Choosing and fitting

When selecting a replacement oil nozzle of this type, three key parameters must match the burner's data plate: flow rate (in GPH), spray angle, and spray pattern (hollow, solid, or semi-solid). The thread size is standard for this nozzle type, but verify compatibility with the burner's nozzle adapter before installation. Always check the original part number or the burner manufacturer's specification to ensure the exact rating, angle, and pattern are correct.

Signs of failure

Oil nozzles of this kind can fail due to clogging, wear, or improper installation, leading to incomplete combustion. Symptoms include sooting, flame pulsation, unstable ignition, or increased fuel consumption. Regular inspection and replacement of the nozzle are necessary to maintain efficient burner operation.
