It may be possible to use an existing chimney, but it is important that your chimney is inspected first, as it may need cleaning. We offer a chimney inspection and reporting service as well as chimney cleaning and chimney lining services.
If it is clean and suitable, then we can just add a connector to the flue outlet at the back or top of stove and then attach a flexible flue liner to this which can be run up the chimney and place a cowl on top. This flue liner should be appropriately sized to the internal diameter of the flue outlet on the stove. We supply flexible flue liner in any lengths you require, in a variety of internal diameters. We can recommend the flue that is appropriate for you.
