Dual Module Chimney System

The DM54 Chimney System is a zero clearance system made with our Icelandic pumice, a natural insulator, separating our system from all other chimneys. The insulating properties of pumice allow the flue gases in the chimney to quickly reach their optimum temperature, enabling the heating appliance to perform efficiently. It also keeps the chimney warmer longer as the heat output of the fireplace decreases. This not only aids performance, but reduces the likelihood of condensation and soot build-up.

Our component based system is made up of inner and outer blocks that are installed with staggered joints for safety and stability. The double layer of pumice blocks, separated by an air gap, maximizes the chimney performance. This system is the only masonry chimney system tested and listed to UL 103HT (2100° High Temperature) standards.

DM54: Taking Chimney
Systems to New Heights

The dual module design allows for more diverse, lightweight, masonry-type installations. Each component is built with tongue and groove construction with offset joints, enabling a tighter fit for maximum safety and consistent installation.

In addition, the DM Chimney System, with 100% zero-clearance to combustibles, makes it the easiest flue system to install.
