The german market westfalias are equipped with a "flame sensor" which shuts
off the gas to the burner if no flame is present.  Just like on your natural
gas house furnace or water heater. The German TUV requires this safety
feature. It makes the stove harder to light because you have to heat up the
thermocouple before the stove will stay on by itself.
