The double-wall, air-cooled design allows the chimney to expand both radially and lengthwise under high temperatures. DuraChimney® II is tested and listed for continuous operation at 1000°F flue gas temperatures, one hour at 1400°F and ten-minutes at 1700°F, in accordance with the UL 103 test standard.
