DuraPlus® 2 (DP2)

Double-Wall Chimney
The DP2, with its double-wall, all-stainless-steel chimney and insulation, minimizes heat loss through the chimney walls, and can withstand the intense heat. The free-floating inner lining is attached only to the male coupler at the top, expanding and contracting freely with temperature fluctuations. The external casing of the DP2 carries the structural load.
