Installation Guidance
Installing a chimney system component can seem daunting, but the Sflue Adjustable Pipe is designed with simplicity in mind. Follow these steps to ensure a smooth installation process:
Pre-Installation Check
Before beginning the installation, it is important to review the installation manual thoroughly. Ensure you have all supplementary support components as the pipe must be used in combination with them for vertical applications. Verify that the installation area maintains a minimum 50mm distance from any combustible materials, ensuring safety.
Step-by-Step Installation
1. Preparation: Clean the chimney system area and measure to confirm that the pipe will fit securely into place. Always wear appropriate protective gear during installation.
2. Fitting the Pipe: Align the slip section with your chimney system. Use the 8-barbed twist lock system to securely join the sections. Make sure the twist lock mechanism is fully engaged.
3. Securing the Sections: Once in place, use the provided locking band to further secure the connection. This additional step is vital, especially in vertical installations, to prevent any accidental disconnections.
4. Insulation Check: Confirm that all insulation segments, made of high-density compressed rockwool, are properly aligned. This is crucial for maximising thermal efficiency and providing a safe operating environment.
5. Final Inspection: Finally, conduct an overall inspection of the installation to ensure that every component is correctly connected and that the mandatory 50mm clearance from combustible materials is maintained.
