Installation Instructions: 1. Measure the required flue length between 500mm and 850mm to ensure a precise fit for your appliance setup. 2. Assemble the adjustable pipe sections using the secure 8-barbed twist-lock mechanism. Ensure that each section clicks into place firmly. 3. Maintain a minimum clearance of 50mm from any combustible materials, such as wood or plasterboard, throughout the installation process. 4. Insert the provided insulating material into the annulus once the pipe is adjusted to the desired length. This step is crucial for maximising heat retention and ensuring the safety of the system. 5. Secure the assembled pipe with the locking band to prevent accidental disassembly. 6. Finally, carry out a thorough inspection to confirm that the system complies with HETAS standards. If in doubt, seek professional assistance to verify that all installation criteria have been met. Warning: Always double-check the clearance requirements and ensure that the pipe is installed in a well-ventilated area to prevent overheating.
