Delavan 01000-45a7 Oil Burner Nozzle 10.00 Gph 45 Degree

Product Description

The DELAVAN 01000-45a7 is a hollow-cone Type A oil burner nozzle rated at 10.00 GPH and a 45-degree spray angle. It is designed for residential oil-fired heating systems where the burner air pattern calls for a hollow-cone spray. The nozzle body is constructed of brass with a steel orifice disc, and it incorporates a sintered filter element. Droplet distribution is concentrated on the outer edge of the cone, which promotes reliable ignition and low-noise combustion at flow rates through the nozzle up to 10.00 GPH at a rated pressure of 100 psi. Licensed oil burner technicians and HVAC service professionals are the primary installers of this component.

This nozzle is suited for residential oil burner applications where a hollow-cone air pattern is specified. Hollow-cone Type A nozzles are the standard choice for burners with lower throughput requirements and are commonly found in residential warm-air furnaces, boilers, and water heaters fired by No. 2 fuel oil. The 45-degree spray angle matches burner heads that require a tighter, more focused cone geometry. Always verify the spray angle, flow rate, and cone type called out on the burner manufacturer's nozzle specification plate before installation.

Key Features

• Hollow-cone Type A spray pattern concentrates droplets at the outer edge of the cone for stable, low-noise combustion
• 10.00 GPH flow rate at 100 psi operating pressure
• 45-degree spray angle matches compatible hollow-cone burner head configurations
• Brass body with steel orifice disc for durability in fuel oil service
• Integrated sintered filter element helps protect the orifice from particulate contamination
• Manufactured under ISO 9001 quality standard

Compatibility

Designed as an OEM-style replacement nozzle for residential oil burners specifying a hollow-cone Type A nozzle at 10.00 GPH and a 45-degree spray angle. Confirm spray angle, flow rate, and cone type against the burner nameplate or service manual before ordering.

Installation Notes

Oil burner nozzle replacement is performed by licensed oil burner technicians or qualified HVAC service professionals. Shut down the burner and allow the system to cool before accessing the nozzle assembly. Use an appropriate nozzle wrench to avoid distorting the nozzle body or damaging the electrodes and igniter assembly. After installation, verify combustion quality with a flue gas analyzer per standard industry practice before returning the system to service.
