2. Connect the atmospheric vents to a vent line of at least
⅜
''
diameter that is routed to the atmosphere in a safe area to
ensure there is no back-pressure created on the vents.
NOTE:
The flows out of the vents are:
Sample Vent
– 10 to 50 cc/min of sample gas for approximately
3/12
minutes of the 4 minute cycle.
Measure vent
–Continuous flow of less than 10 cc/min of carrier
gas and 10 cc of sample gas per analysis cycle.
Sample Bypass
– Continuous flow of 150 to 200 cc/min of sample
gas.

Connect the gas lines
1. Using the tubing supplied with the sample system, connect the
stream, actuation, and calibration gases from the sample plate
to the manifold block (as shown).
3. Open the carrier gas bottle valves and set the regulator to
90 PSIG (6.2 BarG).
4. Open the calibration gas bottle valves and set to
15 PSIG (1 BarG).
5. Open the sample probe valves and set the sample pressure to
20 PSIG (1.4 BarG).
6. Leak check all lines with liquid leak-check solution.
7. Open the sample and calibration valves on the sample panel
and leak-check up to the fittings on the 370XA inlet manifold.
