Installation Guidelines
Before installation, it is crucial to prepare by reading the complete installation manual. Here are the key steps for a successful assembly:

2. Assembly: Start at the base of your chimney system or appliance, interlocking each pipe section with the twist-lock mechanism. Secure each connection with the provided locking band to prevent accidental disengagement.
3. Safety Check: After the installation is complete, check that there is a continuous 50mm gap between the pipe and any combustible materials. Re-inspect the joints for any signs of looseness or misalignment.
Important Tip: Always adhere to local building regulations and consider professional installation support if you are not confident in executing the installation yourself. This ensures both the longevity of the flue system and the safety of your property.
