I have a newly installed auber temp probe about 6” above my insert. Now that I have had a few fires I am trying to find the sweet spot for closing primary air and not wasting heat up the flu. I realize that my probe is a bit close to the stove, but with it being an insert, that was all the space I had to work with. When starting a fire or on reloads I am having a hard time keeping the flu temps below 850-900 peak temperature. Doesn’t this seem a little too high? Also, as I close the air down to control temps and slow the burn, I oftentimes end up with dirty glass on the lower half of my door. The secondaries are burning vigorously and the primary is shut down enough to not keep the lower part of door clean. Not sure what I need to do? My wood is dry, I can rule that out.
