The DM44 - 180mm ID x 600mm high access flue block is an integral part of the Isokern DM block system, renowned for its exceptional quality and performance. This double module system is designed to maintain optimal flue gas temperatures while minimising heat transference to the outer casing. By keeping the inner and outer components separate, the system allows for thermal movement, reducing the risk of cracking and subsequent leaks.

Quick and easy to assemble, the DM44 is part of a range that includes three outer casing sizes: DM36, DM44, and DM54. This versatile flue block is compatible with various heating appliances, such as wood-burning stoves, open fires, and cookers using solid fuel, oil, or gas (excluding condensing appliances including Biomass & Pellets). Pumice, a natural insulator, is the key material in this product, offering exceptional thermal properties that help maintain optimal appliance performance and minimise condensation and soot build-up.

HETAS Approved and CE marked, the Isokern DM system boasts impressive certification, ensuring reliable and safe usage. For installation guidance, refer to the provided manuals.
