It installs at the top of a Type B gas vent system and is designed to reduce downdrafts that can disrupt appliance draft and cause incomplete combustion. The cap fits 3-inch diameter B-vent pipe and uses a high-wind profile to maintain consistent negative pressure across the vent column. Licensed HVAC technicians and gas-appliance installers typically handle this termination hardware as part of a complete venting assembly on Category I gas appliances such as furnaces and water heaters.\u003c\/p\u003e\u003cp\u003eThis cap is suited for residential and light-commercial Category I gas appliance venting applications where outdoor wind exposure is a concern. It mounts at the vent termination point above the roofline or through a wall termination, protecting the vent opening from wind-induced backdrafting. It is appropriate for use in new construction venting runs and as a replacement termination cap on existing B-vent systems where the original cap has failed or been damaged.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eHigh-wind cap profile resists downdrafts and maintains proper appliance draft\u003c\/li\u003e\n\u003cli\u003eDesigned for 3-inch diameter Type B gas vent pipe\u003c\/li\u003e\n\u003cli\u003eServes as a vent termination point for Category I gas appliance systems\u003c\/li\u003e\n\u003cli\u003eReplacement-ready design suits both new installations and service calls\u003c\/li\u003e\n\u003cli\u003ePositioned at the top of the vent system to protect the vent opening from weather intrusion\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement termination cap for 3-inch Type B gas vent systems used with Category I gas appliances.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed HVAC technician or qualified gas-appliance installer in accordance with NFPA 54 and local gas codes. Shut off the gas supply and allow the appliance and vent system to cool completely before removing or replacing any vent termination components. Ensure the cap is secured per the vent manufacturer specifications and that vent clearances from combustibles and the roof surface meet code requirements. Do not operate the appliance until the termination cap is fully seated and the vent system has been inspected for proper assembly.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePipe Diameter\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVent Type\u003c\/strong\u003e: Type B Gas Vent (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\u003eCap Style\u003c\/strong\u003e: High Wind Top\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: 03VT\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DURAVENT","offers":[{"title":"Default Title","offer_id":51347838337330,"sku":"03VT","price":58.26,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310553312.jpg?v=1782114923","url":"https:\/\/voomisupply.com\/products\/duravent-03vt-b-vent-cap-3-inches-high-wind-top","provider":"Voomi Supply","version":"1.0","type":"link"}
