Thank you for installing one of our Ultraflex / Twinflex Pro Flexible liners. We hope you enjoy many years of warmth and comfort from your installation.

To prolong the life of your appliance please ask your Installer about moisture metres, stove thermometers and chimney cleaning logs.

Please ensure that all your fuel burning appliances are serviced annually and that all flues, vents and chimneys are unblocked. It is recommended that you fit an audible carbon monoxide alarm - these are available from online store here or from registered HETAS Installers.

To register your installed liner, you will need your sales order number, HETAS installers details of your local building control. You cannot proceed with the registration process without this important information.
