The DM36 - 150mm ID x 125mm high starter flue block is an integral part of the Isokern DM block system, known for its high-quality design and performance. This double-module system maintains flue gas temperatures while effectively preventing heat transference to the outer casing. The unique double wall design allows for thermal movement, reducing the risk of cracks and leaks.
Simple and quick to install, the DM36 is versatile and suitable for use with a range of heating appliances including stoves, open fires, cookers, and inserts burning wood, solid fuel, oil, or gas. However, it's not suitable for condensing appliances like Biomass and Pellets. Constructed from natural pumice, this starter flue block is an excellent insulator, allowing your chimney to reach optimal temperatures swiftly, enhancing the performance of your heating appliance and minimizing condensation and soot buildup.
Approved by HETAS and CE marked, this product meets stringent standards. Follow the installation instructions in the provided guides for the best results.
