The DM, or dual module, chimney system is a component based chimney system that has an inner liner and external casing.  The modular design of this system allows for more diverse, lightweight chimney installations for fireplaces and other applications.  Isokern DM chimney components are built with tongue and groove construction, enabling a tighter fit for maximum safety and consistent installation.  The tongue and groove construction also makes the propensity for false chimneys (in the actual chimney structure) non-existent.  The DM System is also 100% zero clearance for construction purposes.

The absence of co-efficiency makes our chimney system especially desirable in cold weather climates as it is not prone to cracking.  Traditional masonry and metal stack chimney systems (which have different types of material and therefore co-efficiency exists) do crack and deflect, which results in the home or business owner having to replace or repair their chimney system.

All of the Isokern DM Chimney components
are tested and listed to UL103HT.

The Isokern Fireplace and Chimney System is also
tested and listed to ULC S610.

Made from the same high quality insulating pumice stone as Isokern DM chimney components, the Isokern offset block component offers the ability to move vertical chimneys from side to side to pass objects above the firebox. It is always preferred to build a vertical chimney for maximum draft performance; however, this may not be feasible with current architectural designs.

The offset blocks may be moved in various directions, but always allowing the angled hole to be smooth and clear. Offsetting at the top plate of the firebox is the preferred method so as to allow the speed of smoke to more quickly reach vertical travel for best draft.

Once the offset cantilevers off the side of the firebox by three or more, it must be supported by a grouted column block or anchored steel columns. The offset block measures 25" x 21.5" x 6" in height. They are monolithic in construction with angled centers. Each offset block allows for up to 3" of horizontal movement.

ALWAYS consult with your local distributor/dealer for proper installation instructions, and to discuss project specific guidelines.

The Isokern brickledge is a proprietary component that is supported by the DM chimney components. The Isokern brickledge component is uniquely designed to allow a brick or stone finished chimney to exit out the roof for interior fireplace installations. It eliminates the cost of having excess masonry carried down the footer.

A brickledge can be used in almost any interior application where masonry above a roof is desired. This allows for a typical 3 x 3 foot or 4 x 4 foot wide chimney profile. The brickledge measures 31.5" x 31.5" x 3" and is reinforced. Refer to your local building codes or your architect prior to installation to make calculations for providing adequate footers for additional weights.

Please consult with your builder, sales representative or local dealer for more specific information pertaining to proper installation, larger dimensions and application use.
