61-1003RK/61-0190RK Combustible Gas Detector • 1
Overview
This manual describes the 61-1003RK combustible gas detector. This manual also
describes how to install, start up, maintain, and calibrate the detector when used with a
gas monitoring controller. A parts list at the end of this manual lists replacement parts and
accessories for the combustible gas detector.
The 61-1003RK combustible gas detector includes a junction box. This manual may also be
used for the 61-0190RK combustible gas detector which does not include a junction box
and is normally mounted in one of a controller’s conduit hubs. If you are using a 61-
0190RK combustible gas detector, disregard all references to the junction box and junction
box terminal block.
