Delavan Oil nozzle 00250-45W7

The Delavan Oil nozzle 00250-45W7 is a component used in oil burners to atomize fuel for combustion. It has a capacity of 2.5 gallons per hour (GPH) and a spray angle of 45 degrees. The spray pattern is designated as 'W', which is an all-purpose type that can be used in place of solid or hollow cone nozzles. This nozzle is compatible with flow rates ranging from 0.40 to 8.00 GPH.

When selecting a replacement oil nozzle, ensure the capacity (GPH), spray angle, and spray pattern match the burner's requirements. The nozzle must be compatible with the burner's flow rate range. Installation involves removing the old nozzle and installing the new one, ensuring proper torque and alignment.

A failing oil nozzle may cause incomplete combustion, leading to soot buildup or increased emissions. Symptoms include uneven flame, poor ignition, or reduced burner efficiency. Check the nozzle for clogging or wear, and replace if necessary.
