The DM54 - 345mm ID x 300mm high flue block is part of the renowned Isokern DM (Double Module) block system, crafted for superior chimney performance. This advanced flue block maintains optimum flue gas temperatures while minimizing heat loss to the exterior casing. The double wall design features a separation between the inner and outer components, allowing for thermal movement that minimizes risks of cracking and leakage.
Constructed from natural pumice, a unique insulator, the DM54 block quickly brings flue gases to optimal temperatures, ensuring peak performance of your heating appliance. As temperatures reduce, the pumice retains heat, further enhancing performance and reducing condensation and soot build-up. Available in multiple sizes (DM36, DM44, and DM54), the DM system is versatile and fits a range of heating applications.
It is suitable for inserts, stoves, open fires, and cookers using wood, solid fuel, oil, or gas. Note, it isn't designed for condensing appliances like biomass and pellet stoves. The Isokern DM is HETAS approved and CE marked, validating its high-quality and safety standards.
For installation, detailed guides are available to ensure a straightforward assembly process.
