Delavan 00800-90B7 Oil Burner Nozzle 8 Gph 90 Degree

Product Description

The DELAVAN 00800-90B7 is a solid cone Type B oil burner nozzle rated at 8 GPH and designed for residential oil-fired heating systems. It atomizes fuel oil into a uniform spray pattern across the full cone, supporting smooth ignition and consistent combustion. The brass body and steel orifice disc provide durability in demanding burner environments. A built-in Monel strainer filters debris before it reaches the orifice. Rated at 100 psi operating pressure, this nozzle is installed by HVAC and oil burner service technicians as part of routine annual burner maintenance or when replacing a fouled or worn nozzle.

This nozzle is suited for residential oil burners where a full, uniform spray distribution is required. The solid cone pattern delivers droplets throughout the complete spray area, making it particularly effective in larger residential burners where thorough fuel distribution supports efficient combustion. At flow rates above 8 GPH, the spray pattern can transition toward a more hollow profile, so this nozzle is best applied at or below its rated flow rate. It installs in standard oil burner nozzle adapters and is compatible with No. 1 and No. 2 fuel oil.

Key Features

• Solid cone Type B spray pattern distributes droplets uniformly throughout the full spray area
• 8 GPH flow rate rated at 100 psi operating pressure
• 90-degree spray angle for broad pattern coverage in residential burner applications
• Brass body and steel orifice disc construction for corrosion resistance and durability
• Monel strainer filters fuel before it reaches the orifice, reducing fouling risk
• Manufactured under ISO 9001 quality standards

Compatibility

Designed as an OEM-style replacement nozzle for residential oil-fired burner systems requiring a solid cone Type B nozzle at an 8 GPH flow rate and 90-degree spray angle.

Installation Notes

Oil burner nozzles are replaced by qualified HVAC or oil burner service technicians, typically during annual tune-up service. Always shut down the burner and allow the combustion chamber to cool before removing the nozzle. Use a proper nozzle wrench to avoid damaging the adapter or electrode assembly. Handle nozzles carefully and avoid touching the orifice disc, as contamination or physical damage will affect spray pattern and combustion performance.
