Additional Safety Features:
• 8-barbed twist lock mechanism assures a secure, tight fit
• Mandatory 50mm clearance from combustible materials enhances fire safety

This compliance with industry standards makes the Sflue Black pipe an excellent choice for homeowners who prioritise safety without compromising on performance.
Installation Guidance
Installing the Sflue Black 1200mm Pipe is straightforward, thanks to its intuitive design. The twist lock mechanism is engineered to simplify the assembly process, making it accessible even to those with limited technical expertise. However, it is essential to follow the recommended installation guidelines to ensure a secure and compliant setup.
Installation Process:
1. Begin by inspecting all components to ensure there is no damage or debris.
2. Position the lower section of the pipe, ensuring a 50mm clearance from all combustible materials.
3. Align the twist lock connectors meticulously and engage them by twisting until you hear a click, indicating a secure connection.
4. Secure the joined sections using the provided locking band to enhance stability.
5. Conduct a thorough final check to confirm that the entire setup adheres to the installation requirements.
Attention to detail during installation will not only ensure the longevity of your flue system but will also help maintain the high efficiency and safety standards promised by National Flues.
