Choosing and fitting

Oil nozzles are selected by flow rate, spray angle, and nozzle type to match the burner's design specifications. The 0.4 GPH capacity, 45° angle, and Type B pattern must correspond to the equipment's requirements. Replacement nozzles must be ordered with the correct SKU or article number to ensure proper fit and performance.
