strut out of the probe tube (Figure 4-8).
f. When replacing the strut, 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 calibra-
tion gas line. When the hole and the cali-
bration gas line are aligned correctly, the
