• Ensure all components are inspected and clean before beginning installation. • Begin by positioning the lower section of the pipe, ensuring that a minimum 50mm clearance from combustible materials is maintained at all interfaces. • Align the 8-barbed twist lock connectors precisely to engage each component securely. The twist lock mechanism is designed to snap into place; do not force the connection. • Once the components are connected, secure them with the provided locking band to prevent accidental disassembly. • Double-check the alignment and clearance, verifying that your installation complies with local building regulations. • If any doubts or obstructions arise, consult the National Flues installation manual or contact a certified installer for assistance.
