Chimney Lining Advice
Stainless steel liners are either designed for class 1 or class 2 applications. Class 1 liners are tested and certified for use with wood burning, multi fuel, and other solid fuel appliances. Class 2 stainless steel liners are designed for gas and oil boilers and fires. Each type of metal chimney liner has a designation code that shows (among other things) the tested maximum temperature and corrosion resistance.
