The appliance itself usually calls for a gas pressure of 3.5 inches of water column at the burner and that is set by the internal regulator. PSIG or PSI = pounds of pressure per square inch (gauge pressure), WC or "WC = equivalent pressure expressed as inches of water column. One can imagine that the manufacturer's person answering the phone has been told that only ZERO LIABILITY is acceptable. The propane regulator does just that—regulates the flow of gas to the grill. This flow out of the regulator causes gas pressure in the regulator to drop, thus reducing gas pressure against the rubber diaphragm and spring, allowing the spring to push the diaphragm downwards, opening the gas valve at the valve seat on the gas inlet end of the regulator.
