The DM44 block includes a comprehensive installation guide with step-by-step instructions. Begin by verifying all measurements and ensuring the offset dimensions (86mm and 30° angle) are accurately aligned. Maintain the recommended 38mm clearance from combustibles for optimal safety.

This care will ensure your chimney system operates safely and efficiently.

The DM44 offset block is used in the Isokern Double Module (DM) chimney system to maintain optimal flue gas temperatures and prevent heat transference, ensuring efficient and safe operation of your heating appliance.

The DM44 block is constructed from pumice, a natural insulator known for its excellent thermal properties, which helps in maintaining consistent flue gas temperatures.

The DM44 block is suitable for a variety of heating appliances, including stoves, open fires, and cookers that burn wood, solid fuel, oil, or gas. However, it is not suitable for condensing appliances like Biomass and Pellets.

The Isokern DM44 block is HETAS Approved and CE marked, ensuring compliance with strict safety and performance standards.

The insulating properties of pumice used in the DM44 block allow the flue gases to quickly reach their optimal temperature, enhancing the performance of your heating appliance shortly after lighting. It also helps maintain the chimney's warmth longer.

The Isokern DM system is available in three outer casing sizes: DM36, DM44, and DM54, catering to various installation requirements.

Detailed installation guides are provided with the DM44 block, making the process simple and straightforward. Ensure you follow these instructions carefully for proper installation.
