Installing A Stove Into A Chimney With Flexible Liner

 

This type of installation is favored by most installers. Flexible liner will ensure the life of your chimney is maintained. Flexible Liner heats up extremely quickly and ensures that the draught is up to a maximum very quickly. Flexible liner holds a 20 year guarantee against corrosion. At Woodburner Warehouse we only use 9FlexLiner04/904 grade of flexible liner which has a higher anti corrosion system to the the lesser quality flexible liner some of our competitors use.

Below we will explain exactly what items you will require in order to install your stove and what rules you must follow in order to comply with building regulations and to be completely safe.
