Connect gas lines
Procedure
1. Remove the plug from the 1/16-in sample vent tubing marked

that is located
on the flow panel assembly. Depending on your configuration, there may also be a
second sample vent marked
SV2
. If so, remove its plug as well.

B. Measure vent
•
If desired, connect the sample vent lines to an external, ambient pressure vent. If
the vent line is terminated in an area exposed to wind, protect the exposed vent
with a metal shield.
•
Use
¼
-in or
⅜
-in tubing for vent lines longer than 10 ft (3.05 m).
NOTICE
Do not discard the vent line plugs. They are useful when leak-checking the gas
chromatograph (GC) and its sample or gas line connections.
At this stage in the installation, the measure vent (
MV
) lines (labeled on the side of
the GC) should remain plugged until the GC has been checked for leaks. For regular
operation, however, the
MV
lines must be unplugged.
2. Connect the carrier gas to the GC.
The carrier gas inlet is labeled
Carrier In
and is a
¼
-in T-fitting.
