4 Installation
Installation shall be in accordance with the standards in force, classification of
the zone, and in conformity with standard EN/IEC 60079-14, the editions in
force, or with other national and/or local standards.
4.1 Positioning
Both GD10P and GD10PE detectors should be mounted where gas leakage is most likely to
occur. To detect methane, which is lighter than air, inside an enclosed area the detector should
be mounted high in the area to be protected or immediately above potential leakage sites.
To detect gases heavier than air, e.g. propane, the detector should be mounted below the
potential leakage site.
The detector should be mounted in a place where maintenance, i.e. cleaning of the optics, is
easily performed.
The detector may be mounted in areas where no oxygen is present.
The detector may be mounted in areas with strong airflow
The detector can be mounted where it could be drenched by water.
However, immersion has its limits. It assumes that the cable glands have been correctly mounted.
Furthermore, the detector will trigger an optical fault. After immersion, the detector will require
cleaning because of the possible traces caused by immersion on the optical parts.
Finally, it is also important to check that the gas inlet tube is properly covered so that there is
nothing getting inside.
Please note that the 4 holes in each end of the GD10PE weather protection are for water
drainage, and should not be blocked.
Air velocity limits: none

Taking into account the principle of detection, a pressure variation will proportionally influence the measurement compared to
the calibration one (1013HPa).
