^ Yep. It took the plumber about ~40 minutes or so to hook it up. It took him a bit longer since he decided to add fastener to secure the gas line better to the wall. FWIW, I did have all the parts that were needed (save for couple fitting which the plumber had on hand) and the gas shut-off valve was located within the required distance.
Even if you needed to route a new gas line to your dyer, I can't imagine it taking too long since we had to do that for our gas stove (we already had gas in house, but not gas connection for stove in kitchen) and it was done in couple of hours.
