Looks Like you are planning on NG. Just a word of caution... size your supply pipe accordingly. My dryer has 1/2in pipe... if I run it 60ft to the garage, I would not be able to supply the gas flow to support the burners you are looking at. I would have to run bigger pipe (3/4 or 1inch I guestimate, but there are tables online to figure out how many btu for length and pipe diameter).
Keep in mind you may be running two burners at the same time, so size the pipe for that. (So if two burner at 90,000 btu, you will need to supply enough gas for 180000 btu)
