Flue Liners 316 Grade & 904 explained
What is the difference between 316L and 904L flue?
Which liner to choose? The difference is purely one of quality. The 904 grade is a higher grade of stainless steel suitable for Smokeless fuels then the 316 grade and is less likely over time to corrode from the inside.

904 Grade Flexi Liner

Regularly Sweeping of your Flue Liner
It is important that your flue is swept at least once a year and more often if the stove is used regularly throughout the year. If a sweep certificate is not kept for each year of use it will void the warranty.
