Damper fits smoke chamber
Photo shows the steel damper that is used with the Firecast. The actual exit size is only 40 square inches. This reduced damper size allows for the installation of an 8" Round Stainless Flue. With regards to restoration situations, the ability to install a Class A Flue or a Rigid/flex flue liner to the Firecast is a real advantage. With upper chimney damage, the damaged or non code complying masonry chimney can be simply removed and an updated Class A Stainless can be installed.
