Frequently Asked Questions
Expert advice and support for your chimney and venting projects.
How do I determine the correct liner size for my chimney?
The correct size depends on the appliance's exhaust outlet diameter and the height of the chimney. Generally, you should match the liner diameter to the appliance's flue collar to ensure proper drafting and safety.
What is the difference between 304 and 316L stainless steel liners?
304L grade stainless steel is primarily used for wood-burning applications. 316L is a higher grade that contains molybdenum, making it more resistant to corrosion from oil, gas, and coal combustion.
