It meters and atomizes fuel oil into the combustion chamber of an oil-fired burner, producing the fine mist required for efficient ignition and stable flame. The hollow cone pattern distributes fuel along the outer edge of the spray envelope, which suits burner heads designed for that atomization profile. Licensed oil burner technicians and HVAC service professionals install and replace this nozzle during routine seasonal tune-ups or when combustion performance degrades.\u003c\/p\u003e\u003cp\u003eThis nozzle is appropriate for residential and light-commercial oil-fired heating equipment, including forced-air furnaces and boilers equipped with pressure-atomizing gun-type burners. It is selected when the burner manufacturer or equipment service manual specifies a 3.00 GPH, 90-degree, hollow cone nozzle. Always verify the firing rate, spray angle, and spray pattern against the appliance nameplate and the burner manufacturer's nozzle specification chart before installation.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e3.00 GPH firing rate for medium-to-high output oil burner applications\u003c\/li\u003e\n\u003cli\u003e90-degree spray angle suits burner heads requiring a wide atomization envelope\u003c\/li\u003e\n\u003cli\u003eHollow cone spray pattern concentrates fuel along the outer ring of the spray for compatible combustion chamber geometries\u003c\/li\u003e\n\u003cli\u003eCompact, lightweight design at 0.10 pounds for easy field handling and storage\u003c\/li\u003e\n\u003cli\u003eStandardized nozzle thread for direct replacement in pressure-atomizing gun-type burners\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement nozzle for pressure-atomizing oil burners that specify a 3.00 GPH, 90-degree hollow cone nozzle.

Shut down the burner and allow it to cool completely before servicing; close the fuel supply valve and de-energize the unit at the service disconnect. Use a proper nozzle wrench to remove the old nozzle and install the replacement without over-tightening, which can damage the nozzle seat or adapter. After installation, verify combustion performance with appropriate test instruments per local codes and the appliance manufacturer's service instructions.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlow Rate\u003c\/strong\u003e: 3.00 GPH\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpray Angle\u003c\/strong\u003e: 90 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpray Pattern\u003c\/strong\u003e: Hollow Cone\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eItem Weight\u003c\/strong\u003e: 0.10 pounds\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: 00300-90a7\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DELAVAN","offers":[{"title":"Default Title","offer_id":51467394941234,"sku":"00300-90A7","price":14.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/313945234.jpg?v=1783903417","url":"https:\/\/voomisupply.com\/products\/delavan-00300-90a7-oil-burner-nozzle-3-00-gph-90-degree","provider":"Voomi Supply","version":"1.0","type":"link"}
