Choosing and fitting

When selecting a replacement oil nozzle, verify that the flow rate (GPH), spray angle, and spray pattern match the original specifications. The nozzle must be compatible with the burner's fuel pump pressure and the combustion chamber design. 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 dirt or debris, which can cause incomplete combustion, soot buildup, or a noisy flame. A worn or damaged nozzle may lead to improper fuel atomization, resulting in poor ignition, flame instability, or increased fuel consumption. Regular inspection and cleaning or replacement of the nozzle are recommended to maintain burner efficiency.
