Delavan 00650-70b7 Oil Burner Nozzle 6.5 Gph 70 Degree

Product Description

The DELAVAN 00650-70b7 is a Solid Cone Type B oil burner nozzle rated at 6.5 GPH flow rate and a 70-degree spray angle, designed for residential oil-fired heating systems. The Type B solid cone spray pattern distributes droplets uniformly throughout the full pattern at standard flow rates, supporting smooth ignition and consistent combustion. At flow rates above 8.00 GPH the pattern becomes progressively more hollow, so this nozzle is best matched to burners sized within its rated output. Construction features a brass body with a steel orifice disc and a Monel strainer for filtration at the inlet. Licensed HVAC technicians and oil burner service professionals install and service this component.

This nozzle is suited for residential oil burner applications operating at 100 psi and within a temperature rating of 80 degrees F. The solid cone spray pattern is particularly effective in larger residential burners where uniform droplet distribution across the full spray cone improves combustion efficiency and reduces sooting. It is a direct-fit nozzle replacement for service calls and annual tune-up work on residential oil-fired boilers and furnaces.

Key Features

• Type B solid cone spray pattern distributes droplets uniformly at rated flow rates up to 8.00 GPH
• 6.5 GPH flow rate at 100 psi operating pressure
• 70-degree spray angle for broader combustion chamber coverage
• Brass body with steel orifice disc for durability in oil service
• Monel strainer filters inlet fuel to protect the orifice disc
• Manufactured under ISO 9001 quality standards

Compatibility

Designed as an OEM-style replacement nozzle for residential oil-fired burners requiring a 6.5 GPH Type B solid cone nozzle at a 70-degree spray angle and 100 psi operating pressure.

Installation Notes

Oil burner nozzle replacement is performed by licensed HVAC technicians or qualified oil burner service professionals. Always shut off the fuel supply and de-energize the burner before removing the nozzle assembly. Use a proper nozzle wrench to avoid distorting the nozzle body or damaging the electrodes and nozzle adapter. After installation, verify fuel pressure at 100 psi and confirm ignition and combustion performance before returning the system to service.
