Some of the videos are redundant and a bit long-winded. I still haven't figured out when I should turn off or open the air supply. My stove only has one regulator and there is no flame when the air supply is reduced. There doesn't seem to be any secondary air. Also, lighting from above does not always work. I also don't understand why you shouldn't add pine cones, for example, when lighting the stove. It burns much better and doesn't always go out. If you only light it from the top, the fire goes out every now and then, which causes a lot of smoke, which also enters the room when you open the oven door. The theory is good, but it doesn't always work in practice.
