DM54 Chimney System

The most popular and widely used Isokern Dual Module (DM) Chimney System—the Isokern DM54 Chimney System—is up to 14” diameters and can be used on all of the larger boxes, such as the 42”- 46” Standard Series and the 36”-72” Magnum Series. Unlike traditional masonry, modular concrete and steel/metal stack chimney system designs, the Isokern DM Chimney System was built to last a lifetime—resisting cracking, deflecting and oxidation.

Component-based with an inner liner and external casing, the Isokern DM Chimney System is the only all-masonry chimney system tested and listed to UL 103HT (High Temperature) standards. The dual modular design allows for more diverse, lightweight, masonry-type installations and each component is built with tongue and groove construction, enabling a tighter fit for maximum safety and consistent installation.
