CALIFORNIA PROPOSITION 65 - WARNING
The burning of gas cooking fuel generates some by
products that are on the list of substances which are
known by the State of California to cause cancer or
reproductive harm. California law requires businesses to
warn customers of potential exposure to such
substances. To minimize exposure to these substances,
always operate this unit according to the use and care
manual, ensuring you provide good ventilation when
cooking with gas.
INSECT WARNING!
Spiders and insects can nest in the burners of this and
any other grill, and cause the gas to flow from the front of
the burner. This is a very dangerous condition which can
cause a fire to occur behind the valve panel, thereby
damaging the grill and making it unsafe to operate.
Inspect the grill twice a year or immediately if any
symptoms appear.
