DuraChimney® II Air-Cooled Chimney System
DuraChimney® II is an exceptional factory-built alternative to pre-fabricated masonry chimneys. DuraChimney® II is a unitized, lightweight design which eliminates the need for field assembly of pipe sections, allowing for faster installation.
DuraChimney® II is designed to stay cool on the outside, to provide a hot draft on the inside and to provide a fire-safe design that protects both the chimney and the building.
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.Specifications
DuraChimney II is a double-wall, air-cooled chimney system for use with masonry fireplaces which burn wood, oil, coal, or gas.
