40m 6″ 904 Flexible Chimney Liner

According to Irish building regulations, 150mm flue can be used with bituminous coal, peat, seasoned timber, smokeless fuels, low volatile fuels such as oil or gas and wood pellets.

However, since 316 flexible liner was designed for and is tested with timber-based fuels, if you will be using bituminous coal, peat and smokeless fuel, we recommend you install 904 grade flexible liner instead. It is permitted to use oil, gas, seasoned timber and wood pellets with 316 grade flexible liner.

SHL 904 twinwall flexible flue liner is used to reline a chimney, normally a masonry or concrete built chimney.

40 meter lengths of 6″ diameter 904 twinwall flexible flue chimney liner are predominantly bought by companies or individuals operating in the trade. Existing trade customers who buy this product consist of chimney specialists, stove fitters / installers, builder merchant, hardware store and stove and fireplace shops.

Tradesmen and the professionals listed above will cut a 40 meter length of 6″ diameter 904 twinwall flexible flue chimney liner to the appropriate size and use it to install a stove in your home. Usually this stove is installed where a heat producing appliance had been installed previously because there is an existing chimney flue in place. 6″ diameter 904 twinwall flexible flue chimney liner is then used to reline this chimney.

After installing any length of 6″ diameter 904 twinwall flexible flue chimney liner in Ireland, the solid fuel burning stove or heat producing appliance is permitted to burn bituminous coal, peat and seasons timber, in addition to smokeless fuel or biomass wood pellets.
