Ah, brings me back to the bad ol' days of single wide livin' with a wood stove. Skipping across the linoleum floor with as few steps as possible to get the fire goin' Later we got fancy with indoor/outdoor carpet and a kerosene heater. As long as it didn't run out, I only had to turn it up because it stayed lit. There was no ventilation, per se, but those old hand crank windows never did exactly close tightly.

So, people don't use kerosene heaters anymore? If it isn't vented, where does the moisture go? I have a propane heater for my winter camping tent. It's got a flue pipe out the roof. The tank stays outside with a line run in.
