Identified by its blue vial, this nozzle atomizes fuel oil into a uniform droplet pattern across the full cone, supporting smooth ignition and efficient combustion. It is designed for installation in residential and light commercial oil-fired heating equipment. Licensed oil burner technicians and HVAC service professionals are the primary installers for this component.\u003c\/p\u003e\n\u003cp\u003eThis nozzle is suited for oil-fired furnaces, boilers, and water heaters that require a solid cone spray pattern at a 1.65 GPH firing rate. The Type B solid cone pattern distributes droplets consistently throughout the complete spray profile at lower flow rates. At flow rates above 8.00 GPH, the pattern becomes progressively more hollow, but at 1.65 GPH the full solid cone remains intact. This makes the nozzle particularly effective in larger burner applications where smooth, stable ignition is critical.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1.65 GPH flow rate for precise fuel delivery\u003c\/li\u003e\n  \u003cli\u003e90-degree spray angle for broad combustion coverage\u003c\/li\u003e\n  \u003cli\u003eSolid cone Type B pattern distributes droplets uniformly throughout the spray profile\u003c\/li\u003e\n  \u003cli\u003eRated for 100 psi operating pressure\u003c\/li\u003e\n  \u003cli\u003eBlue vial color coding allows fast visual identification during service\u003c\/li\u003e\n  \u003cli\u003eSupports smooth ignition and efficient combustion in larger oil burners\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement nozzle for oil burner equipment requiring a 1.65 GPH, 90-degree, solid cone Type B firing rate specification.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed oil burner technician or qualified HVAC service professional. Always shut down the burner and allow the system to cool before replacing the nozzle. Use a proper nozzle wrench to avoid damaging the nozzle adapter or electrodes during removal and installation. Follow all applicable local codes and equipment manufacturer specifications when setting electrode gaps and nozzle positioning.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlow Rate\u003c\/strong\u003e: 1.65 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\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: 1.65-90-B\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DELAVAN","offers":[{"title":"Default Title","offer_id":51284125385010,"sku":"1.65-90-B","price":17.79,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/309277563.jpg?v=1781069175","url":"https:\/\/voomisupply.com\/products\/delavan-1-65-90-b-oil-burner-nozzle-1-65-gph-90-degree","provider":"Voomi Supply","version":"1.0","type":"link"}
