FPX44 or other flue exhaust soot issues

[ironmanco]

We have an FPX44 and have been noticing that we get pieces of soot (film-like) that come out of the flue and blow around. They not solid enough to pick up but when you try the pretty much just disintegrate in your hand. the flue is properly capped and screened. Not sure what this is from. We burn a mix between pine and local hardwoods and typically burn in the 800f range with sometimes bumping up to the 1000f range. I do also damper it down for slower burns.

Any ideas?

Reviving this thread. I'm still having this issue. Here are a few images of what I'm seeing. It's pretty widespread. Note that this is more like a film and there are hundreds of these all over. Some are rather large maybe 1-2" across while most are smaller "flakes". I'm burning all seasoned hardwood so not quite sure what's going on.

How do you determine that your wood is "seasoned"? Those temps are also rather high, where are you taking them?

Moisture meter mostly measuring <12%. Those temps are when I'm running it wide open from the cat thermometer integrated in the unit. I would say it runs typically in the 500-700 range most of the time depending on the amount of wood in the box.
