oxygen and combustibles can vary due to stratification. A point too near the wall
of the duct or the inside radius of a bend may not provide a representative
sample because of the very low flow conditions. Select the sensing point so the
process gas temperature falls within the range of probe material used.
CAUTION
Damage to the electronics may result.
Do not allow the temperature of the electronics housing to exceed 185 °F (85 °C).
CAUTION
Failure to connect the pneumatic lines can allow the flow of contaminants into the
transmitter's ports.
Whenever a positive stack pressure exists at the installation site, be sure to
connect all pneumatic lines prior to installing the transmitter in the stack or
ductwork.
Procedure
1. Check the flue or stack for holes and air leakage.
The presence of this condition will substantially affect the accuracy of the
oxygen and combustibles readings. Make the necessary repairs or install
the transmitter upstream of any leakage.
2. Ensure the area is clear of internal and external obstructions that will
interfere with installation and maintenance access to the transmitter.
Allow adequate clearance for the removal of the transmitter.
