Delavan 00800-70B7 Oil Burner Nozzle 8.00 Gph 70 Degree

Product Description

The DELAVAN 00800-70B7 is a Solid Cone Type B oil burner nozzle rated at 8.00 gallons per hour (GPH) with a 70-degree spray angle. It is designed for residential oil-fired heating systems where consistent atomization and reliable ignition are essential. The solid cone spray pattern distributes droplets uniformly throughout the full pattern at this flow rate, supporting smooth ignition and efficient combustion in larger residential burners. The brass body and steel orifice disc provide durable construction suited to continuous service in oil burner assemblies. A sintered filter element is integrated into the nozzle assembly to protect the orifice from particulate contamination.

This nozzle is intended for residential oil-fired heating applications, including forced-air furnaces and boilers that use pressure-atomizing gun-type burners. The solid cone pattern is particularly effective in larger burners where uniform droplet distribution across the full spray zone improves combustion quality. At flow rates above 8.00 GPH, the spray pattern becomes progressively more hollow, so proper sizing to the burner and appliance is important. This nozzle is installed during routine oil burner service calls and annual tune-ups by licensed oil burner technicians.

Key Features

• Solid Cone Type B spray pattern delivers uniform droplet distribution throughout the full cone at rated flow
• 8.00 GPH flow rate rated at 100 psi operating pressure
• 70-degree spray angle suited to larger residential oil burner combustion chambers
• Brass body with steel orifice disc for corrosion resistance and durability
• Integrated sintered filter protects the orifice from particulate contamination
• Meets ISO 9001 applicable standard

Compatibility

Designed as an OEM-style replacement nozzle for residential pressure-atomizing oil burners requiring a Type B solid cone nozzle at 8.00 GPH and 70-degree spray angle.

Installation Notes

Oil burner nozzle replacement is performed by licensed oil burner technicians as part of routine annual service or combustion troubleshooting. Always shut down the burner and allow the oil supply line to depressurize before removing the nozzle. Use a proper nozzle wrench to avoid damaging the nozzle adapter or electrodes during removal and installation. Verify that the replacement nozzle GPH rating, spray angle, and spray pattern type match the appliance manufacturer specifications before firing the burner.
