Each has to be regulated to match manufacturers specifications. Burners are not created exactly the same. Each requires fine adjustment.

Since the actual gas pressure right at the heating appliance can vary for several reasons (gas type, source pressure, piping distance, piping diameter), the job of the gas regulator includes not just "turning on" the gas when the thermostat calls for heat. The regulator must also deliver gas at the proper gas pressure specified by the manufacturer for the particular appliance.
