This fitting redirects venting at a right angle, allowing installers to route exhaust from gas-fired appliances around structural obstructions or transition between vertical and horizontal runs. The double-wall construction maintains flue gas temperature to support proper draft and reduces heat transfer to surrounding combustible materials. This elbow is a standard component in residential and light-commercial B-vent installations and is handled by licensed HVAC technicians and gas appliance installers.\u003c\/p\u003e\u003cp\u003eThis elbow is used in Type B double-wall vent systems serving natural gas and propane appliances such as furnaces, boilers, water heaters, and space heaters. It is suited for residential and light-commercial applications where a 90-degree directional change is required within the vent run. The 8-inch diameter sizing accommodates the venting requirements of higher-capacity appliances. Installers select this fitting when the vent path must make a full right-angle turn before connecting to a vertical chase or roof termination.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e90-degree elbow provides a full right-angle directional change in the vent run\u003c\/li\u003e\n\u003cli\u003eDouble-wall round construction maintains draft temperature and limits heat transfer\u003c\/li\u003e\n\u003cli\u003e8-inch diameter fits standard Type B vent system components of the same size\u003c\/li\u003e\n\u003cli\u003eDesigned for use with natural gas and propane appliance venting\u003c\/li\u003e\n\u003cli\u003eConnects within a modular B-vent system for straightforward assembly\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and new-installation fitting for 8-inch Type B double-wall round gas vent systems in residential and light-commercial applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed HVAC technician or gas appliance installer in accordance with NFPA 54 and the appliance manufacturer's venting instructions.
