Installation of the 125mm Flue Liner is straightforward yet requires adherence to safety standards. Begin at the top of the chimney: secure a string to a Nose Cone (available as an optional accessory) and attach it to the liner. Carefully pull the liner down while an assistant feeds it from the top. Ensure the liner is firmly fixed with a clamp plate and use a suitable adhesive cement to seal joints for weatherproofing, checking that all components are in good condition. Avoid using damaged chimney pots and consider removing them if not using a suspended cowl. For optimal installation, always follow manufacturer guidelines and safety precautions.
