Choosing and fitting

Oil nozzles of this type are selected based on the required flow rate (in GPH), spray angle, and spray pattern (hollow or solid) to match the burner's specifications. The nozzle must be compatible with the burner's fuel pump pressure and the desired combustion characteristics. When installing, ensure the nozzle is clean and properly seated, and use a torque wrench to tighten to the manufacturer's recommended specification. Always compare the nozzle's markings with the old one before fitting.

Signs of failure

When oil nozzles of this kind fail or become clogged, the burner may produce an uneven flame, soot, or fail to ignite. The equipment might exhibit reduced heating efficiency or frequent shutdowns. Check the nozzle for blockages or wear, and inspect the spray pattern for irregularities. If the nozzle is damaged or blocked, replace it with a new one of the same specifications.
