An open flame, burners and other hot surfaces can present heat hazards that can
result in severe burns.
When operating a flame system, always operate your spectrometer with the flame
shield closed, the chimney in place, and the sample compartment front panel in
place.

chimney time to cool.

Keep your hands out of the sample compartment while a flame is burning.
WARNING
Hot Surface
The burner and flame compartment become extremely hot during instrument
operation and remain hot for some time after the instrument has been
switched off.
Allow the system time to cool before attempting to access the burner or
sample compartment components.
Always use protective gloves when removing a burner from the instrument.
