I’ve never run an F55, but those numbers look good to me, it’s possible the stove is just too small for your needs.So I went out and bought a new thermometer for the stove pipe. It is a Ventis brand that measures the actual stack gas temperature, rather than that of the metal pipe. I started a fire about two hours ago and the basement was at about 65 degrees. Ran it as hot as I could and put in fresh splits N/S as needed. Although I only have one wood moisture meter that I bought from Lowe's and therefore cannot vouch for its accuracy, I don't think that the problem is wet wood. All of my wood is in a wood shed and has been since at least June. The wood itself, according to my firewood dealer, was cut and split in the summer of 2017. All I can say is that I know what wood that hasn't been properly seasoned burns like, smells like and feels like, and this isn't it.
The fire has now been burning for 2.5 hours. I've tried running it with a cellar window cracked open for more air and with different combinations of the air control and the flue damper. The only observable effect is that the air control has speeds or slows combustion the quickest (obviously) and the damper seems to slow the combustion while keeping the temperature up.
After 2.5 hours the stovetop is cruising at 450 degrees after peaking at between 550 - 600 for awhile and the flue gases briefly hit 1000 degrees before settling at 750 degrees where they are now. The basement temperature rose during that period from 65 to 76 degrees and the first floor went from 65 to 68 degrees. All this while the outside temp is 50 degrees and rainy.
If this was my old stove, it would be very warm throughout the basement and into the second floor. I guess the only thing left from the above suggestions is to find a manometer and check the numbers on the flue draft.
On firewood, one fall and winter outside, followed by one summer in the shed, is pretty marginal for hardwoods. Most here will target at least two full summers for medium hardwoods, and three summers for oak, locust, or Osage. But I don’t think this is your problem with getting heat, your stovetop numbers look good.
