Well, I have been reluctant to post my fix as I'm sure it won't impress a few people... mine was pretty cut and dry once I found the issue.
So, my first sirocco 30.1 had a blatant missed weld that immediately caused leaking creosote and was replaced by BK. Problem solved right? nope. While the odor was less apparent on the second stove it was still present to some degree. I assumed this must be wood burning and I felt bad already so "live with it" or don't burn is what I thought.
I replaced my door gasket with the high density white one in a attempt to fix it. It helped, but on high, hot burns (like when cleaning the window) or when throttling up the stove there was a very clear smoke odor. And I mean clear, not "is it the paint curing" or "maybe there was some smoke spillage the last re-load" type smell. Enough my neighbor would try and find my issue every time he came over...
I hadn't burned the stove since the cold spell in the end of Dec start of Jan as the odor was getting to me a little. We went to whitefish Montana and stayed in a log cabin two weeks ago with a wood stove, I cringed when others wanted to light it.... As I lighted it I noticed the split doors, top door, side door etc.... "ughhhhh this thing is going to smoke up in here terribly" I figured.... Not a hint of smoke. Not once, ever. I realized I wasn't being too picky and I do indeed have a issue at home with my stove.
So when I got home the investigation started, these things aren't Rocket appliances' (Ricky'ism
). Here's what I ened up finding after combing it over with a flashlight and fine tooth comb.

The corners rely on 100% weld penetration to seal the stove. the front and rear plates extend past the side plates about 1" on each side. BK welds the entire side plate perimeter, and the front and rear plates top (external) and bottom (internal). This leave the back side of the front and rear plates un-welded for about 1".

Not a big deal right? its external right? You have left the thickness of the front and rear plate material non-welded. Sure its only the fit up gap but clearly from the creosote in all 4 top corners of my stove shows this. The green line is where I welded to fix my smoke smell issue in all 4 top corners and bottom corners.

The red arrows represent the 4 corners that had visible creosote leaking. The green arrows are corners that have the same weld issue but showed no leakage.
I ended up dragging in my welder and buzzed a 1" bead in the 8 corners after covering all the floors, other surfaces, removing paint ect.
after painting it back up and no other changes I ran her with ZERO smell
, then, the next morning, I ran a full load on high for 3-4 hrs..... zero smell. I then climbed up on the roof, and removed the 6' of extra class A I put on (looks so stupid sticking out of my roof 10') and ran the stove on high and low.... Zero smell.
I'm back to only ~15.5' total chimney, I put the screens back on my chimney cap, I've ran it a week high and low..... with absolutely zero odor.
And I mean zero. None, zip zero.
Sure I welded on it, sure I probably fawked any warranty but I could care less. It leaked before and now it doesn't.
End of story.... check these corners for any creosote?
