The DM36 350mm square x 250mm high casing & soot door is a top-tier product in our Isokern DM block system range. This double wall system expertly maintains flue gas temperatures while ensuring that heat is not transferred to the outer casing, making it safe and efficient. The innovative design separates the inner and outer components, accommodating thermal movement to reduce the risk of cracking, leaks, or stains.
Its installation is both quick and straightforward, making it a top choice for professionals and DIY enthusiasts alike. Available in three outer casing sizes - DM36, DM44, and DM54, it is suitable for a wide range of applications including stoves, open fires, inserts, and cookers that burn wood, solid fuel, oil, or gas. However, it is not recommended for condensing appliances such as Biomass and Pellets.
Crafted from pumice, a natural insulator, this casing ensures that your heating appliance rapidly reaches optimal performance and maintains temperature efficiently. Isokern DM is both HETAS Approved and CE marked, offering you peace of mind in terms of safety and regulatory compliance. For optimal results, always refer to the installation guides provided.
