Choosing and fitting

When selecting a replacement oil nozzle of this type, ensure the capacity, spray angle, and spray pattern match the burner's requirements. The nozzle must be compatible with the burner's fuel pump pressure and the desired firing rate. Installation involves removing the old nozzle and installing the new one with the correct torque, ensuring the O-ring or gasket is in place to prevent leaks.

Signs of failure

Common failure modes for oil nozzles include clogging due to debris or carbon buildup, which can cause uneven flame, soot formation, or incomplete combustion. A worn or damaged nozzle may lead to poor atomization, resulting in a yellow flame, increased fuel consumption, or burner shutdown. Regular inspection and cleaning or replacement are necessary to maintain proper burner operation.
