Gary-

There was recent thread on this issue.,,,but I had a hard time finding
it

subject was

gas pipe size

Ed Pawlowski posted a link to very useful document

http://www.newark.org/externals/a6/f...257dbb1869.pdf

Not knowing the exact layout of your gas lines & appliances...I would
say that a 1/2" in your situation is probably ok but close.
depends on what else is on that gas line & whether is was running at
the time of your "test". Water heater? Furnace?

But in any case you should follow the example in the document &
determine whether your gas distribution system is up to its task.
