Care and Maintenance
PROTECTION OF INFRARED BURNERS
The burners of your grill are designed to provide a long life of satisfactory performance. However,
there are steps you must take to prevent cracking of the burner's ceramic surfaces, which will cause
the burners to malfunction. The following are the most common causes of cracks and the steps you
must take to avoid them. Damage caused by failure to follow these steps is not covered by
your grill warranty.
IMPACT WITH HARD OBJECTS -
Never allow hard objects to strike the ceramic. You should
take particular care when inserting or removing cooking grids and accessories into or from the grill. If
objects such as these fall onto ceramic, it is likely to crack the ceramic.
IMPAIRED VENTILATION OF HOT AIR FROM GRILL -
In order for the burners to function
properly, hot air created by the burners must have a way to escape, the burners may become
deprived of oxygen, causing them to backfire, especially if the burner output is set at HIGH. If this
occurs repeatedly, the burners may crack. This is the reason your grill was designed with ventilation
louvers. These design features give the hot air an escape route. Accordingly, never operate your grill
with very little or no open space at the cooking surface (the cooking grids provide sufficient space).
Also, never cover the ventilation louvers with foil or other materials that prevent air flow. Specifically,
do not cover the entire surface with foil, a large pan, etc.
GENERAL MAINTENANCE
- Keep outdoor cooking gas appliance area clear and free from combustible materials, gasoline and
other flammable vapors and liquids.
- Do not obstruct the flow of combustion and ventilation air.
- Keep the ventilation openings of the cylinder enclosure free and clear from debris.
- Visually check the burners
Normal: Soft blue flames
O u t o f A d j u s t m e n t :
Hard blue
flames- too much air
Poor Combustion:

your warranty.
INFRARED BURNER CLEANING
After each use, it is necessary to burn the bottom infrared
burner with the hood open for at least five minutes to vaporize
any food drippings or particles. Failure to perform this step will
damage the burner. It may occasionally be necessary to brush,
blow, or vacuum accumulated ash from the burner surface. Do
so carefully and only when the burner is cool.
