Does this work? Or is this cap too close to the pipe? (Drolet 1800i on 25’ of flex pipe)

And this creosote?… I’ve only been burning for maybe 6-8 weeks.

If you have no smoke roll out when you reload, it's fine.
Seeing the shiny black I think your wood is not ideal. Or you're choking it down too much.
Any build up there is going to eventually block the flow.

So burn better or better wood and it'll be fine if you don't have smoke roll out now.
Once you do notice some smoke rolling out when reloading, go up to clean the cap and flue as you're likely starting to constrict the flow.

Okay thanks, I went ahead and put the ugly cap that came with my kit on there so there was no question about obstructing flow.

I think I may have in fact been damping the air down too soon.. the stove thing is brand new to me! I’ve been taking the air down as soon as the logs are all black and rolling? How about overnight?

That’s been a real challenge for me.. i load it up on top of an already hot bed and then close the air down all the way?

The wood I’m pulling from is 20% or drier for the most part.

(That’s from my second load…after I bought and stacked 4 cords of oak that won’t be ready until next year. )
 
Someone else will know better how to dial in your stove.

One question I have is how you know that it's 20%?
I presume measured. How did you do that?
 
Okay,.if the pins are in deep enough,.and the wood is not frozen that sounds good.

I suggest to wait for ebs-p to get some pointers on running it a bit better for your long burns, as it's likely there that the issue is.

25' of flex should draw pretty well unless there is negative pressure in the room. Are you loading E/W or N/S? How thick are the splits? If loading E/W, try N/S if the splits are short enough. If not, try putting two sleepers (maybe 1" thick sticks) down first, about 8" apart, then stack E/W on top of them. That will allow air to get under the fire for a hotter start.

I need a damper with 23’ of insulated liner. I have maybe 4.5” to the multi flue cap. It runs fine. The liner to cap clearance is not responsible for the buildup IMO/experience.
