Installation must always be carried out from the top of the chimney to ensure that the liner is fed properly and securely. Begin by testing a small section of the liner to confirm it fits down your chimney with ease. Secure a piece of string to the Nose Cone (a separate accessory available to complement your flue liner) and attach it to the top of the liner. Pull the liner gently down the chimney while continuously feeding it from above. It is crucial to check the compatibility of your chimney structure and maintain proper clearances as specified in the installation guide. Always follow manufacturer recommendations and seek professional advice if uncertain about any step.
