61-1020/61-0230 Molecular Property Spectrometer
Installation
This section describes procedures to mount the combustible gas detector in the monitoring
environment and wire it to a controller.
If you purchased a 61-0230 detector that is factory installed and wired to a controller, detector
installation is not necessary, but the detector wiring can be confirmed as described in “Wiring the
Combustible Gas Detector to a Controller” on page 9.
Mounting the Combustible Gas Detector
1. Select a mounting site that is representative of the monitoring environment. Consider the
following when selecting 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 selected mounting site, hang or mount the junction box with the detector facing down
(see Figure 2).
