Delavan 01200-70A7 Hollow Cone Nozzle 12.00 Gph 70 Degree

Product Description

The DELAVAN 01200-70A7 is a hollow cone oil burner nozzle rated at 12.00 gallons per hour (GPH) with a 70-degree spray angle. It is designed to atomize fuel oil into a fine, evenly distributed hollow cone pattern that supports stable ignition and efficient combustion in residential and light commercial oil-fired heating equipment. The unit ships with a mesh strainer, which filters particulates before they reach the nozzle orifice. Licensed oil burner technicians and HVAC service professionals install and service this component during routine maintenance or combustion tune-ups.

This nozzle is suited for oil-fired forced-air furnaces, boilers, and water heaters that require a 12.00 GPH flow rate at a 70-degree hollow cone spray pattern. The hollow cone pattern is commonly specified for pressure-atomizing gun-type burners where a well-defined flame shape is required for proper heat exchanger performance. Always verify the burner manufacturer's nozzle specification sheet before selecting a replacement to confirm GPH, spray angle, and spray pattern type.

Key Features

• 12.00 GPH flow rate for medium-to-high output oil burner applications
• 70-degree spray angle produces a wide, hollow cone atomization pattern
• Hollow cone pattern supports stable flame geometry in gun-type pressure-atomizing burners
• Integrated mesh strainer helps prevent orifice fouling from fuel contaminants
• Direct replacement form factor for standard oil burner nozzle ports

Compatibility

Designed as an OEM-style replacement nozzle for oil-fired residential and light commercial heating equipment requiring a 12.00 GPH, 70-degree hollow cone nozzle. Confirm compatibility against the original equipment nozzle specification before installation.

Installation Notes

Installation should be performed by a licensed oil burner technician or qualified HVAC service professional. Shut off the burner and allow the system to cool before removing the existing nozzle. Use a proper nozzle wrench to avoid damaging the nozzle adapter or electrode assembly. After installation, perform a combustion analysis to verify CO2, draft, and smoke number are within acceptable limits per NFPA 31 guidelines.
