good input folks, thanks.
As for running gas lines, it is easier than one would expect. I used Gastite (brand name) fittings and normal old 3/4" pipe fitting to extend my furnace gas line across a wall to my the mentioned tankless water heater. It was a couple more fittings, about $50 total and I had a piece of gastite pipe left over from the tankless install to get this done. I have not connected the fittings yet, but having done it once already, the initimidation factor of blowing up my dwelling is gone.
I particularly like the used angle. Living in the Portland, OR area, the house flipping frenzy has been pretty rampant and finding a good used gas dryer will probably save me more than a few dollars. And I have no intention of removing the existing 220VAC dryer connection because I have a welder that I run from it. So the next folks that buy the house down the line will have both options available to them.
I'll probably start on it this weekend. This is a uniquely small project in my house for I am currently tearing out my 500sqft deck and putting in a similar sized concrete patio. Concrete stamping is expensive, but the added value to the house will exceed the cost, so that's good.
Thanks again folks,
