FlameCheck Safety System
The correct positioning of the thermocouple probe is
shown in Figure 23. The tip of the probe is positioned in
the flame. The probe senses the heat from the Front
burner, and activates the FlameCheck valve. The valve
allows the gas to flow into the Front burner. If the Front
burner should go out for any reason, the thermocouple
probe will cool off, thereby closing the FlameCheck valve,
which stops the gas flow to the burners.
If the FlameCheck Safety System should fail to operate,
contact Weber-Stephen Customer Service.
