It meters and atomizes fuel oil as it enters the combustion chamber, converting liquid fuel into a fine, combustible mist for consistent ignition and clean burn. This nozzle is a consumable service part installed by licensed oil burner technicians and heating contractors during annual maintenance, nozzle replacement, or burner tune-up service on residential and light commercial oil-fired heating equipment.\u003c\/p\u003e\u003cp\u003eThe 85-70a1 is suited for residential oil-fired furnaces, boilers, and water heaters where a 0.85 GPH firing rate and a 70-degree hollow cone spray pattern are specified by the equipment manufacturer or burner setup sheet. The hollow cone pattern is commonly called for in applications where flame shape and combustion chamber geometry require spray concentrated at the outer edge of the cone rather than through the center. Always verify the required GPH, spray angle, and nozzle type against the appliance rating plate or burner manufacturer specifications before installation.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.85 GPH flow rate for precise fuel metering at the rated firing rate\u003c\/li\u003e\n\u003cli\u003e70-degree spray angle matches burner and combustion chamber geometry requirements\u003c\/li\u003e\n\u003cli\u003eType A hollow cone spray pattern concentrates atomized fuel at the cone perimeter\u003c\/li\u003e\n\u003cli\u003eDirect replacement nozzle for scheduled oil burner maintenance and tune-up service\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement nozzle for oil-fired furnaces, boilers, and water heaters specifying a 0.85 GPH, 70-degree, Type A hollow cone nozzle.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed oil burner technician or qualified heating contractor. Shut down the burner and allow all components to cool before servicing the nozzle assembly. Use a proper nozzle wrench to remove and install the nozzle to avoid damaging the nozzle adapter or electrodes. After replacement, verify combustion performance with appropriate test instruments per NFPA 31 guidelines before returning the appliance to service.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlow Rate\u003c\/strong\u003e: 0.85 GPH\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpray Angle\u003c\/strong\u003e: 70 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpray Pattern\u003c\/strong\u003e: Type A 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: 85-70a1\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DELAVAN","offers":[{"title":"Default Title","offer_id":51621235425586,"sku":"85-70A1","price":21.53,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/delavan_2_66c6b0a0-2a35-4367-be98-c66f24cf8b65.jpg?v=1787351711","url":"https:\/\/voomisupply.com\/products\/delavan-85-70a1-oil-burner-nozzle-0-85-gph-70-degree","provider":"Voomi Supply","version":"1.0","type":"link"}
