Delavan 5.00-80-A Oil Burner Nozzle 5 Gph 80 Degree

Product Description

The DELAVAN 5.00-80-A is a hollow cone oil burner nozzle rated at 5.00 gallons per hour (GPH) with an 80-degree spray angle, designed for operation at 100 psi. It produces a hollow cone spray pattern, meaning droplet distribution concentrates on the outer edge of the cone. This geometry supports reliable ignition and low-noise combustion in residential and light commercial oil-fired heating equipment. The nozzle is identified by a red vial and is installed by licensed oil burner technicians as part of routine annual service or combustion tune-ups.

The 5.00-80-A is suited for oil burners that use a hollow cone air pattern. Type A hollow cone nozzles are primarily applied on burners designed to match that air pattern, and are well suited for fuel throughputs up to 2.00 GPH in lower-output applications. At 5.00 GPH, this nozzle serves mid-range firing rate applications in forced-air oil furnaces, boilers, and water heaters where an 80-degree hollow cone spray geometry matches the combustion head configuration.

Key Features

• 5.00 GPH firing rate at 100 psi operating pressure
• 80-degree spray angle for wide combustion chamber coverage
• Hollow cone spray pattern concentrates droplets on the outer cone edge
• Supports good ignition characteristics and low-noise combustion
• Red vial identification for quick nozzle-type verification in the field
• Type A classification matched to burners with hollow cone air patterns

Compatibility

Designed as an OEM-style replacement nozzle for oil burners requiring a hollow cone Type A nozzle at a 5.00 GPH firing rate and 80-degree spray angle.

Installation Notes

Oil burner nozzles are replaced by qualified oil burner technicians, typically during annual service. Always shut off the fuel supply and disconnect power to the burner before removing the nozzle assembly. Use a proper nozzle wrench to avoid damaging the nozzle adapter or electrodes. Verify that the replacement nozzle GPH rating, spray angle, and spray pattern type match the burner manufacturer specifications before firing.
