It provides a weather-tight termination base where the vent exits the roof deck, preventing water intrusion while maintaining the required clearances for double-wall B-vent systems. Rated for roofs with a pitch up to 5\/12, this flange is a standard component in residential and light-commercial gas appliance venting systems. HVAC technicians and plumbers install it as part of a complete B-vent assembly serving gas furnaces, water heaters, or boilers. The unit weighs 1.80 pounds.\u003c\/p\u003e\n\u003cp\u003eThis roof flange is used where a 5-inch B-vent riser passes through a sloped roof surface with a pitch no greater than 5\/12. Typical applications include natural-draft gas furnace venting, atmospheric water heater venting, and boiler vent stacks in residential construction. It is installed at the roofline as part of a Listed Type B vent system and works in conjunction with B-vent pipe sections, elbows, and a storm collar to complete the through-roof assembly.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eFits 5-inch Type B double-wall gas vent pipe\u003c\/li\u003e\n  \u003cli\u003eRated for roof pitches up to 5\/12\u003c\/li\u003e\n  \u003cli\u003eStandard B-vent roof flange configuration for through-roof penetrations\u003c\/li\u003e\n  \u003cli\u003eLightweight at 1.80 pounds for ease of handling on the roof\u003c\/li\u003e\n  \u003cli\u003eDesigned to integrate with Listed B-vent system components\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and standard component for 5-inch Type B double-wall gas vent systems on roofs with a pitch up to 5\/12.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by a licensed HVAC technician or plumber in accordance with the appliance manufacturer instructions and the International Fuel Gas Code (IFGC).
