    Have you considered an outside air kit for your chimney? It is an optional field-installed accessory that is highly recommended. This feature is designed to reduce the results of continued negative pressure within the chimney. The Majestic CAK4A Chimney Air Kit is what you need if you have a 300 series chimney system. This chimney air kit only weighs 5 pounds. Installing it is a very simple process, but its effectiveness can lengthen the life of your chimney. When installing the Majestic CAK4A Chimney Air Kit, use the shortest duct; this allows for the best performance of the outside air kit.
