The Chim-A-Lator is operated by a convenient lever installed on the side wall of the fireplace.View: With Thumbnails | Without Thumbnails
The lever has six positions so you can precisely control the amount of draft. That means more heat when the fireplace is in use. The Chim-A-Lator mounts directly to the flue tile and therefore requires that the flue tile extends at least 1.25" above the crown. The Chim-A-Lator is 11" from base to lid and comes equipped with a 30' cable. A 50' cable is also available. Comes with a 7' cable shield to protect the cable at rub points in the chimney. Comes with a lifetime warranty.
