After selecting the probe mounting location, provision should be made for a platform where the probe can be easily serviced. The intelligent field transmitter (IFT) can be located up to 150 ft (45 m) cabling distance from the probe when used without optional heater power supply (HPS). When the sys- tem includes the optional HPS, the HPS can be located up to 150 ft (45 m) cabling dis- tance from the probe and the IFT may be located up to 1200 ft (364 m) cabling dis- tance from the HPS.

A source of instrument air is required at the probe for reference air use. Since the probe is equipped with an in-place calibration feature, provision should be made for con-

necting calibration gas tanks to the oxygen analyzer when the probe is to be calibrated.

If the calibration gas bottles will be perma- nently hooked up, a check valve is required next to the calibration fittings on the probe junction box. This is to prevent breathing of calibration gas line and subsequent flue gas condensation and corrosion. The check valve is in addition to the stop valve in the calibration gas kit or the solenoid valve in the multiprobe calibration gas sequencer units.

An optional Z-purge arrangement is avail- able for applications where hazardous area classification may be required (See Appli- cation Data Bulletin AD 106-300B).
