Delavan 1.75-60-A Oil Burner Nozzle 1.75 Gph 60 Degree

Product Description

The DELAVAN 1.75-60-A is a hollow cone oil burner nozzle rated at 1.75 gallons per hour (GPH) with a 60-degree spray angle, designed for operation at 100 psi. It is used in residential and light commercial oil-fired heating systems to atomize fuel oil before ignition. The Type A hollow cone pattern concentrates droplet distribution along the outer edge of the spray cone, which promotes reliable ignition and low-noise combustion. HVAC technicians and oil burner service professionals install this nozzle as a routine maintenance or service replacement item. The red vial identifies the 1.75 GPH flow rate for quick identification in the field.

This nozzle is suited for oil burners that produce a hollow cone air pattern and handle throughputs up to 2.00 GPH. The Type A designation makes it appropriate for burners specifically matched to hollow cone atomization. It is commonly installed in forced-air oil furnaces and oil-fired boilers found in residential and light commercial heating applications. Always match the nozzle GPH rating, spray angle, and cone type to the burner manufacturer's specification when selecting a replacement.

Key Features

• 60-degree spray angle for proper flame geometry in matched burner heads
• Hollow cone Type A pattern concentrates droplets at the outer cone edge
• Supports throughputs up to 2.00 GPH
• Promotes good ignition characteristics and low-noise combustion
• Red vial color-coding allows fast GPH identification during service

Compatibility

Designed as an OEM-style replacement nozzle for oil burners requiring a hollow cone Type A spray pattern with a 1.75 GPH rating and 60-degree spray angle at 100 psi.

Installation Notes

Oil burner nozzles are installed by qualified HVAC technicians or oil burner service professionals. Shut off power to the burner and close the fuel supply valve before replacing the nozzle. Use the correct nozzle wrench to avoid damaging the nozzle body or electrode assembly, and inspect the electrodes and igniter for wear during the same service visit. Always verify the replacement nozzle matches the burner manufacturer's specified GPH rating, spray angle, and cone type before firing the system.
