  Instruction Manual IM-106-880, Rev 1.0 OCX 8800 January 2007 The catalyst is specifically designed to detect carbon monoxide (CO), but the sensor responds to other combustible gases. The sensor is calibrated using CO, thus the output should be expressed in terms of CO. However, since the sensor detects other combustible gases, the output cannot just be labeled CO.

  Instruction Manual IM-106-880, Rev 1.0 OCX 8800 January 2007 MECHANICAL Selecting Location INSTALLATION 1. The location of the OCX 8800 in the stack or flue is most important for maximum accuracy in the oxygen analyzing process. The probe must be positioned so the gas it measures is representative of the process. Best results are normally obtained if the transmitter is positioned near the center of the duct (40-60% insertion).
