Delavan 00700-70A7 Oil Burner Nozzle 7.00 Gph 70 Degree

Product Description

The DELAVAN 00700-70A7 is a Type A hollow-cone oil burner nozzle rated at 7.00 gallons per hour (GPH) with a 70-degree spray angle. It atomizes fuel oil into a fine hollow-cone spray pattern, concentrating droplet distribution along the outer edge of the cone. This design promotes reliable ignition and low-noise combustion. The nozzle is built with a brass body and steel orifice disc, rated for operation at 100 psi and up to 80 degrees F. It includes a sintered filter to help protect the orifice from debris. Licensed oil burner technicians install this nozzle as part of routine service on residential heating equipment.

Type A hollow-cone nozzles are suited for burners that produce a hollow-cone air pattern and are typically used for fuel throughputs up to 2.00 GPH at lower flow demands, with this unit serving higher-volume residential applications at 7.00 GPH. The nozzle fits standard residential oil burner assemblies and is selected during annual tune-ups or combustion troubleshooting when the existing nozzle shows wear, clogging, or off-spec spray pattern. Proper nozzle sizing is determined by the burner manufacturer's specifications and the system's fuel delivery pressure.

Key Features

• Type A hollow-cone spray pattern concentrates droplets at the cone perimeter for good ignition characteristics
• 7.00 GPH flow rate at 100 psi operating pressure
• 70-degree spray angle matches burner air-pattern requirements
• Brass body with steel orifice disc for durability in fuel oil service
• Sintered filter element helps keep the orifice free of particulate contamination
• Manufactured under ISO 9001 quality standards

Compatibility

Designed as an OEM-style replacement nozzle for residential oil-fired burner assemblies requiring a Type A hollow-cone nozzle at 7.00 GPH and a 70-degree spray angle.

Installation Notes

Oil burner nozzle replacement is performed by a licensed oil burner technician. Shut off the fuel supply and power to the burner before beginning service, and allow the combustion chamber to cool completely. Use a proper nozzle wrench to remove and install the nozzle without stressing the nozzle adapter or fuel line. After installation, verify combustion performance with appropriate test equipment per applicable service codes before returning the unit to operation.
