INSTALLATION

2-1 PRE-INSTALLATION

a.Inspect

Carefully inspect the shipping container for any evidence of damage. If the container is damaged, notify the carrier immediately.

b.Packing List

Confirm that all items shown on the packing list are present. Notify Rosemount Analytical immediately if items are missing.

Before installing this equipment, read the “Safety instructions for the wiring and installation of this apparatus” at the front of this Instruction Bulletin. Failure to follow the safety instruc- tions could result in serious injury or death.

2-2 MECHANICAL INSTALLATION

Avoid installation locations near steam soot blowers.

a.Locating Oxygen Probe

1.The location of the oxygen probe in the stack or flue is important for maxi- mum accuracy in the oxygen analyzing process. The probe must be positioned so the gas it measures is representa- tive of the process. Best results are normally obtained if the probe is posi- tioned near the center of the duct (40- 60% insertion). Longer ducts may re- quire several analyzers since the O2 can vary due to stratification. A point too near the wall of the duct, or the in- side radius of a bend, may not provide a representative sample because of the very low flow conditions. The

2

sensing point should be selected so the process gas temperature falls within a range of 550° to 1600°C (1022° to 2912°F). Figure 2-1provides mechanical installation references.

2.Check the flue or stack for holes and air leakage. The presence of this con- dition will substantially affect the accu- racy of the oxygen reading. Therefore, either make the necessary repairs or install the probe upstream of any leakage.

3.Ensure the area is clear of internal and external obstructions that will interfere with installation and maintenance ac- cess to the probe. Allow adequate clearance for probe removal (Figure 2-1).

b.Installing Oxygen Probe

The probe was specially packaged to prevent breakage due to handling. Do not remove the padding material from the probe until immediately before installation.

1.Ensure all components are available to install the probe.

NOTE

Leave the probe inner protective cover in place until installation. This is re- quired to protect the ceramic cell dur- ing movement.

2.If using an optional adapter plate (Figure 2-2)or an optional mounting flange (Figure 2-3),weld or bolt the component onto the duct. The through hole in the stack or duct wall and re- fractory material must be 2 in. (50.8 mm) diameter, minimum.
