To reduce the chance of FLASHBACK FIRE you must
clean the burner tubes as follows periodically in summer and fall, wherever spiders are active in your area, and if your grill has not been used for an extended period of time.
1.Turn all burner control knobs to the "OFF" position.
2.Turn the LP gas tank valve to the "OFF" position.
3.Disconnect the LP gas regulator assembly from the LP gas tank.
4.Remove the cooking grates, heat tents, and warming rack from the grill.
5.Remove the screw from the rear of each burner using a Phillips head screwdriver.
6.Carefully lift each burner up and away from the gas valve orifice.
7.Check and clean burner tubes for insects and insect nests. A dogged tube can lead to a fire beneath the grill.
8.Refer to FIGURE::[ and use one of these three
cleaning methods:
METHOD 1: Bend a stiff wire or wire coat hanger into a small hook as shown and run the
hook through the burner tube and inside the burner several times to remove debris.
METHOD 2: Use a bottle brush with a flexible
handle and run the brush through the burner tube and inside the burner several times to
remove any debris.
METHOD 3: Use an air hose to force air through each burner tube. The forced air should pass debris or obstructions through the burner and out the ports. Always wear eye protection if using this method.

Burner Ports
TO CLEAN BURNER TUBE,
Small insects, such as spiders, are able to access the
burner tubes. Sometimes they will build nests or spin webs. In either case, this can block or reduce the amount of gas flowing through the burner. You will usually see a smaller flame, or a flame that is mostly yellow rather than blue, coming from the burner when this happens. Other signs include the
gill not heating evenly, not reaching temperature, or burners not igniting. In cases with severe blockage, this can cause the flame to burn backwards, and outside of the burner tubes, which can cause damage to your grill and/or personal injury.
IMMEDIATELY SHUT OFF THE FLOW OF GAS AT
THE LP TANK OR NATURAL GAS VALVE SHOULD
THIS HAPPEN, Wait for the grill to cool, and then clean all burners.
Regardless of the burner cleaning procedure you use, we recommend you also complete the following steps to help prolong burner life.
1.Use a fiber pad or nylon brush to clean the entire outer surface of each burner until free of food residue and dirt.
2.Clean any clogged ports with a stiff wire, such as an open paper clip.
3.Inspect each burner for damage (cracks or holes) and if such damage is found, order and install a new burner. After installation, check to ensure that
the gas valve orifices are correctly placed inside the ends of the burner tubes. Also check the
position of your electrodes.
4.Never enlarge the burner ports during cleaning.
For safe operation ensure the gas valve assembly orifice is inside the burner tube before using your grill. See figure. If the orifice is not inside the burner tube, lighting the burner may cause explosion and /or fire resulting in serious bodily injury and/or property damage.

BURNER FLAMES
Always inspect the burner flame after lighting. A good flame should be primarily blue with a yellow tip and have a minimum amount of noise. Some yellow tips are OK if under one inch. New burners sometimes have oil residue, which will cause yellow flame when burning off. Variations in gas supply, altitude, weather, and other factors can all impact burner performance. Older grills can also show more yellow flame as food deposits, oils, and fats can build up.
