Hi, I was looking at using a Gas Valve Key like you would use on a fireplace for my BBQ Island so I do not have to reach under the Island to shut the gas off when we are not using it. The problem is I have a Firemagic Elite 50 Grill and the only gas valve keys I have been able to find are for 1/2" pipe and say they can only support up to like 80k BTU through them. The Firemagic grill draws more than that so I am concerned I would be choking it off. Anyone ever seen a 3/4" valve like this? Please let me know. Thanks!!
