Hi, I installed a new Harman P38 Control board and can not find any explanation on the Potentiometer on the back (P3).

In Center of the Board it shows P3 (On Back Of Board), does anyone know what this is for?
 
That must be the pot for, draft adjustment he made a 10 volt change on the motor
combustion
 
What would happen if it is not adjusted correctly?
 
If the draft is in specs from the manufacturer it is ok if it is better to adjust it.
if you fire down too much draft the stove going to work well, but still going to be less effective
