Function of the wheel

Customer (PF13L160EI): 

I just start to use the power burner. It is great! There is a question I like to ask: What is the function of the wheel toward the burner inlet and when to use it?


Great!  The wheel is to control the fuel/air mixture.   Usually turning it away from the burner gives stronger flame however may not full circle of flame from the burner.   Optimal is to have full circle of flame while it is still strong enough.
