When installing natural gas, I was under the impression that the appliances would hook directly to the gas lines at 2psi but the inspector said that they are rated in water columns – here is the tag from my dryer: Converting w.c. to psi shows that 4 w.c. is around 0.144 psi and 10.5 w.c. is around .379 psi so I suppose the appliance is not supposed to take 2psi directly or 55 w.c. – but I have never heard of putting regulators at all the appliance connections and the inspector did say it is a new thing. I searched and it seems like this is the best regulator for the job, if I do in fact need one: MAXITROL 1/2″ IPS NATURAL GAS REGULATOR MODEL325-3L I believe the “L” model is the vent-limiting model that can be used indoors and it has some blue paint to show the difference. Specifications are as follows: Here is how I’m thinking about hooking it all up:
If you are installing natural gas lines you will need to determine the flow rate of certain appliances, like Gas Dryers. The line size of the natural gas pipe (or propane / LP piping) needs to be big enough, larger with distance, to allow for the specified flow rate from the manufacturer.
