Delavan 00800-80a7 Oil Burner Nozzle 8.00 Gph 80 Degree

Product Description

The DELAVAN 00800-80a7 is a Type A hollow-cone oil burner nozzle rated at 8.00 gallons per hour (GPH) with an 80-degree spray angle. It features a brass body and steel orifice disc, and operates at a rated pressure of 100 psi. Droplet distribution is concentrated on the outer edge of the cone, which promotes reliable ignition and low-noise combustion. This nozzle is designed for residential oil-fired heating equipment and is manufactured under ISO 9001 quality standards. HVAC and oil burner service technicians install this nozzle as part of routine burner maintenance and combustion tuning.

The 00800-80a7 is suited for residential oil burner applications where a hollow-cone air pattern is required. The Type A hollow-cone design is typically used on burners with matching hollow-cone air patterns and is appropriate for throughputs up to 2.00 GPH in standard service, with this nozzle rated at 8.00 GPH for higher-demand residential systems. A sintered filter is integrated into the nozzle to help protect the orifice from fuel contaminants. This nozzle is a common replacement component during annual oil burner tune-ups.

Key Features

• Type A hollow-cone spray pattern concentrates droplets at the outer edge of the cone for stable ignition
• 8.00 GPH flow rate at rated operating pressure
• 80-degree spray angle for compatibility with hollow-cone air pattern burners
• Brass body with steel orifice disc for durability in fuel oil service
• Integrated sintered filter helps protect the orifice from particulate contamination
• Manufactured to ISO 9001 quality standards

Compatibility

Designed as an OEM-style replacement nozzle for residential oil-fired burners requiring a Type A hollow-cone spray pattern at 8.00 GPH and an 80-degree spray angle.

Installation Notes

Oil burner nozzle replacement is typically performed by a licensed HVAC technician or oil burner service professional. Always shut down the burner and allow the system to cool before removing the existing nozzle. Use a proper nozzle wrench to avoid damaging the nozzle adapter, and verify that fuel supply pressure matches the rated operating pressure before firing the burner. Follow applicable local codes and manufacturer service guidelines when performing combustion system maintenance.
