Gas Valve pressure test [ 5 Answers ] I just ordered a new gas valve for my fireplace. I damaged my old one by blowing compressed air into it to remove spiders that had found their way in through the gas orifice to the burner. Question: how do I test the water column pressure on the new valve, or do I assume it already comes pre-set. Don't, for example, use a 90 PSI gauge to test a 3 PSI gas system; it's not designed to be sufficiently accurate for the test. The reason people say test at minimum 20% on the gauge is the NFPA 54 fuel gas code §8.1.4.1 says shall have a range such that the highest end of the scale is not greater than 5 times the test pressure.
When testing for leaks, there will be some natural rises and drops in the pressure of the gas line. It is common for standard gas line inspections to require lines hold three times their working pressure load for at least 30 minutes. Typically, if the gas line loses approximately 2 psi from a test of 20 psi on the line, the lines are acceptable. It's a natural gas grill. And by no gas in the pipes, I meant that the new natural gas lines haven't been hooked up to the meter yet. I was mostly worried about the possibility of a pinprick hole that I couldn't see in the hose. The hose looks great, but there's always that nagging voice of concern.
