Installation
This section describes procedures to mount the combustible gas detector in the
monitoring environment and wire it to a controller.
Mounting the Combustible Gas Detector
1. Select a mounting site that is representative of the monitoring environment. Consider
the following when you select the mounting site.
• Select a site where the detector is not likely to be bumped or disturbed. Make sure
there is sufficient room to perform start-up, maintenance, and calibration
procedures.
• Select a site where the target gas is likely to be found first. For lighter gases,
mount the detector near the ceiling; for heavier gases, mount the detector near the
floor.

2. At the mounting site you select, hang or mount the junction box with the detector
facing down (see Figure 1).
