The selected gas introduced into the sample path of the cell is vented
through the gas outlet fitting.
If it is desirable to carry the outlet gas to an area remote from the
analyzer to vent it, the following precautions must be observed in vent line
installation:
a) The vent line should be constructed of tubing of sufficient
diameter so that no appreciable back pressure resulting from
restricted flow is experienced by the analyzer.
b) The sample line must be vented into an area where the ambient
pressure is the same as that of the analyzer.
c) The ambient pressure in the vent area must undergo no more
than normal barometric pressure changes.
d) The vent line must be installed so that water cannot accumulate
in it.
