I have an F55. I find it (with roughly 5' of DSP going into appx 18' of metalbestos HT chimney) loves to run N/S. In fact, with very dry wood, loading the firebox N/S can (in my experience) rapidly run into an overfire situation without the secondary air shut all the way down. Caught me off guard a few times where I loaded it up, went outside quick to restock my wood supply, and came back in to find my flue temps over 1200 degrees. Never had the stove glow though
Since the primary air inlet is in the center front of the stove, if you place a piece of wood directly in front of it, you end up with a "blowtorch" effect where the stove will burn a hole right through the center of the wood.
Once I observed this, I found my "ideal" operation for long burns seems to be the bottom row installed n/s (to facilitate primary air flow from the front center inlet to the rear of the firebox) and then all my subsequent rows installed e/w so the stove will not run too hot and will get a good overnight burn with a nicely stacked firebox.
I can't say I have ever gotten a 10 hour burn time... probably closer to 4-6 with a good bed of coals at 8. Usually (since I'm not home during the day) I will fire up the stove when I come home, and load it up before I go to bed. I don't reload before I leave for the day, but 99% of the time when I get home later that afternoon, I still have a decent amount of hot coals/ash in the stove to get another fire going quickly.
At times I do miss the top-load feature I had on my VC Encore 1450. I also wish this stove had andirons to keep the load from shifting against the front of the glass -- also has caught me once or twice, when, opening the door, i've had the wood shift forward and fortunately, I haven't had a log roll out into the house (yet).
Its definitely a different beast than my VC stove and has taken some time to get to know... just like a woman, you have to learn its sweet spots and how to massage it to get maximum output
