How a gas grill works: A gas grill works much the same as a gas stove in the kitchen. Gas is propelled through a small gas line from a portable propane tank, usually located on the side of the grill, and an igniter mechanism produces the spark which lights the gas which flows through the grills rows of burner.
General checking while lighting a gas grill:
1.Check all connections concerning the flow of propane.
2.Make sure that the propane tank is full by checking the guide which is usually located on the side of the grill. A diagram which measures the propane level based on the tank’s weight can tell if it’s time to refill.
3.Check the knob on the top of the propane tank, which attaches the hose through which the gas flows. Turn this knob clockwise to create a seal. if gas escapes, you may not be able to smell it, so check this first.
4.Check the open/close valve on top of the propane tank. Turn the knob more to the right to release more gas while igniting. After the grill is lit, adjust the flame with the knobs on top of the range, but the valve needs to be in the open position while lighting.
5. Return the gas to the closed position. Look inside the grill.There will be small rows of metal rods with small holes in them. These are the burners, and they must be kept free of grease and food particles. A small can of compressed air may come in handy for this task. Simply aim a blast of air at the burners, after making sure that the gas is shut off and no flame is burning inside the grill. Give a quick blast over the burners to remove any particles which may be clogging the gas flow.
6.Try to light the grill manually. Dampness or extreme cold may render the igniter temporarily out of service, and this is a quick and easy solution. Located on the bottom front panel, usually in the general area of the igniter switch, there will be a small hole. Using a propane barbeque lighter, which is really just a lighter with a long stem attached, light it manually. First turn the valve on the top of the propane tank to the open position. Inserting the end of the lighter into the hole, turn the knob on the control range to the Light position, and ignite the lighter.The grill should light quickly. Remove the lighter from the hole and adjust the flame.
7.If the above methods have not produced results,give the grill for servicing by a professional. Keeping the grill clean and the catch trays beneath the grill empty will help to ensure trouble free operation. The grill should be lightly cleaned after each use, and always check to make sure all valves have been closed prior to putting the grill away. After using, let the grill cool down, clean, and cover the grill with a fireproof BBQ cover between uses.
Problems and Trouble shooting:.
Gas grill barbecue does not get hot enough and will only stay lit for a short time
1.First,check to see that you are not out of propane fuel.
2.Another cause could be that the excess flow regulator on the gas grill has been activated. This could be a result of a leak in the system or a burner valve being open when the cylinder was opened.
3.In the case of a leak, perform a leak test by brushing soapy water on all connections. A leak will cause the soapy water to bubble.
4.If the burner valve on the gas grill was open when the cylinder was opened, turn the valve to the off position, close the valve on the propane cylinder, and disconnect the regulator from the tank. Then, reconnect the regulator to the tank, slowly open the valve on the tank, and then turn a main burner valve to the lighting position as done normally.
Although not considered normal, uneven heat with the gas grill could be caused by a blockage in the burner venturi tubes. It is possible for small insects or debris to get inside the venturi tubes of the burner. Any blockage inside these tubes could cause uneven heat. Cleaning instructions for gas grills can be found in the owner's manual.

Yellow flame in the gas grill and how to fix itA yellow flame in a gas grill can be caused by one of two things: an improper air/propane mixture or a dirty burner.
1.Try adjusting the air vent behind the control knob on the gas grill to allow more or less air to be mixed with the propane and will generally result in a blue flame. (A blue flame with yellow tips is optimal for grilling.)
2.If adjusting the air vent yields no results,try to clean out the burner. Even brand new burners can be clogged, usually with dust or other particles from storage or transit.
A couple of blasts with an air compressor through the gas grill's air vent should be enough flush out anything that may be clogging the burner.
3.If there is no air compressor handy a garden hose may be used instead.
No heat out of the gas grill burner even when the gas grill is turned on highThe gas grill is operating in low flow mode. Low flow mode is a safety feature activated when the regulator thinks there is a propane leak somewhere in the gas grill.
1.To correct the problem, double check that the propane hose has been attached to the stove with a wrench, not just finger tight. Confirm that all control knobs are turned to the "off" position.
2.Remove the hose from the propane tank and wait approximately 30 seconds to reset the regulator. Reconnect the hose to the propane tank on the gas grill and slowly turn the propane tank on, allowing the propane to fill the stove manifold.
3.Next, turn the control knob to "warm" and relight the burner on the gas grill. After the burner has been lit, turn the propane tank on fully. If there is still a low flame,there may be a propane leak.
How to check for gas leaks on gas grills?To test for a leak on the propane gas grill, pour soapy water over the valves, manifold, and hose. Turn on the propane tank and watch for bubbles.
