the primary, the airwash is really just centered, not evenly distributed

If you haven't seen it before, I'd guess the wood type and greener wood is the cause. Keep the butt ends away from the glass and burn hotter. I just cleaned my stove after burning three single digit days last weekend. Burned hot, reloading at 350. The glass hardly had white haze.
