It is identified by a red vial for quick field identification. This Type A hollow-cone nozzle is engineered for oil-fired burners where the air pattern is also hollow cone in configuration. Droplet distribution concentrates on the outer edge of the spray cone, which promotes reliable ignition and low-noise combustion. Licensed oil burner technicians install this nozzle as part of routine annual service or burner tune-up procedures.\u003c\/p\u003e\u003cp\u003eThis nozzle is suited for residential and light commercial oil-fired heating equipment, including forced-air furnaces, boilers, and water heaters equipped with gun-style oil burners. The Type A hollow-cone pattern is appropriate for throughputs up to 2.00 GPH, making the 1.00 GPH flow rate well within its intended operating range. It is a direct service replacement installed during seasonal startup, efficiency testing, or combustion analysis service calls.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1.00 GPH flow rate for precise fuel delivery in oil-fired burner applications\u003c\/li\u003e\n\u003cli\u003e90-degree hollow-cone spray angle matches burner air patterns designed for hollow-cone atomization\u003c\/li\u003e\n\u003cli\u003eRated for 100 psi operating pressure\u003c\/li\u003e\n\u003cli\u003eDroplet distribution concentrated at cone perimeter promotes stable ignition and quiet combustion\u003c\/li\u003e\n\u003cli\u003eRed vial color-coding allows fast identification without reading stamped markings in the field\u003c\/li\u003e\n\u003cli\u003eType A hollow-cone design supports throughputs up to 2.00 GPH\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement nozzle for oil burners that require a hollow-cone Type A spray pattern at 1.00 GPH and a 90-degree angle.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eOil burner nozzles are replaced by licensed oil burner technicians or qualified heating service professionals. Shut down the burner and allow the fuel system to depressurize before removing the nozzle assembly. Use a proper nozzle wrench to avoid damaging the nozzle adapter or electrodes during removal and installation. Verify combustion performance with a flue gas analyzer after replacement to confirm proper air-fuel ratio and efficiency.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlow Rate\u003c\/strong\u003e: 1.00 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: Hollow Cone\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNozzle Type\u003c\/strong\u003e: Type A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVial Color\u003c\/strong\u003e: Red\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: 1.00-90-A\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DELAVAN","offers":[{"title":"Default Title","offer_id":51284025442610,"sku":"1.00-90-A","price":17.79,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/309276833.jpg?v=1781066438","url":"https:\/\/voomisupply.com\/products\/delavan-1-00-90-a-oil-burner-nozzle-1-gph-90-degree-hollow-cone","provider":"Voomi Supply","version":"1.0","type":"link"}
