This nozzle includes a fuel supply adjustment mechanism, enabling adaptation to changing operating conditions. It is designed for larger burners, providing smooth ignition and efficient combustion. The product is also referenced under article numbers 3042208 and 345.892.110.

Oil nozzles of this type are selected based on capacity, spray angle, and spray pattern to match the burner's requirements. When replacing, ensure the nozzle's capacity and angle correspond to the burner's specifications. The nozzle is typically threaded and should be installed with the appropriate gasket or seal. Always compare the old nozzle's markings with the new one before fitting.

When oil nozzles of this kind fail, symptoms may include poor ignition, uneven flame, or soot buildup. The burner may struggle to start or produce a smoky exhaust. Check the nozzle for clogging or wear, and verify that the spray pattern is consistent. If the nozzle is damaged or blocked, it should be replaced.
