The orifice meters gas flow into the burner assembly, controlling combustion air-fuel mixture at the point of ignition. Brass construction provides corrosion resistance and dimensional stability under repeated thermal cycling. This component is a direct OEM-style replacement part, typically installed by licensed HVAC technicians or gas appliance service professionals during burner maintenance, gas conversion, or combustion performance restoration.\u003c\/p\u003e\u003cp\u003eThe 196840 orifice is suited for Reznor unit heaters and related heating equipment that require a size 4 orifice in the burner or manifold assembly. It is commonly replaced during gas type conversions, orifice cleaning failures, or as part of a scheduled burner service. The brass material is compatible with natural gas and propane applications where the corresponding orifice sizing is specified by the equipment manufacturer.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eBrass construction for corrosion resistance and thermal durability\u003c\/li\u003e\n\u003cli\u003eSize 4 orifice for precise gas flow metering\u003c\/li\u003e\n\u003cli\u003eOEM Reznor replacement part for accurate fitment\u003c\/li\u003e\n\u003cli\u003eSuitable for burner assembly service and gas conversion work\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement orifice for Reznor heating equipment requiring a size 4 brass orifice in the burner or manifold assembly.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed HVAC or gas service technician in accordance with applicable local codes and IFGC requirements. Shut off the gas supply and allow the unit to cool completely before removing or replacing any orifice. Use the correct orifice wrench or fitting tool to avoid damaging the brass threads or orifice bore. Verify the replacement orifice size matches the equipment manufacturer specifications for the fuel type in use before returning the unit to service.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Brass\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOrifice Size\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: REZNOR\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 196840\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"REZNOR","offers":[{"title":"Default Title","offer_id":51201989214514,"sku":"196840","price":49.07,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/307148571.jpg?v=1779698821","url":"https:\/\/voomisupply.com\/products\/reznor-196840-brass-orifice-size-4","provider":"Voomi Supply","version":"1.0","type":"link"}
