4.5 Connecting the gas line
This table provides an overview of the sample gas probe connections:
Connecting flange
DN65 / PN6
Sample gas input:
G3/4
Sample gas outlet:
GL14 (6 mm)
1)
Test gas connection (option):
Pipe Ø6
1)
Gasket inside diameter
Carefully and properly connect the sample gas line to the gas outlet of the glass pearl receptacle. Please see the drawing below
for the fundamental layout of the gas connection:
Glass
PTFE
CAUTION
Fragile
The glass pearl receptacle can break. Handle with care, do not drop.
Please note the correct position of the seal when connecting the gas lines. The seal consists of a silicone ring with a PTFE sleeve.
The PTFE side must face the glass thread.
The sample gas line must be braced and secured with the clamp.
Long sample gas lines may require additional support clamps along the way to the analysis system! Once all lines have been
connected and checked for leaks, carefully reinstall and secure the insulation.
WARNING
Gas emanation
Sample gas can be harmful to the health!
Check the lines for leaks.
4.5.1 Connecting the calibrating gas line (optional)
Connecting the calibrating gas line requires a Ø6 mm pipe fitting.
If the calibrating gas connection was ordered with check valve, a Ø6 mm pipe can be connected directly to the check valve.
4.5.2 Connecting the condensate line
Carefully and properly connect the condensate line to the outlet of the condensate pump. Check the line for leaks. Avoid contact
with the anti-freeze heating.
4.6 The glass pearl receptacle
The condensate output is located at the lower position of the glass pearl receptacle. It features a factory installed peristaltic
pump for removing condensate. The upper GL connection is for the core of the heated line. Avoid contact with the anti-freeze
heating.
The glass pearls can be cleaned and replaced, if necessary.
