Delavan 110-80a1 Oil Burner Nozzle 1.10 Gph 80 Degree

Product Description

The DELAVAN 110-80a1 is a Type A hollow cone oil burner nozzle rated at 1.10 gallons per hour (GPH) with an 80-degree spray angle. It atomizes fuel oil into a fine, hollow cone spray pattern for efficient combustion in residential and light commercial oil-fired heating equipment. The hollow cone pattern distributes fuel along the outer edges of the spray, which suits specific burner head geometries that require a defined flame shape. Licensed oil burner technicians and HVAC service pros are the typical installers of this component.

This nozzle is used in oil-fired forced-air furnaces, boilers, and water heaters where the burner assembly requires a 1.10 GPH flow rate and an 80-degree hollow cone pattern. The Type A designation refers to the nozzle's internal slot and strainer design, which influences atomization quality and spray consistency. It is suited for installations where the burner manufacturer specifies a hollow cone spray type at this flow rate and angle combination.

Key Features

• 1.10 GPH rated flow rate for precise fuel delivery
• 80-degree spray angle for wide combustion chamber coverage
• Type A hollow cone spray pattern distributes fuel along the spray periphery
• Designed for use with standard residential and light commercial oil burners
• Precision-machined orifice for consistent atomization and combustion efficiency

Compatibility

Designed as an OEM-style replacement nozzle for residential and light commercial oil-fired burner assemblies requiring a 1.10 GPH, 80-degree, Type A hollow cone nozzle specification.

Installation Notes

Oil burner nozzle replacement should be performed by a licensed oil burner technician or qualified HVAC service professional. Shut off the oil supply and de-energize the burner before beginning service. Always replace the nozzle with the exact GPH rating, spray angle, and spray pattern type specified by the burner manufacturer, as substituting an incorrect specification will affect combustion efficiency and safety. After installation, verify ignition and combustion quality with appropriate test instruments before returning the system to service.
