Natural Gas - supply size?

[motobrewer]

How are you guys sizing your natural gas supply? It seems that if you have 3x 200k BTU burners you would need a heck of a supply line.

If you're going to use all 3 at the same time, the supply would have to be big, but a lot depends on your run length. I have a 200k pool heater about 30' from the main supply. I had to run a 1" pipe according to the installation instructions. Could've gotten away with a smaller pipe if it had been closer.

I have 1/2". I can run 2 burners. 3 would be pushing it.

Well I ran 1" to the patio. I then have 1/2" from there to the burners.
