1. Before installation, ensure the installation area maintains a minimum of 50mm clearance from any combustible materials such as wood, plasterboard, or insulation. 2. Begin by assembling the telescopic sections, verifying that the adjustable pipe extends smoothly from 200mm to 325mm. 3. Connect each section using the 8-barbed twist-lock coupler system. Ensure that each twist-lock connection is fully engaged for a secure fit. 4. Use the included Locking Band to reinforce each connection, preventing accidental disconnection during operation. 5. Double-check all connections once assembled to ensure there are no loose fittings. Safety and efficiency are paramount. 6. Follow the manufacturer’s guidelines for the safe clearance around the flue, and secure any additional insulation if necessary. 7. Finally, conduct a safety inspection to guarantee that all installation standards are met before use.
