It atomizes fuel oil into a uniform droplet distribution across the full spray pattern at a 90-degree angle. The solid cone pattern delivers consistent coverage that supports smooth ignition and efficient combustion, making it well suited for larger residential and light commercial oil-fired burners. Licensed oil burner technicians and HVAC service professionals are the primary installers of this component.\u003c\/p\u003e\u003cp\u003eThis nozzle is used in oil-fired heating appliances where a solid cone spray pattern is specified. The Type B designation produces droplets distributed fairly uniformly throughout the complete pattern. At flow rates above 8.00 GPH the spray pattern becomes progressively more hollow, so this nozzle is best applied at or below that threshold. It is a common service replacement in residential oil furnaces, boilers, and water heaters that call for a solid cone nozzle at a 90-degree spray angle.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e2.75 GPH flow rate at 100 psi operating pressure\u003c\/li\u003e\n\u003cli\u003e90-degree spray angle for wide pattern coverage\u003c\/li\u003e\n\u003cli\u003eSolid cone Type B pattern distributes droplets uniformly across the full spray zone\u003c\/li\u003e\n\u003cli\u003eSupports smooth ignition and efficient combustion, particularly in larger burners\u003c\/li\u003e\n\u003cli\u003eBlue vial color coding for quick field identification of spray angle\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement nozzle for oil burner appliances specifying a 2.75 GPH solid cone Type B nozzle at a 90-degree spray angle and 100 psi operating pressure.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eOil burner nozzle replacement is performed by licensed oil burner technicians or qualified HVAC service professionals. Shut down the burner and allow the system to cool completely before servicing the nozzle assembly. Use an appropriate nozzle wrench to avoid damaging the nozzle body or electrode assembly, and verify that the replacement nozzle matches the GPH rating, spray angle, and pattern type specified on the appliance data plate. Follow all applicable local codes and the appliance manufacturer service instructions when setting electrodes after nozzle replacement.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlow Rate\u003c\/strong\u003e: 2.75 GPH\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpray Angle\u003c\/strong\u003e: 90 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOperating Pressure\u003c\/strong\u003e: 100 psi\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpray Pattern\u003c\/strong\u003e: Solid Cone\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNozzle Type\u003c\/strong\u003e: Type B\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVial Color\u003c\/strong\u003e: Blue\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Oil Burner\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 2.75-90-B\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DELAVAN","offers":[{"title":"Default Title","offer_id":51284045758770,"sku":"2.75-90-B","price":17.79,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/309277664.jpg?v=1781067099","url":"https:\/\/voomisupply.com\/products\/delavan-2-75-90-b-oil-burner-nozzle-2-75-gph-90-degree","provider":"Voomi Supply","version":"1.0","type":"link"}
