What is the proper gas pressure leading into my Samsung model DV457GVGSGR gas dryer? The Gas Requirements section of the installation manual doesn't specify pressure.
I found this in a google search, but the page is now missing (goes to 404 error). The text snipped seems to recommend 3.5 to 5 inches of water column. Is that correct?
Can I damage my dryer by sending 2 PSIG of gas pressure without a regulator? How much should I send to the dryer?
5" WC is a reasonable pressure which is about 0.18 PSI. There should be a sticker on the dryer that will say what the max inlet pressure.
Sending 2PSI without a regulator will likely damage the dryer or not have it work correctly. It'll probably blow the flame out and never dry your clothes.
Nominal line pressure after your gas meter should be "around 7 inches of water column (WC) or re-stating this in equivalent measure, that's 14.9 millibars or 1743 Pascals or Pa, or about 0.25 psi (pounds per square inch) or about 4 ounces of pressure per square inch." If you are seeing 2 psi, call your utility provider (may not be the same as your NG supplier) and request they come check the function of the pressure regulator supplying your meter.
