Testing Gas PressureProper gas pressure provides a consistent flow of gasto the appliance and is instrumental in checking forgas leaks. There are two pressure test points on thefront of the stove control valve where test gauge connectionsare made. See Fig. 20. Gauge connectionsare identified by:• E for inlet or supply pressure ( the amount of gascoming to the valve.)• A for manifold pressure (the amount of gas that iscoming out of the valve to the burner.)The line must be disconnected from the gas supplyline by closing the main supply manual gas shutoffvalve (gas cock) during any pressure testing of thegas supply piping system that is equal to or exceedspressures of 1/2 psig (3.5 kPa).Manifold PressureMINMAXNatural Gas: 1.6 WC (0.398 kPa) 3.5 WC (.87 kPa)Propane: 6.4 WC (1.59 kPa) 10.0 WC (2.48 kPa)ALWAYS TEST PRESSURES WITH VALVE REGULATORCONTROL AT THE HIGHEST SETTING.Symptoms of incorrect gas pressure include:Insufficient gas pressure:• Small pilot flame which can result in insufficientmillivolts.• Little variation in flame picture between HI and LOregulator settings.• Insufficient gas to support more than one appliancecausing nuisance outages or gas surges.Excessive gas pressure:• Permanent damage to valve causing complete applianceshut down.• Too large a pilot flame resulting in overheating ofthe power generator and consequent shut down.• Sooting due to impingement and/or incorrect fuelto air mix.AEManifoldInletFigure 20.
