Delavan 2.75-70-B Oil Burner Nozzle 2.75 Gph 70 Degree

Product Description

The DELAVAN 2.75-70-B is a solid cone oil burner nozzle rated at 2.75 gallons per hour (GPH) with a 70-degree spray angle, designed for use at 100 psi operating pressure. The Type B solid cone pattern distributes droplets uniformly throughout the complete spray pattern, making it well suited for smooth ignition and efficient combustion in residential and light commercial oil-fired heating equipment. Licensed HVAC technicians and oil burner service professionals install this nozzle as a direct service replacement during routine maintenance or combustion tune-ups.

This nozzle is used in oil burner assemblies where a solid cone spray pattern is specified. The Type B designation indicates a solid cone configuration, which performs consistently at lower flow rates and provides a progressively more hollow pattern at flow rates above 8.00 GPH. It is a standard choice for larger oil burners where uniform atomization across the full spray pattern supports stable flame characteristics and clean combustion.

Key Features

• 2.75 GPH flow rate at 100 psi operating pressure
• 70-degree spray angle for wide pattern coverage
• Solid cone Type B pattern distributes droplets uniformly throughout the spray
• Blue vial identification for quick field recognition
• Supports smooth ignition and efficient combustion in larger oil burners
• Pattern becomes progressively more hollow above 8.00 GPH, consistent with Type B behavior

Compatibility

Designed as an OEM-style replacement nozzle for oil burner assemblies requiring a 2.75 GPH, 70-degree, solid cone Type B nozzle at 100 psi.

Installation Notes

Oil burner nozzle replacement is performed by licensed HVAC technicians or oil burner service professionals. Shut down the burner and allow the system to cool before removing the nozzle assembly. Use the correct nozzle wrench to avoid damaging the nozzle adapter or electrodes. Always verify the replacement nozzle matches the original specifications for GPH, spray angle, and cone type before firing the system.
