Once fitted, remove the nose cone, cut the liner to the appropriate length, and secure it using a clamp plate. Ensure the liner projects 75mm above the clamp plate for terminal attachment.

Secure both ends of the flue liner to a register plate or a flue pipe as required. Finally, apply a suitable cement for sealing and weatherproofing.**Maintenance:** It is advisable to sweep and maintain chimneys serving gas and oil appliances regularly, at least once a year, to ensure optimal performance and safety.
