I run 2-20 tip jet burners. I plumbed to my setup with 3/4" pipe, to a ball valve. I bought a 10' piece of flex line that is 3/4" and had quick disconnects. I plumed to the burners with hard pipe, 3/4". They reduce to 1/2" at the jet burner. NG doesn't put out the BTU the same as propane. I never used propane, the thought of tanks going empty didn't appeal to me. I love having NG and turning the valve. I just control my flame with a gas ball valve. I will say the flex gas line is pricey.
