It accommodates roof pitches from 6\/12 to 12\/12, making it suitable for a wide range of residential roof slopes encountered in standard construction. This flashing creates a weather-tight seal at the roof penetration point, keeping moisture out while allowing the vent pipe to pass through cleanly. HVAC technicians and plumbers install this component during new construction or when replacing aging B-vent flashing on existing gas appliance installations.\u003c\/p\u003e\u003cp\u003eThis flashing is used on residential structures where natural-draft B-vent systems serve gas furnaces, water heaters, boilers, or other atmospheric-vent appliances. The adjustable design eliminates the need to stock multiple pitch-specific flashings, covering the steep-slope range from 6\/12 up to 12\/12 in a single SKU. It is intended for installation at the point where a 4-inch DVP B-vent pipe exits through a pitched roof deck.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAdjustable pitch range covers 6\/12 to 12\/12 roof slopes\u003c\/li\u003e\n\u003cli\u003eDesigned for 4-inch B-vent DVP pipe systems\u003c\/li\u003e\n\u003cli\u003eSingle flashing handles steep-slope applications without pitch-specific parts\u003c\/li\u003e\n\u003cli\u003eProvides weather-tight seal at roof penetration point\u003c\/li\u003e\n\u003cli\u003eCompatible with DURAVENT DVP B-vent system components\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with 4-inch DURAVENT DVP B-vent pipe and fittings on residential gas venting systems with steep roof pitches ranging from 6\/12 to 12\/12.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed HVAC technician or plumber in accordance with NFPA 54 and local mechanical code requirements. Shut down the gas appliance and allow the venting system to cool before beginning roof work. The flashing must be properly integrated with the roofing material to maintain a watertight seal, and all penetration clearances should follow the appliance manufacturer and vent system listing requirements. Do not compress or modify the flashing collar in a way that restricts the vent pipe movement or violates the listed clearances.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePipe Diameter\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePitch Range\u003c\/strong\u003e: 6\/12 to 12\/12\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVent Type\u003c\/strong\u003e: B-Vent (DVP)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Steep Roof Flashing\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: 04SRF\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DURAVENT","offers":[{"title":"Default Title","offer_id":51347974291762,"sku":"04SRF","price":75.8,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310553325.jpg?v=1782117064","url":"https:\/\/voomisupply.com\/products\/duravent-04srf-b-vent-adjustable-steep-roof-flashing-4-in","provider":"Voomi Supply","version":"1.0","type":"link"}
