Delavan 2.75-80-A Oil Burner Nozzle 2.75 Gph 80 Degree

Product Description

The DELAVAN 2.75-80-A is a hollow cone oil burner nozzle rated at 2.75 gallons per hour (GPH) with an 80-degree spray angle and a 100 psi operating pressure. It ships with a red vial for identification. Hollow cone Type A nozzles concentrate droplet distribution on the outer edge of the spray cone, which promotes reliable ignition and low-noise combustion. This nozzle is designed for oil-fired burner applications where a hollow cone air pattern is required, and it is particularly suited for fuel throughputs up to 2.00 GPH in standard residential and light commercial heating equipment.

This nozzle is installed in oil-fired heating systems including residential oil furnaces, oil boilers, and oil-fired water heaters. The hollow cone spray pattern matches burner heads that rely on an annular air distribution pattern. Licensed oil burner technicians and HVAC service professionals handle installation and replacement during seasonal tune-ups, nozzle changeovers, or combustion efficiency calls. The red vial designation assists with quick field identification when sorting nozzles by flow rate and spray angle.

Key Features

• 2.75 GPH flow rate for consistent fuel delivery at rated pressure
• 80-degree spray angle for wide hollow cone pattern
• Rated at 100 psi operating pressure
• Hollow cone Type A spray pattern concentrates droplets on the outer cone for stable ignition
• Low-noise combustion characteristics suited to residential installations
• Red vial for fast field identification by flow rate

Compatibility

Designed as an OEM-style replacement nozzle for oil burners that require a hollow cone spray pattern with a Type A designation, 80-degree angle, and 2.75 GPH flow rate at 100 psi.

Installation Notes

Oil burner nozzle replacement is performed by licensed oil burner technicians or qualified HVAC service professionals. Shut off the burner and allow the combustion chamber to cool before servicing. Use a proper nozzle wrench to remove and install the nozzle without distorting the nozzle body or adapter. After installation, verify combustion performance with a flue gas analyzer to confirm proper air-to-fuel ratio and smoke number per equipment manufacturer guidelines.
