The 45-degree bend allows installers to route flue gases around obstructions or transition vent runs at a shallower angle than a standard 90-degree elbow. The double-wall construction maintains draft performance and meets the clearance requirements associated with Type B vent. Licensed HVAC technicians and plumbers install this fitting as part of a complete B-vent system serving furnaces, water heaters, boilers, and other Category I appliances.\u003c\/p\u003e\n\u003cp\u003eThis elbow fits an 8-inch B-vent system and is suited for residential and light commercial applications where a 45-degree directional change is needed in the vertical or horizontal vent run. The round profile and standard flat configuration allow it to integrate with other standard 8-inch B-vent components. It is commonly used in new construction and replacement venting projects where local mechanical codes require listed Type B gas vent fittings.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e45-degree elbow angle for gradual directional changes in vent runs\u003c\/li\u003e\n  \u003cli\u003eDouble-wall round construction maintains proper flue gas temperature and draft\u003c\/li\u003e\n  \u003cli\u003e8-inch nominal size matches standard B-vent system components\u003c\/li\u003e\n  \u003cli\u003eStandard flat profile for straightforward integration into existing vent assemblies\u003c\/li\u003e\n  \u003cli\u003eLightweight at 2.08 pounds for easier overhead and attic installation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation fitting for 8-inch Type B double-wall round gas vent systems used with Category I natural gas and propane appliances.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eType B vent installation should be performed by a licensed HVAC technician or plumber in accordance with NFPA 54, the International Fuel Gas Code, and local mechanical codes. Shut off the gas supply and allow the appliance to cool completely before servicing or modifying any vent connection. Maintain all required clearances to combustibles as specified by the vent system manufacturer and applicable codes. Do not mix B-vent components from different manufacturers within the same vent system unless the components are listed for combined use.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eElbow Degree\u003c\/strong\u003e: 45 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShape\u003c\/strong\u003e: Round\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConstruction\u003c\/strong\u003e: Double Wall\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSize\u003c\/strong\u003e: 8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eProfile\u003c\/strong\u003e: Standard Flat\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2.08 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: HART COOLEY\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 8r45\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HART \u0026 COOLEY","offers":[{"title":"Default Title","offer_id":51233706737970,"sku":"8R45","price":92.82,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/307629056.jpg?v=1780107248","url":"https:\/\/voomisupply.com\/products\/hart-cooley-8r45-b-vent-45-degree-elbow-8-inch-round","provider":"Voomi Supply","version":"1.0","type":"link"}
