It fits 8-inch diameter B-vent pipe and uses a high wind top design to resist downdrafts and maintain stable draft performance in Category I gas appliance venting systems. This cap installs at the uppermost point of a vertical vent stack and is a standard component in residential and light commercial gas appliance venting projects. Licensed HVAC technicians and gas appliance installers typically select this cap when vertical terminations are exposed to prevailing winds or elevated roofline conditions.\u003c\/p\u003e\u003cp\u003eThe 08VT is suited for vertical termination applications on Category I gas appliances, including natural gas and propane furnaces, water heaters, and boilers vented through B-vent pipe systems. It is intended for outdoor rooftop installation where vertical vent runs terminate above the roofline. The high wind top geometry helps prevent wind-induced downdraft from disrupting combustion appliance draft, which is a critical performance factor in exposed or high-elevation installations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eHigh wind top design reduces downdraft risk at vertical vent terminations\u003c\/li\u003e\n\u003cli\u003eFits 8-inch B-vent pipe diameter\u003c\/li\u003e\n\u003cli\u003eIntended for vertical terminations only — not approved for horizontal or side-wall exit\u003c\/li\u003e\n\u003cli\u003eCompatible with Category I gas appliance venting applications\u003c\/li\u003e\n\u003cli\u003eInstalls at the top of the vent stack without penetrating the roof plane\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style termination cap for 8-inch B-vent vertical vent systems used in Category I gas appliance applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed HVAC technician or qualified gas appliance service professional in accordance with NFPA 54 and the appliance manufacturer venting requirements. Shut down and allow the gas appliance and vent system to cool completely before removing or installing any vent components. Verify that the cap is secured and sealed per local code requirements before restoring appliance operation. This cap is approved for vertical terminations only and must not be used on horizontal or side-wall vent exits.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePipe Diameter\u003c\/strong\u003e: 8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTermination Type\u003c\/strong\u003e: Vertical only\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVent Type\u003c\/strong\u003e: B-Vent\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Category I gas appliance venting\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWind Resistance\u003c\/strong\u003e: High wind top design\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: DURAVENT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 08VT\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DURAVENT","offers":[{"title":"Default Title","offer_id":51343089402162,"sku":"08VT","price":91.31,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310553273.jpg?v=1782016264","url":"https:\/\/voomisupply.com\/products\/duravent-08vt-b-vent-cap-8-inch-high-wind-top","provider":"Voomi Supply","version":"1.0","type":"link"}
