With ½” wrench, turn spud down or clockwiseuntil snug (approximately 2 ½ turns). This re-stricts the flow of gas through spud to that al-lowed only by the hollow LP metering pin. Donot overtighten.Figure 103.Lower main top and apply gas to check for proper flamesize. Flame should be steady with approximately ½”blue inner cones and no yellow or orange tips.Figure 11Proper Air AdjustmentIf air shutter is adjusted so that too much air flowsinto the burner, the flame will appear unsteady,possibly not burning all the way around and will benoisy (like a blow torch).C. Readjust the “LOW” Setting Surface BurnerValve1. Turn control to LITE until burner ignites.2. Quickly turn knob down to LOWEST SETTING.3. If burner goes out, readjust valve as describedin “Adjust the LOW Setting Surface BurnerValve” from Page .D. Air Adjustment ShutterApply gas to the burner and adjust air shutter onburner venturi tube to proper flame. For LP gas,the air shutter is generally left completely open.Figure 12The air adjustment for each burner is located atthe open end of the venturi tube and sits on thehood of the valve. The shutter is held in place byfriction fit.Air ShutterPinNat.HoodL.P.SpudNatural GasIncrease GasIncrease FlameSize(Pre-Set at Factoryfor Natural Gas)L.P.
