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.
NOTE
If process temperatures will exceed 392°F
(200°C), use anti-seize compound on stud
threads to ease future removal of Oxymitter
4000.
7. Insert probe through the opening in the
mounting flange and bolt the unit to the
flange. When probe lengths selected are 9 or
12 ft (2.74 or 3.66 m), special brackets are
supplied to provide additional support for the
probe inside the flue or stack (Figure 2-6).
Uninsulated stacks or ducts may cause
ambient temperatures around the
electronics to exceed 149°F (65°C),
which may cause overheating damage to
the electronics.
8. If insulation is being removed to access the
duct work for Oxymitter 4000 mounting,
make sure the insulation is replaced afterward
(Figure 2-8).
