A serious question about your stove, does the wood burn upright? I've never seen anything new like that. Also, how do you control air intake?
I figure you start a fire conventionally by building a fire on the floor with the front door open and lighting it.
Small to medium logs can be inserted via that door.
Once the fire's going - large logs can be fed from the top via a door in front of the chimney that opens there. I'm kinda amazed that the draw is such that smoke won't escape when that door is opened. Perhaps some does.
As far as air control goes, there's a manual lever on the bottom. There's also a little controller designed to be hooked to a thermostat - but it wasn't hooked up so I'm not at all convinced that's still working.
