Overview
This manual describes the 61-1000RK combustible gas detector (internal amplifier type).
This manual also describes how to install, start up, maintain, and calibrate the detector
when it is 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 61-1000RK combustible gas detector includes the 61-0140RK combustible gas detector
and a junction box. This manual may also be used for the 61-0140RK 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 61-0140RK combustible gas detector,
disregard all references to the junction box and junction box terminal strip.
