B. Chimney

•Ensure chimney is constructed of non-combustible materials.

•Ensure chimney is clean and in good working order.

This access hole must be plugged with non-combustible insulation after the gas supply line has been installed.

•Install gas line into firebox cavity.

•Check local codes and gas line sizing requirements following NFPA51. See Section 8.
