Delavan 00650-80a7 Oil Burner Nozzle 6.50 Gph 80 Degree

Product Description

The DELAVAN 00650-80a7 is an oil burner nozzle rated at 6.50 gallons per hour (GPH) with an 80-degree hollow cone spray pattern. It meters and atomizes fuel oil into the combustion chamber of a pressure-fired oil burner, producing a finely divided spray that supports clean, efficient ignition. The hollow cone pattern distributes fuel along the outer edge of the spray envelope, which suits specific burner head geometries and combustion chamber configurations. Licensed oil burner technicians install and replace this nozzle as part of routine annual service or combustion tune-up procedures. It weighs 0.10 pounds.

This nozzle is used in residential and light commercial oil-fired heating equipment, including forced-air oil furnaces, oil boilers, and hydronic heating systems equipped with pressure-fired gun-type burners. It is selected when the burner manufacturer or service manual specifies a 6.50 GPH, 80-degree hollow cone nozzle for proper combustion performance. Annual nozzle replacement is standard practice in oil heat service regardless of visible wear.

Key Features

• 6.50 GPH flow rate for precise fuel metering at rated burner pump pressure
• 80-degree spray angle matches burner head and combustion chamber geometry requirements
• Hollow cone atomization pattern concentrates fuel at the outer spray perimeter
• Lightweight at 0.10 pounds for easy field handling and storage
• Standard nozzle form factor compatible with common oil burner nozzle adapters

Compatibility

Designed as an OEM-style replacement nozzle for pressure-fired gun-type oil burners specifying a 6.50 GPH, 80-degree hollow cone nozzle. Consult the burner manufacturer service manual to confirm the correct flow rate, angle, and spray pattern before installation.

Installation Notes

Oil burner nozzle replacement is performed by a licensed oil burner technician or qualified HVAC-oil service professional. Shut down the burner and allow the system to cool before opening the nozzle adapter. Use a proper nozzle wrench to remove and seat the nozzle without damaging the electrode assembly or nozzle adapter threads. After installation, verify combustion performance with a flue gas analyzer per applicable codes and the equipment manufacturer's service instructions.
