The proprietary twist-lock connection eliminates use of clamps or mechanical fasteners and saves installation time. Only one penetration is needed through the roof or the wall for both exhaust and combustion air. Multiple pipe lengths and telescoping pipe extensions eliminate field cutting of pipe. CVS is the only concentric vent system to incorporate o-rings on the inner wall and outer casing to prevent exhaust or combustion air leakage. Custom adapters are available to transition from co-linear to coaxial venting systems. The built-in condensate management system prevents standing condensation. The Concentric Venting System is a fully sealed, gas tight system to deliver superior performance with the heating unit.\u003c\/p\u003e\n\u003cp\u003eDuraVent Concentric Vent System has a 3” inner diameter and 5” outer diameter.\u003c\/p\u003e\n\u003ch1\u003eWhat's Included\u003c\/h1\u003e\n\u003cul\u003e\n\u003cli\u003eStorm Collar\u003cbr\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch1\u003eFeatures\u003c\/h1\u003e\n\u003cul\u003e\n\u003cli\u003eUse to maintain a weather tight resistant seal between the pipe and the flashing for vertical terminations.\u003cbr\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch1\u003eSpecifications\u003c\/h1\u003e\n\u003ctable width=\"100%\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eDuraVent\u003cbr\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eModel\u003c\/td\u003e\n\u003ctd\u003e35CVS-SC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSeries\u003c\/td\u003e\n\u003ctd\u003e3\" x 5\" Concentric Vent System\u003cbr\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Type\u003c\/td\u003e\n\u003ctd\u003eStorm Collar\u003cbr\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eA\u003c\/td\u003e\n\u003ctd\u003e5 1⁄8”\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eB\u003c\/td\u003e\n\u003ctd\u003e10”\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch2\u003eTechnical Dimensions\u003c\/h2\u003e\n\u003cdiv style=\"text-align: center;\"\u003e\u003cimg style=\"float: none;\" alt=\"\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0813\/8725\/8148\/files\/DVCSV-StormCollar_240x240.jpg?v=1696907509\"\u003e\u003c\/div\u003e\n\u003ch1\u003eWarranty\u003c\/h1\u003e\n\u003ctable width=\"100%\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 46.5779%;\" data-mce-style=\"width: 46.5779%;\"\u003e\n\u003cdiv style=\"text-align: start;\" data-mce-style=\"text-align: start;\"\u003e\u003cimg style=\"float: none;\" alt=\"\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0100\/7917\/4734\/files\/Lifetime_Warranty_Badge_240x240.jpg?v=1682130235\" data-mce-style=\"float: none;\" data-mce-src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0100\/7917\/4734\/files\/Lifetime_Warranty_Badge_240x240.jpg?v=1682130235\"\u003e\u003c\/div\u003e\n\u003c\/td\u003e\n\u003ctd style=\"width: 50.3802%;\" data-mce-style=\"width: 50.3802%;\"\u003eDuraVent, Inc.
