Assembly

8. See Figure 9-8. Grasp the wire loop and carefully slide the heater strut

assembly (32, Figure 9-3) out of the probe tube.

9. When replacing the strut, orient the probe so that the small calibration

gas tube lays at the 6 o'clock position of the probe tube. Align the slot on

the heater plate with the calibration gas line in the probe tube. Slide the

strut into the probe tube. It will turn to align the hole on the back plate of

the strut with the calibration gas line. When the hole and the calibration

gas line are aligned correctly, the strut will slide in the rest of the way.

10. As the strut installation nears completion, install the guide rod into the

calibration gas tube to assist in guiding the calibration gas tube through

the hole in the end of the strut.

11. Push down on the back plate of the strut to make sure you have spring

tension and then install the strut pressure clamp (34) on the back plate.

12. Install gas port fittings (29) in the CAL, REF, and VENT ports.

13. Replace the CAL and REF gas silicon tubes (34) and tube clamps (33).

14. Install the entire electronics per "Replacement of Entire Electronics (with

Housing)", steps 4 and 5.

15. Follow the instructions in "Probe Installation" in Section 2: Installation to

install the Hazardous Area Oxymitter 4000 into the stack or duct.
