4 • 65-2400RK Combustible Gas Transmitter
Junction Box
Use the junction box to install the combustible gas transmitter at a mounting site that is
remote from the controller. The junction box also protects the amplifier and wiring
connections made to the amplifier. Use the two 3/4 in. conduit hubs to mount the detector
to the junction box (bottom hub) and connect wiring from the amplifier to the controller
(top hub). The detector has 1/2 in. NPT mounting threads, so a 3/4 in NPT. x 1/2 in. NPT
reducer is used to mount it.
NOTE: The combustible gas detector and amplifier are factory-mounted to the
junction box.
Use the junction box’s two mounting holes to mount the combustible gas transmitter to a
vertical surface at the monitoring site. Use the cover on the front of the junction box to
access the interior of the junction box.
