4. If using the optional ceramic diffusor
element, the vee deflector must be cor-
rectly oriented. Before inserting the
probe, check the direction of gas flow
in the duct. Orient the vee deflector on
the probe so that the apex points up-
stream toward the flow (Figure 2-2).
This may be done by loosening the
setscrews, and rotating the vee de-
flector to the desired position.
Retighten the setscrews.
5. In horizontal installations, the probe
junction box should be oriented so the
system cable drops vertically from the
probe junction box. In a vertical instal-
lation, the system cable can be ori-
ented in any direction.
6. If the system has an abrasive shield,
check the diffusion element dust seal
packings. The joints in the two pack-
ings must be staggered 180°. Also,
make sure that the packings are in the
hub grooves as the probe slides into
the 15° forcing cone in the abrasive
shield.
7. Insert the probe through the opening in
the mounting flange and bolt the unit to
the flange. When probe lengths se-
lected are 9 or 12 feet (2.74 or 3.66 m),
special brackets are supplied to pro-
vide additional support for the probe
inside the flue or stack. See Figure 2-1,
sheet 5.
