This triple-wall chimney features two insulating layers (ceramic blanket, plus air space). The ceramic blanket insulation is held securely in position, eliminating hot spots common with loose-fill type insulations. In the event of a creosote fire, the compressible blanket insulation permits the chimney liner to expand outwardly in a radial direction.\u003c\/p\u003e\n\u003cp\u003eDesigned for normal, continuous operation at 1000°F flue gas temperatures, DuraPlus® subjected to rigorous and stringent HT requirements of the UL standard, including one hour at 1400°F, plus three ten minute chimney fire tests at 2100°F.\u003c\/p\u003e\n\u003ch1\u003eWhat's Included\u003c\/h1\u003e\n\u003cul\u003e\n\u003cli\u003eSquare Ceiling Support Box\u003c\/li\u003e\n\u003cli\u003eTrim\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch1\u003eFeatures\u003cstrong\u003e\u003c\/strong\u003e\n\u003c\/h1\u003e\n\u003cdiv class=\"descr\" style=\"text-align: start;\"\u003e\n\u003cul\u003e\n\u003cli\u003eDuraPlus square ceiling support box\u003c\/li\u003e\n\u003cli\u003eUse with flat, vaulted, or cathedral ceilings.\u003c\/li\u003e\n\u003cli\u003eSquare Ceiling Support Box is painted black.\u003c\/li\u003e\n\u003cli\u003eSupports up to 35’ of DuraPlus Chimney.\u003c\/li\u003e\n\u003cli\u003eStarter Section built-in.\u003c\/li\u003e\n\u003cli\u003eFor adapters, see DVL and DuraBlack section.\u003c\/li\u003e\n\u003cli\u003eTrim included.\u003c\/li\u003e\n\u003cli\u003eUL Listed to UL 103HT (MH7399).\u003cbr\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch1\u003eSpecifications\u003c\/h1\u003e\n\u003ctable style=\"width: 100.079%; height: 73.5332px;\" width=\"100%\"\u003e\n\u003ctbody\u003e\n\u003ctr style=\"height: 18.3833px;\"\u003e\n\u003ctd style=\"width: 59.7062%; height: 18.3833px;\"\u003eModel\u003c\/td\u003e\n\u003ctd style=\"width: 40.0585%; height: 18.3833px;\"\u003eDV-8DP-CS36\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 18.3833px;\"\u003e\n\u003ctd style=\"width: 59.7062%; height: 18.3833px;\"\u003eProduct Type\u003cbr\u003e\n\u003c\/td\u003e\n\u003ctd style=\"width: 40.0585%; height: 18.3833px;\"\u003eCeiling Support Box\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 18.3833px;\"\u003e\n\u003ctd style=\"width: 59.7062%; height: 18.3833px;\"\u003eSize\u003cbr\u003e\n\u003c\/td\u003e\n\u003ctd style=\"width: 40.0585%; height: 18.3833px;\"\u003e8\"\u003cbr\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 18.3833px;\"\u003e\n\u003ctd style=\"width: 59.7062%; height: 18.3833px;\"\u003eLength\u003c\/td\u003e\n\u003ctd style=\"width: 40.0585%; height: 18.3833px;\"\u003e36\"\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch2\u003eTechnical Dimensions\u003c\/h2\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0100\/7917\/4734\/files\/CSB_240x240.jpg?v=1657828096\" style=\"float: none; display: block; margin-left: auto; margin-right: auto;\"\u003e\u003c\/p\u003e\n\u003ch2\u003e\u003cspan style=\"color: #000000;\"\u003eCeiling Pitch\u003c\/span\u003e\u003c\/h2\u003e\n\u003ctable width=\"100%\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eDuraBlack\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cstrong\u003eDVL\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cstrong\u003eUse\u003c\/strong\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e0\/12 - 4\/12\u003c\/td\u003e\n\u003ctd\u003e0\/12 - 6\/12\u003c\/td\u003e\n\u003ctd\u003e11\" Support Box\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e5\/12 - 9\/12\u003c\/td\u003e\n\u003ctd\u003e7\/12 - 13\/12\u003c\/td\u003e\n\u003ctd\u003e24\" Support Box\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e10\/12 - 14\/12\u003c\/td\u003e\n\u003ctd\u003e14\/12 - 20\/12\u003c\/td\u003e\n\u003ctd\u003e36\" Support Box\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e","brand":"Majestic","offers":[{"title":"Default Title","offer_id":46444755321002,"sku":"DV-8DP-CS36","price":555.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0100\/7917\/4734\/files\/Majestic-DuraPlus-8-x-36-Square-Ceiling-Support-Box.jpg?v=1780196320","url":"https:\/\/usfireplacestore.com\/products\/majestic-duraplus-8-x-36-square-ceiling-support-box","provider":"US Fireplace Store","version":"1.0","type":"link"}
