Delavan 2.75-90-B Oil Burner Nozzle 2.75 Gph 90 Degree

Product Description

The DELAVAN 2.75-90-B is a solid cone Type B oil burner nozzle rated at 2.75 GPH and designed for operation at 100 psi. It atomizes fuel oil into a uniform droplet distribution across the full spray pattern at a 90-degree angle. The solid cone pattern delivers consistent coverage that supports smooth ignition and efficient combustion, making it well suited for larger residential and light commercial oil-fired burners. Licensed oil burner technicians and HVAC service professionals are the primary installers of this component.

This nozzle is used in oil-fired heating appliances where a solid cone spray pattern is specified. The Type B designation produces droplets distributed fairly uniformly throughout the complete pattern. At flow rates above 8.00 GPH the spray pattern becomes progressively more hollow, so this nozzle is best applied at or below that threshold. It is a common service replacement in residential oil furnaces, boilers, and water heaters that call for a solid cone nozzle at a 90-degree spray angle.

Key Features

• 2.75 GPH flow rate at 100 psi operating pressure
• 90-degree spray angle for wide pattern coverage
• Solid cone Type B pattern distributes droplets uniformly across the full spray zone
• Supports smooth ignition and efficient combustion, particularly in larger burners
• Blue vial color coding for quick field identification of spray angle

Compatibility

Designed as an OEM-style replacement nozzle for oil burner appliances specifying a 2.75 GPH solid cone Type B nozzle at a 90-degree spray angle and 100 psi operating pressure.

Installation Notes

Oil burner nozzle replacement is performed by licensed oil burner technicians or qualified HVAC service professionals. Shut down the burner and allow the system to cool completely before servicing the nozzle assembly. Use an appropriate nozzle wrench to avoid damaging the nozzle body or electrode assembly, and verify that the replacement nozzle matches the GPH rating, spray angle, and pattern type specified on the appliance data plate. Follow all applicable local codes and the appliance manufacturer service instructions when setting electrodes after nozzle replacement.
