PROPER FLAME PATTERN
BISB245
Spiders and insects are attracted to the smell of propane and natural gas. The nest or web will cause the burner to burn with a
soft yellow or orange flame. To clean the inside of the burner, remove the cap and use a soft wire brush to remove any debris
from the burner ports. Do not enlarge the ports. The burner caps are pocelain enamel and can be cleaned with warm soapy
water, rinse and dry thoroughly before re-installing.
BISZ300
Spiders and insects are attracted to the smell of propane and natural gas. The nest or web will cause the burner to burn with a
soft yellow or orange flame or cause a fire (flashback) at the air shutter underneath the control panel. To clean the inside of the
burner, it must be removed from the gas grill. Lift the back of the burner upwards to remove. Use a flexible venturi tube cleaning
brush to clean out the inside of the burner. Shake any loose debris out of the burner, through the gas inlet. Check also that the
valve orifices are clean. Do not enlarge the orifices. Re-install the burner.

It is very important when re-installing the burner after
cleaning that the valve/orifice enters the burner tube before
lighting your gas grill. If the valve is not inside the burner
tube a fire or explosion could occur.
