110 EL3000 CONTINUOUS GAS ANALYZERS
Ignition of the flame
12 The flame ignites automatically:
Depending on the number of ignition attempts, the flame can take up to
10 minutes to ignite.
Depending on the length of the combustible gas supply line, it is possi-
ble that not enough combustible gas is available to ignite the flame at
first during the initial start-up of the gas analyzer. In this case, the igni-
tion of the flame must be restarted in the Fidas Restart menu (see
page 116). The temperature of the flame is also displayed in this menu
option; the flame is regarded as "on" when the flame temperature is at
least 30 °C higher than the detector temperature.
The actual start-up of the gas analyzer is concluded with the ignition of
the flame.
NOTE
New and still unused sample gas lines and sampling probes can release hy-
drocarbons over a longer period after initial start-up. Therefore, it can take a
longer time until the measured value drift has reached an acceptable value.
