I had some choke cherry that I had cut into 18" logs and stacked early April - I split it about 3 weeks ago with the intent to save it for next year but found the moisture in the middle of the splits to be 21%. Decided to use it now and noticed some smokey burns when running in the low air mode. I have a regency I3100 insert that I run 15 min at full air then 15min at 1/2 air before I choke it down to the low burn setting. Split some of the largest pieces and verified the 21% in the middle but as I move to the outside of the piece I notice moisture at 27 % and above. I thought that wood seasoned from the outside-in mine seems to be seasoning from the inside- out. Whats going on ??
