6.2 Connecting the gas tubes
6.2.1 Connecting the sample gas tubes
The sample tubes must be connected carefully with appropriate fittings. This holds as well for the optional
calibration ports.
The connection fitting (diameter 6) for the sample tube on heated probes should be as short as possible
and the insulation of the sample tube should fit into the probe insulation as close as possible. For carrying
out this step remove the insulation by loosing the fixing bolts.
CAUTION
Breakage hazard
The insulation is brittle.
Handle with care, don’t drop it.
When the sample tube is installed, fix it with the bracket (GAS 222.20-HT).
Longer sample tubes may require more fixing brackets on their way down to the system.
After all tubes have been fixed and checked for leakage, put the insulation back in place and secure it
carefully.
WARNING
Emission of gas
Measuring gas may be harmful
Check the tightness of all tubes.
6.2.2 Connecting the calibration gas tube (option)
A tube fitting ø6 mm is needed for connecting the calibration gas tube.
If the calibration gas connector had been ordered with check valve, the 6 mm tube can be connected
directly to the check valve.
