Delavan 00250-70w7 Oil Burner Nozzle 2.50 Gph 70 Degree

Product Description

The DELAVAN 00250-70w7 is a Type W all-purpose oil burner nozzle rated at 2.50 gallons per hour (GPH) with a 70-degree spray angle. Constructed with a brass body and steel orifice disc, it delivers a semi-hollow spray pattern that sits between a true hollow cone and a solid cone. The sintered filter helps protect the orifice from contaminants in the fuel supply. This nozzle is installed by licensed oil-burner technicians and HVAC service professionals during routine maintenance, nozzle replacement, or combustion tune-up procedures on residential heating equipment.

The 00250-70w7 is suited for residential oil-fired heating applications operating at a standard pressure rating of 100 psi and a temperature rating of 80 degrees F. The Type W spray pattern is versatile enough to substitute for solid or hollow cone nozzles across flow rates from 0.40 to 8.00 GPH, regardless of the burner air pattern. At lower flow rates within that range, the spray tends toward a more hollow cone distribution, giving technicians flexibility when selecting a replacement nozzle for a variety of residential oil burner configurations.

Key Features

• Type W all-purpose spray pattern usable in place of solid or hollow cone nozzles from 0.40 to 8.00 GPH
• 2.50 GPH flow rate at rated operating pressure
• 70-degree spray angle for broad flame coverage
• Brass body with steel orifice disc for durability in fuel oil service
• Sintered filter integrated to protect the orifice from particulate contamination
• Manufactured under ISO 9001 quality standards

Compatibility

Designed as an OEM-style replacement nozzle for residential oil-fired burner systems requiring a 2.50 GPH, 70-degree, Type W configuration.

Installation Notes

Oil burner nozzle replacement should be performed by a licensed oil-burner technician or qualified HVAC professional. Shut down the burner and allow the system to cool before accessing the nozzle assembly. Use a proper nozzle wrench to avoid damaging the nozzle body or adapter. After installation, verify combustion performance with a flue-gas analyzer per local code and equipment manufacturer guidelines.
