Installation
This section describes procedures to mount the combustible gas transmitter in the
monitoring environment and wire the transmitter to a controller.
Mounting the Combustible Gas Transmitter
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 transmitter 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.

If the detector is mounted to the junction box, skip to step 5. If not, continue with step 2.
2. Remove the junction box cover.
3. Guide the four wires that extend from the top of the detector through the bottom
conduit hub of the junction box.
4. Screw the detector into the bottom conduit hub of the junction box.
5. At the monitoring site, use #10 screws through the junction box’s two mounting holes
to secure the junction box to a vertical surface.
