Its kerosene, not gas, but I thought this was closest to the topic. This kerosene stove has a bucket with a plunger that you up end and kerosene flows down the tube into the bottom. there are two baffles in the bottom. I didn't take note if it mattered how they were put in when I removed them. This is a pic inside where the kerosene burns and the baffles sit. Is anyone familiar with this stove?
