Spiders and small insects occasionally inhabit or make nests in the burner tubes, obstructing the gas flow. Sometimes this results in a type of fire in and around the gas tubes called “flashback”. To reduce the risk of flashback, the following procedure should be followed at least once a month or when your grill has not been used for an extended period of time.
Prior to starting this procedure, turn OFF all of the gas control knobs, shut off the fuel supply, and disconnect the fuel line.
- Remove burners from the grill by unscrewing the mounting bracket and carefully lifting each burner up and away from the gas valve orifice.
- Use a wire brush or stiff laundry brush to clean the outer surface of each burner to remove food residue and dirt. Clean any clogged ports with a stiff wire such as an opened paper clip.
- Inspect each burner for damage (cracks and holes). If any damage is found, discontinue grill usage until you replace the burner.
- After reinstalling the burners inspect the gas valve orifices for cleanliness and condition and the location of the ignitors. When you replace the burners, you will also need to re-attach the burner by screwing in the mounting bracket to the grill head.
