The chimney liner is the ultimate solution to the problems that plague most chimneys. Modern stainless steel provides air tight and water tight barrier that seals in gases and creosote. Underwriters Laboratory declared that flex systems excel standards for chimney safety and can even withstand a chimney fire and still maintain structural integrity.

This system is to be installed in all new or existing masonry chimneys that are used for the natural draft venting of gas, liquid, and solid fuel fired residential type appliances and masonry fireplaces. While extreme care has been taken to make the system as safe as possible, proper installation, operation and maintenance should be followed.

316TI Stainless Steel is the Best Stainless Steel for Chimney Liners
316TI is a stainless steel alloy with a small amount of titanium added. It’s make-up allows it to resist acids and the stresses of hot and cold cycles. It can be used with solid fuels (wood, coal and pellet), gas and oil. It can withstand temperatures up to 2100 degrees.

If your masonry chimney is suffering from problems due to a newer appliance, the solution is to install a stainless steel chimney liner.
