3.4.2.3. Input Gas Venting 
The span gas, zero air supply and sample gas  line MUST be vented in order to ensure that the gases input do 
not exceed the maximum inlet pressure of the analyzer as well as to prevent back diffusion and pressure effects. 
These vents should be: 
  At least 0.2m long;  
  No more than 2m long and;  
  Vented outside the shelter or immediate area surrounding the instrument. 
3.4.2.4. Exhaust Outlet   
Attach an exhaust line to the analyzer’s EXHAUST outlet fitting.  The exhaust line should be: 
  PTEF tubing; minimum O.D  ¼”; 
  A maximum of 10 meters long; 
  Vented outside the M300E/EM Analyzer’s enclosure. 
 
NOTE  
Once the appropriate pneumatic connections have been made, check all pneumatic fittings for leaks 
using the procedures defined in Section 12.3.3.
