If you are referring to the flue located at the bottom of the burner, it is used to control how much air is fed to the flame. The more air that that you allow to enter (i.e. uncovering the opening) the higher the flame will get and vice versa.

∙ 15y agoThe barrel is the long bit coming out from the base of the burner that the gas travels up. Down the bottom of the barrel, there is this little knob that you spin around. This controls the amount of air that goes up the barrel. If you cover up the holes, this makes the flame yellow, which means the gas isn't to its full power and heat level, because the gas needs oxygen to stay alight. When you un-cover the holes, the flame goes blue. This is harder to see. WHen the holes are un-covered, the gas flame is to its full power and heat level because it has the maximum amount of oxygen coming to it.
