It is designed for residential oil-fired heating systems where consistent atomization and reliable ignition are required. The solid-cone spray pattern distributes droplets uniformly across the full spray pattern at standard flow rates. The body is constructed from brass with a steel orifice disc, and a Monel strainer filters fuel before it reaches the orifice. At flow rates above 8.00 GPH the pattern becomes progressively more hollow, but at 2.5 GPH this nozzle delivers stable, efficient combustion suited to smaller residential burner heads. Licensed oil burner technicians and HVAC service pros handle installation and replacement.\u003c\/p\u003e\n\u003cp\u003eThis nozzle is intended for residential oil burner applications operating at a rated pressure of 100 psi and a temperature rating of 80 degrees F. It is commonly installed in forced-air oil furnaces and oil boilers during annual tune-ups or when combustion analysis indicates an atomization issue. The 30-degree spray angle suits firebox geometries that require a tighter, more concentrated flame pattern. Proper nozzle selection by GPH, spray angle, and cone type is critical to achieving correct CO2 and smoke number readings during combustion analysis.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid-cone Type B spray pattern distributes droplets uniformly throughout the full pattern at 2.5 GPH\u003c\/li\u003e\n  \u003cli\u003eBrass body with steel orifice disc for durability in continuous fuel-oil service\u003c\/li\u003e\n  \u003cli\u003eMonel strainer filters incoming fuel to protect the orifice from particulate contamination\u003c\/li\u003e\n  \u003cli\u003e30-degree spray angle suited to tighter firebox geometries in residential burners\u003c\/li\u003e\n  \u003cli\u003eRated at 100 psi operating pressure and 80 degrees F temperature rating\u003c\/li\u003e\n  \u003cli\u003eManufactured under ISO 9001 quality standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement nozzle for residential oil burner systems requiring a 2.5 GPH, 30-degree, solid-cone Type B nozzle at 100 psi operating pressure.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eOil burner nozzle replacement is performed by licensed oil burner technicians or qualified HVAC service professionals. Always shut off power to the burner and close the fuel supply valve before removing the nozzle assembly. Use a proper nozzle wrench to avoid damaging the nozzle adapter or electrode assembly, and verify electrode gap settings have not shifted during service. Dispose of the used nozzle properly and confirm combustion performance with a flue gas analyzer after startup.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eProduct Type\u003c\/strong\u003e: Oil Burner Nozzle\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCone Type\u003c\/strong\u003e: Type B, Solid Cone\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlow Rate\u003c\/strong\u003e: 2.5 GPH\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpray Angle\u003c\/strong\u003e: 30 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePressure Rating\u003c\/strong\u003e: 100 psi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTemperature Rating\u003c\/strong\u003e: 80 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Material\u003c\/strong\u003e: Brass\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOrifice Disc Material\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFilter Type\u003c\/strong\u003e: Monel Strainer\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Residential\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplicable Standard\u003c\/strong\u003e: ISO 9001\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: DELAVAN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 00250-30B7\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DELAVAN","offers":[{"title":"Default Title","offer_id":51383710122290,"sku":"00250-30B7","price":17.48,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/312670677.jpg?v=1782605120","url":"https:\/\/voomisupply.com\/products\/delavan-00250-30b7-oil-burner-nozzle-2-5-gph-30-degree","provider":"Voomi Supply","version":"1.0","type":"link"}
