Delavan 00250-90w7 Oil Burner Nozzle 2.50 Gph 90 Degree

Product Description

The DELAVAN 00250-90w7 is a Type W all-purpose oil burner nozzle rated at 2.50 gallons per hour (GPH) with a 90-degree spray angle. Built with a brass body and steel orifice disc, this nozzle delivers a semi-hollow spray pattern that falls between a true hollow cone and a solid cone. It is suitable for use at flow rates from 0.40 to 8.00 GPH regardless of the burner air pattern, making it a versatile choice for residential oil-fired heating equipment. Lower flow rates through this nozzle tend to produce a more hollow cone pattern. Licensed HVAC technicians and oil burner service professionals install this nozzle during routine maintenance, nozzle replacement, and combustion tune-ups.

This nozzle is designed for residential oil burner applications. The Type W all-purpose spray pattern is compatible with a wide range of burner air patterns, allowing it to substitute for hollow or solid cone nozzles in many installations operating between 0.40 and 8.00 GPH. It is rated for operation at 100 psi and a temperature rating of 80 degrees F. A sintered filter is integrated into the nozzle assembly to help protect the orifice disc from particulate contamination during operation.

Key Features

• Type W all-purpose spray pattern — usable in place of hollow or solid cone nozzles across a wide GPH range
• 2.50 GPH flow rate at rated operating pressure
• 90-degree spray angle for broad flame coverage
• Brass body with steel orifice disc for durability in oil service
• Integrated sintered filter to protect the orifice from debris

Compatibility

Designed as an OEM-style replacement nozzle for residential oil-fired burner systems requiring a 2.50 GPH, 90-degree, Type W all-purpose nozzle at 100 psi operating pressure.

Installation Notes

Oil burner nozzle replacement is performed by licensed oil burner technicians or qualified HVAC service professionals. Shut down the burner and allow the combustion chamber to cool before beginning service. Use a nozzle wrench to remove and install the nozzle to avoid damage to the adapter or nozzle body. After installation, verify combustion performance with appropriate test instruments before returning the system to service.
