So this is a new to me stove (and wood stoves in general) I took it all apart and gasketed most of it (what was bad) and resealed stuff. Replaced the insulation around the cat. The cat was perfectly clean when I bought it from the previous owner. The chimney and all that is new construction.
This is after a good 30 minutes of good burn with flue temps in the 4-500 degrees according to the thermometer. I attached pictures of the different stages
Good flame is with: Damper open, Bypass open, Ash pan cracked
Next one is with: Damper open, bypass closed. Ash pan cracked
Starting to die out: Damper open, bypass open, ash pan closed
Out but glowing: everything closed except damper

The damper doesnt seem to really have any effect on it. Maybe If I had good flames it would...

Any ideas?

First off i would bet your wood is not dry enough. How long has it been cut split and covered? Do you have a moisture meter?

But from there how tall and what type and size is your chimney?

What temperature is it outside?

And lastly never start the stove by cracking the ashpan. That will crack the bottom of your stove

Also is that a magnetic surface thermometer on doublewall pipe?

Wood is around 16-20% according to my meter. Temp outside is in the 50's. Chimney is about 10' of double wall up to 4 feet of triple wall that sits about 2 feet above the peak with a "deluxe" rain cap. all 6"

good to know about the ashpan, just crack the door then? the ashpan just seemed to work better without any smoke coming out a cracked door

I was told its been seasoned 2 years. I pushed the tongs in as far as i could.

The magnetic surface is on the adapter, so I believe its single wall at that point. But when i had the thermometer on a double wall section, the results were the same

With double wall pipe your flue temp are much much higher than the reading you are getting. You need a probe thermometer. If you are taking a measurement without splitting the wood right before you are getting a misleadingly low reading.

okay. So you think its a wood issue? I'll split some and re-measure next weekend and see what I get. We have bought a lot of wood over the past few years (at our home just for a fireplace, non essential heat) and keep getting wet stuff even though they say "seasoned and dried". Also where would I put the probe thermometer so it doesnt leak anywhere?

Why is this so dang hard to find?!?! haha

What do you mean so it doesn't leak? Your pipe is under a vacume and leak will be in not out. But if you still the right size hole the amount of air leakage will be very minimal

These stoves are also very temperamental and hard to run
