Choosing and fitting

When selecting a replacement oil nozzle of this type, ensure the capacity (in gallons per hour), spray angle, and nozzle type match the burner's requirements. The nozzle's flow rate must be compatible with the burner's operating range. Installation involves removing the old nozzle and fitting the new one securely, ensuring proper alignment and sealing.

Signs of failure

Common failure modes for oil nozzles include clogging, which can cause uneven spray patterns, reduced combustion efficiency, or difficulty igniting. A worn or damaged nozzle may lead to soot buildup, increased fuel consumption, or burner shutdown. Regular inspection and cleaning or replacement are recommended to maintain proper operation.
