FLAME ADJUSTMENT TIPS
Your PGS burner has been designed to operate efficiently under widely varying operating conditions and is adjusted at the factory for proper operation so no adjustments should be required. Occasionally, vibration during transport or variations in local fuels and gas pressure, altitude, or other external conditions might require minor burner adjustments. Sometimes your burner will burn differently if your propane cylinder has been recently filled or it is near empty. Sometimes air will need to be purged from your natural gas line.
A qualified technician should make burner adjustments at the time of installation. Extreme care should be exercised if adjustments are required after installation. If you need to inspect and adjust burners while unit is operating:
Carefully remove rock grates, cooking grids, and rock from bottom casting. Burner adjustments can be best performed in low light and in
Inspect the burner when it is on low. Flames should be mostly blue and stable. The flame tips will be yellow at the ends and this is normal. When you reinstall the rock grates the burner flames impinging on the rock grates will also cause the flame pattern to appear more yellow, this is normal and does not in any way affect the performance of your grill. A burner in an outdoor appliance operates in a different environment than an indoor appliance burner or flame and as a result will visually look different.
If you see the flames lifting from the burner, or only parts of the burner are burning, or if you hear excessive noise from the burner, please check the following: valve/orifice engagement in the venturis, that the burner is level in the casting, and also check burner tubes to be certain they are not obstructed with debris or spider webs. These conditions will more often be the case than the burner being out of adjustment. If you feel that you do need to adjust the burners please follow directions below when burners are cool to the touch:
1.Disconnect ignition wire at module. Disengage your burner by unclipping it from the rear and lifting forward and up.
2.At the end of each of the burner venturis you will see an air mixer secured by a small setscrew. When the screw is loosen the air shutter can be rotated to allow more or less air.
3.If the flame is extremely yellow this indicates the burner is getting insufficient air. Turn the air mixer to
the open position to allow more air to the burner. Tighten screw to insure mixer stays in this position.
4.If the flame is noisy and tends to lift away from the burner tube there is too much air being fed to the burner. Turn the air mixer to reduce the opening and air volume to the burner. Tighten screw to insure air mixture does not move.
5.Reinstall burner and light as normal and inspect flame. If burner requires additional adjustment repeat above procedure. There is not a significant degree of adjustment required to these burners.
Differences in altitude, operating conditions, weather conditions, gas pressures, odorants and stabilizers used in both natural gas and propane will often cause burners to burn differently. As long as you are getting good ignition, even cooking performance, and the burner flame is blue with yellow tips and operating consistently, you should not have to adjust the burners. If you have any additional questions in this area, you should contact your local natural gas or propane utility or contact your authorized PGS dealer or distributor.
