Key Features and Benefits
The DM36 is not just another casing and soot door; it is a purpose-built component designed to handle the rigours of modern heating systems.

Additionally, the innovative design that separates the inner and outer layers not only allows for thermal expansion but also helps in preventing common issues such as cracking and leaks.

The use of pumice—a naturally efficient insulation material—ensures rapid heat build-up and consistent temperature maintenance. This means that your heating appliance will perform at its best without the risk of overheating adjacent structures. The regulatory approvals (HETAS and CE) further testify to its reliability and safety, making it a trusted choice among industry professionals.

2. Secure Fitting: Follow the guide to affix the casing securely, ensuring that the double wall system is correctly aligned and positioned.
3. Safety Measures: Make certain that the installation adheres to local fire safety regulations and standards. If in doubt, contact a qualified installer for assistance.
It is also worth noting that while the basic DM36 system provides exceptional performance, customers often benefit from exploring a range of optional accessories. These include additional insulation panels, upgraded soot door components, and custom mounting brackets, each designed to address further needs or unique installation challenges.
