Carefully inspect the shipping container for any evidence of damage. If the
container is damaged, notify the carrier immediately.
Confirm that all items shown on the packing list are present. Notify
Rosemount immediately if items are missing.
Before installing this equipment, read the "Safety instructions for the wiring and installation
of this apparatus" in Appendix A. Failure to follow safety instructions could result in serious
injury or death.
Avoid installation locations near steam soot blowers.
1. The location of the oxygen probe in the stack or flue is important for
maximum accuracy in the oxygen analyzing process. The probe must
be positioned so the gas it measures is representative of the process.
Longer ducts may require several analyzers since the O
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 sensing point should be selected so the
process gas temperature falls within a range of 550° to 1400°C (1022°
to 2552°F). Figure 2-1 provides mechanical installation references.
2. Check the flue or stack for holes and air leakage. The presence of this
condition will substantially affect the accuracy 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 access to the probe. Allow
adequate clearance for probe removal (Figure 2-1).
