The DM44 - 180mm ID x 440mm sq. DM support block is an integral part of the Isokern DM block system—a high-quality system chimney that combines durability and efficiency. This double wall system ensures optimal flue gas temperatures while preventing heat transfer to the outer casing.
By allowing thermal movement, it minimizes the risk of cracks and subsequent leakage or staining, making it a highly reliable choice for various heating applications.Constructed from pumice, a natural insulator, the DM block maintains an optimal temperature for flue gases, enhancing the performance of your heating appliance. Pumice's unique insulating properties enable quick warmth, efficient heating, and extended performance time by retaining heat longer. This reduces condensation and soot build-up, ensuring a clean and efficient chimney system.The DM block system is available in three casing sizes—DM36, DM44, and DM54—offering flexibility for different installation requirements.
This support block specifically measures 180mm in internal diameter and 440mm square, featuring a lower spigot for easy adaptor connection. It is compatible with inserts, stoves, open fires, and cookers using wood, solid fuel, oil, or gas (excluding condensing appliances like Biomass & Pellets).Certified and approved by HETAS and CE marked, the Isokern DM system meets high safety and performance standards. Detailed installation instructions are provided to ensure seamless assembly and integration into your heating system.
