<P> To set the heat output of the burner , the rate of fuel delivery via the nozzle must be adjustable . This is often achieved by an adjustable pressure relief valve between the pump and the nozzle . When the set pressure is reached ( usually 100psi ) , this valve opens and allows excess oil to flow through a bypass back to the fuel tank or the pump suction side . </P>
