It atomizes fuel oil into a fine, evenly distributed hollow-cone pattern that promotes efficient combustion in residential and light commercial oil-fired heating equipment. HVAC technicians and oil burner service professionals install this nozzle as part of routine burner maintenance or when upgrading combustion performance. The hollow-cone spray pattern is suited to specific burner head geometries where that distribution produces optimal flame shape and heat transfer.\u003c\/p\u003e\u003cp\u003eThis nozzle is used in oil-fired forced-air furnaces, boilers, and water heaters that require a 1.10 GPH firing rate and a 90-degree hollow-cone spray pattern. It is a standard service part replaced during annual burner tune-ups or when combustion analysis indicates degraded atomization. Proper nozzle selection by flow rate, spray angle, and pattern type is critical to achieving correct firing rate and combustion efficiency.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1.10 GPH flow rate for precise fuel delivery at the rated firing rate\u003c\/li\u003e\n\u003cli\u003e90-degree spray angle for wide flame pattern burner head configurations\u003c\/li\u003e\n\u003cli\u003eHollow-cone atomization pattern promotes even fuel distribution at the flame front\u003c\/li\u003e\n\u003cli\u003eStandard nozzle form factor compatible with common oil burner nozzle adapters\u003c\/li\u003e\n\u003cli\u003eDesigned for use with No. 1 and No. 2 fuel oil\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement nozzle for oil-fired residential and light commercial burners requiring a 1.10 GPH, 90-degree hollow-cone spray pattern.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eOil burner nozzles are installed by licensed oil burner technicians or qualified HVAC service professionals. Always shut down the burner and allow the system to cool before replacing the nozzle. Use the correct nozzle wrench to avoid damaging the nozzle adapter, and inspect the nozzle adapter and strainer for debris during every nozzle change. Verify firing rate, pump pressure, and combustion results with a calibrated combustion analyzer after installation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlow Rate\u003c\/strong\u003e: 1.10 GPH\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpray Angle\u003c\/strong\u003e: 90 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpray Pattern\u003c\/strong\u003e: Hollow Cone\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: 00110-90a1\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DELAVAN","offers":[{"title":"Default Title","offer_id":51467599905074,"sku":"00110-90A1","price":17.29,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/313945179.jpg?v=1783907594","url":"https:\/\/voomisupply.com\/products\/delavan-00110-90a1-oil-nozzle-1-10-gph-90-degree-hollow","provider":"Voomi Supply","version":"1.0","type":"link"}
