the screens, remove the burners for cleaning the screens.
Brush the Spider/Insect screens lightly with a soft bristle brush (i.e. an old toothbrush).
ƽ CAUTION: Do not clean the Spider/Insect screens with hard
or sharp tools. Do not dislodge the Spider/Insect screens or
enlarge the screen openings.
Lightly tap the burner to get debris and dirt out of the burner tube. Once the Spider/
Insect screens and burners are clean replace the burners.
If the Spider/Insect screen becomes damaged or cannot be cleaned, please contact the
