It is good that you did a thorough combustion chamber clean. Depending on how much you are burning will determine how often you clean it. That’s where the manometer comes in. You will see the draft creep closer to zero. Once you get to the edge of the recommended range, that’s when you do a total clean. For me it is about once a month. The other thing you need to clean are the vents that lead from the combustion chamber to the direct vent. Here is a pic of mine without the ash pan.

You can see it starting to build up in the openings. You need to vacuum that out but also get up into the vents with a brush. Here is one I have. You wouldn’t believe how much ash collects up in there until you get the brush. I didn’t know any of this last year when I started. It is a learning process!
Just bought same brush and fiberglass cane. i did get up into those canal, but had a surprise. about 4 inches of the rest of a tubing disintegrated that fell on the bottom of the stove. This means that this tube is falling apart. I felt it at the beginning of the vent from the bottom. What happens if this goes up even further ?? any way this can be corrected, or replaced. What will be the implication long term? can the co2 in the stove mix with fresh air around the stove that goes to the top with the air that is heated?

That doesn’t sound good. Are you sure the vent disintegrated or is it just old buildup that broke free? You don’t want the combustion exhaust getting into the convection chamber. That would push co2 into the house. I’ve not experienced this level of deterioration on a stove. Maybe someone else can chime in.

went into trashcan and picked up these small pieces that seem to be rusted and decayed metal and there was and additional piece of 3 x 5
I don't have a big magnet to verify 100% metal but has the shape of a tube so did the big piece and it's rust color and brittle, breaks in layers when I break it.

My girlfriend touched the switch by mistake stopped the stove, and is now cold. I will get down on my knees and try to put my hand inside the bottom vent to see if by chance it would be metal build up or my vent that is disintegrating.

That could be just built up ash and corrosion. It is hard to tell from the pic. I would think it would take a lot of abuse to have those vents corrode all the way through to another chamber. The build up could explain your baro difficulties. I remember you saying the stove was used. Any idea how old it is or how well it was taken care of? Hopefully someone else will chime in with a similar experience.

Sorry. I just looked back at the beginning of the thread and it sounds like you said this was a new install. If that is the case, then that must be ash build up. Not sure why it would look like that in just a month of use. Again, maybe someone else has some thoughts.

fiew !!!! got a big scare !!! after putting a flashlight up directed at vent and extending arms to film with cell, got a nice view of the intact vent with some crud still left in there but most of it i was able to clean!!!! you can see a small patch of dirt left on the right side. I put the cell twice in there to move the flashlight a bit to give me a better view. And you can hear me clean the lens of the cell.
The second vent was even cleaner, almost no ash came out of this vent, and seems clean.

New install close to 10 year old used , was used only on week ends in a summer house, so in theory close to new condition. With what i removed which scared the bejesus out of me had quite a buildup of hardened ash. Still needs to be cleaned again as I can see from my professional hand shaking video lol there is a small patch on the right side up in the vent.

And I don't have baro difficulties lol just don't have the proper baro with the .02 indicator and bought the brush and fiber glass rod but waiting on manometer.

That’s good news! That could have been 10 years of ash and corrosion. It makes sense. See if it runs better now. The manometer will be a big plus too!
