Detailed Benefits
Superior Thermal Efficiency
Efficient operation of your chimney is all about maintaining the right balance of temperature. The DM36 achieves this by ensuring that flue gases rapidly reach and maintain optimal temperatures. This efficient heat retention prevents condensation, which is a major cause of corrosion and performance degradation in chimney systems.
Natural Insulation with Pumice
Natural pumice is renowned for its excellent insulating properties. By using this material, the DM36 provides an extra layer of insulation that not only enhances safety but also improves long-term durability. This means fewer maintenance requirements and a longer-lasting installation.
Certified Safety
In any installation, safety is paramount. The DM36 has been rigorously tested and is both HETAS approved and CE marked. This ensures that the product meets strict industry standards, offering peace of mind that your chimney system is not only efficient but also safe to use.

Installation Best Practices
Installing a chimney flue block might sound daunting, but with the proper guidelines, you can achieve a secure installation without hassle. Always start by checking the measurements, ensuring that the DM36 fits perfectly within your existing chimney casing. Maintain the critical distance requirements – 0mm on straights and 38mm on offsets. This not only protects your property but also preserves the product warranty. If in doubt, consulting a professional installer is highly recommended to maximise safety and efficiency.
Accessorising Your Chimney System
While the DM36 is fully capable on its own, there are optional accessories available that can further enhance your chimney’s performance. Consider exploring additional flue liners, insulation kits, and custom adapters to tailor your installation to your specific needs. These accessories can optimise thermal efficiency and extend the longevity of your chimney system, ensuring an even more robust and reliable performance over the years.

Compatibility Issues
