During normal measurement, all the gas flows through the device and is then
discharged as waste gas via other pipelines into safe venting areas outside buildings
due to the permanent flow of flammable gas. It must be discharged without any
backpressure. Therefore, the diameter of the pipeline must never be reduced.
A 6 mm pipeline is generally sufficient. If a great deal of gas passes through the bypass
or a high volume of flushing gas is to be used, a separate waste gas line should ideally
be installed for this gas to prevent return effects. The waste gas lines must be protected
from dirt and moisture.
If gas inlets or outlets are not used, they must be sealed using blind plugs.
ATTENTION
The pipeline at the breather valve (if connected) is not part of the waste
gas system and must never be connected to other waste gas lines

Connect the waste gas to the relevant outlets. Always discharge the gas from (MV) separate.
1.
Avoid back pressure formation and mutual interference in the exhaust system.
Connect the pipelines immediately after you have removed the sealing elements (blind plugs or
2.
screw plugs) from the gas outlets on the device.
Since it is not possible to conduct a tightness test when the device is switched off, the waste gas
3.
line must be checked for leaks with a gas detector during the flushing cycle. This test must be
carried out first of all once the device has been installed and is operating.

Ensure that the required work described in the previous sections has been completed. In particular,
1.
the pipelines must have been flushed.
Ensure that the process gas pipeline is connected to the sample sensor and that the shut-off valve
2.
in the process gas pipeline is closed. (If there is a pressure regulator, turn the regulator to its lowest
setting.)
3.
Ensure that a process gas inlet pressure range according to chapter 2.4 can be set.
Remove the protection (sealing plugs or screw plugs) from the relevant inlets, ensuring that the
4.
connection on the housing is not released since otherwise the pipes soldered to it will be damaged.
Therefore use a second wrench to limit the rotary movement on the connection coupling.
Connect the pipeline properly.
5. NEVER OPEN THE GAS SUPPLY IF THE COUPLING HAS BEEN DETACHED.
In this case; you should always contact your TAC.
Carefully open all the shut-off controls, valves and regulators in the process gas route to slowly
6.
increase the pressure up to operating conditions.
