I was thinking of replacing the all-night at the grandparents house with one of these bad boys. Any install one, sell one, or use one? Any comments? I'm concerned it may not fit with the existing chimney system because the current all nighter vents right out of the back of the stove into the thimble, through the wall into a tee and then up the exterior of the house. Certainly a poor drafting situation. I may have to redo the chimney system with a purely vertical setup. But regardless of that, what's the general concensus on this stove? I really like the looks and the flash fire system seems kinda neat.
