This triple-wall chimney features two insulating layers (refractory blanket, plus air space). The refractory 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 is 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\u003ch3\u003e\n\u003cstrong\u003e\u003c\/strong\u003e\u003cbr\u003e\n\u003c\/h3\u003e\n\u003ch3\u003e\u003cstrong\u003eFeatures\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eAdjusts from a minimum of 4 1⁄4” to a maximum of 7 1⁄4” wall thickness, and fits between standard wall studs.\u003c\/li\u003e\n\u003cli\u003eTo accommodate thicker walls, the telescoping pieces can be extended up to 16” with a field-fabricated extension installed.\u003c\/li\u003e\n\u003cli\u003eMust be installed with DuraPlus chimney pipe horizontally through the wall and extend a minimum of 2” into the room beyond the interior wall.\u003c\/li\u003e\n\u003cli\u003eInterior trim ring painted black.\u003c\/li\u003e\n\u003cli\u003eFor adapters, see DVL and DuraBlack section.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003ch4\u003e\u003cstrong\u003eMaterials and Construction\u003c\/strong\u003e\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003e.016” 430 stainless steel outer wall\u003c\/li\u003e\n\u003cli\u003e.016” 430 stainless steel inner liner.\u003c\/li\u003e\n\u003cli\u003e.018” galvanized steel outer wall.\u003c\/li\u003e\n\u003cli\u003e.018” aluminized steel intermediate liner.\u003c\/li\u003e\n\u003cli\u003eInsulated layers plus ventilated air space.\u003c\/li\u003e\n\u003cli\u003eLocks tightly with a precision twist-lock connection.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e \u003cbr\u003e\u003c\/p\u003e\n\u003ch3\u003e\n\u003cstrong\u003e\u003c\/strong\u003e\u003cbr\u003e\n\u003c\/h3\u003e\n\u003ch3\u003e\u003cstrong\u003eSpecifications\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cdiv style=\"text-align: center;\"\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003cdiv style=\"text-align: center;\"\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003cdiv style=\"text-align: center;\"\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003cdiv style=\"text-align: center;\"\u003e\n\u003ctable style=\"width: 540px;\" width=\"412\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd style=\"text-align: left;
