When a wood burning appliance exhausts into a masonry chimney, the exhaust gases expand to fill the chimney. When they expand the gases cool. When the gases cool, they condensate in the form of creosote onto the walls of your terracotta clay flues. creosote is a flammable, gummy, tarry, substance that is hard to clean and when heated can be ignited and cause a chimney fire. Smoke naturally drafts better in a cylinder. It travels up in a tornadic fashion up your chimney. If the gases are properly vented, the risk of a chimney fire is significantly lowered. Chimney repair work is expensive. A properly lined chimney increases the efficiency of the chimney by keeping the exhaust gases from the appliance moving at the proper rate. This keeps your appliance working at its best performance.

WARNING: Installing a chimney liner or chimney liner components in any space other than a code-compliant masonry chimney is extremely dangerous, creates a severe fire hazard and voids any and all warranties. To ensure safety and compliance with building codes, the liner type and material must match the approved appliance and fuel type, and installation must only be performed by a licensed or certified installation professional. See the installation for further details.
