5. In vertical installations, ensure the sys-
tem cable drops vertically from the
Oxymitter 4000 and the conduit is
routed below the level of the electron-
ics housing. This drip loop minimizes
the possibility that moisture will dam-
age the electronics (Figure 2-9).
6. If the system has an abrasive shield,
check the dust seal gaskets. The joints
in the two gaskets must be staggered
180°. Also, make sure the gaskets are
in the hub grooves as the Oxymitter
4000 slides into the 15° forcing cone in
the abrasive shield.

7. Insert probe through the opening in the
mounting flange and bolt the unit to the
flange. When probe lengths selected
are 9 to 18 ft (2.74 to 5.49 m), special
brackets are supplied to provide addi-
tional support for the probe inside the
flue or stack (Figure 2-7).
If process temperatures will exceed
392°F (200°C), use anti-seize com-
pound on stud threads to ease future
removal of Oxymitter 4000. For probe
temperatures that will exceed 185°F
(85°C), we recommend the remote
mounted electronics option.
