Do not use the flexible copper or stainless braided lines. Pop for the extra bucks and get the corrugated stainless lines. I would buy a new gas line flex connector as well. Read the instructions and use the provided di-electric (or buy new) connections. DO use yellow thread tape on the gas hard pipe connection to the gas valve, DO NOT use thread tape on flare connections.
A permit is required.
I would not call it hard, but it is easy to screw up a connection and end up with a leak a few months, or a few years, later.
