The DM54 - 345mm ID x 150mm high starter flue block is an exceptional component in the Isokern DM chimney system. This double-module (DM) system is designed to maintain optimum flue gas temperatures while preventing heat transference to the outer casing, making it a high-quality system chimney. Featuring a pumice construction, known for its natural insulating properties, the DM54 flue block ensures rapid temperature attainment and consistent performance.
It keeps the chimney warm longer, aiding in reducing condensation and soot build-up. Available in three outer casing sizes - DM36, DM44, and DM54, this system is compatible with inserts, stoves, open fires, and cookers using wood, solid fuel, oil, or gas (excluding condensing appliances such as Biomass and Pellets). The system is HETAS approved and CE marked, ensuring safety and compliance with international standards.
Easy to install, the DM54 starter flue block is a reliable choice for both professionals and DIY enthusiasts.
