How to Use the Ash Dump As a Gas Line Chase

The ash dump provides a path from the inside of the fireplace to the basement of the building where the gas main is located. Consult with you local building authority to see if this is allowed in your area. Also inquire about what specific rules are involved with running a gas line in this manner.
