Additional Information: The DuraChimney II system is a double-wall air-cooled chimney system for masonry fireplaces which burn wood, oil, coal, or gas. DuraChimney II is an exceptional 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.
