Introduction
The Bacharach Flue-Gas Sample Conditioning System consists of the
following components:
• Probe with Peltier Cooler
• Condensate Pump with Water Trap
• Power Supply
The function of this system is to remove water vapor from the fl ue-gas
sample, thus preventing the formation of water droplets inside the
probe hose. If water droplets were to form inside the hose, a por tion of
the gas sample could be ab sorbed by the water, thus resulting in lowerthan-actual read ings of NO

Water vapor is removed from the fl ue-gas sample by passing the sam ple
through a Peltier Cooler where the sample is chilled, which in turn,
causes the water vapor contained in the gas sam ple to be removed from
the sample.
The water that was extracted from the gas sample is then pumped out
of the Peltier Cooler and into a water trap.
The now dry, conditioned fl ue-gas sample is then sent to its as so ci at ed
com bus tion test equipment for analysis.

Equipment Setup
Refer to Figure 2. If not already done, attach the Peltier cooler to the
probe as sem bly by fi rst removing the plastic end cap from the rear of
the probe, and then inserting the cooler’s inlet connector, en sur ing fi rst
that a fi lter is present between the cooler and probe.
Attach the pump’s inlet hose to the bottom of the Peltier cooler. Water
that is condensed from the fl ue-gas sample will be pumped into the con-
densate pump’s reservoir through this hose. Note that the con den sate
pump can be placed in an upright, horizontal, or hanging po si tion. A
mag net mounted in the base of the pump allows the pump to be attached to overhead ductwork.
Connect the power supply’s DC output connector to the con den sate
pump; then connect the condensate pump’s DC output power con nec tor
to the Peltier cooler. The Peltier cooler and its associated con den sate
pump are started by plugging the power supply into a source of AC
power that is be tween 100 and 240 VAC, 50/60 Hz.
Connect the probe assembly’s stack-temperature thermocouple con nec tor, pres sure fi tting, and fl ue-gas fi tting to the combustion an a lyz er
per the analyzer’s instruction manual.

Operation
When ready to conduct a combustion effi ciency test, plug in the power
supply of the Flue-Gas Sample Conditioning System. You should hear
the condensate pump start run ning and see the Peltier cooler’s red LED
turn on and off as the cooler is cy cled. Note that the cool er’s operating
time changes ac cord ing to its tem per a ture.
Set up and confi gure the combustion analyzer as described in its in-
struc tion manual. Then insert the probe into the fl ue stack and begin
testing.
During the combustion test, the condensed water vapor from the fl ue
gas will ac cu mu late inside the pump’s reservoir. If the water level begins to approach the ends of the tubes inside the reservoir, then stop the
test and empty the reservoir as described in the Main te nance Section of
this manual.
WARNING! The probe tube is hot! In the following step, be
sure to allow the probe tube suffi cient time to cool before
handling.
At the conclusion of the combustion test, remove the probe from the
stack; then unplug the Peltier cool er’s power supply.

Maintenance
Probe
The probe’s sponge-type fi lter (Figure 3, Item 9) needs to be in spect ed at
reg u lar intervals for dirt contamination. Replace fi lter as nec es sary by
fi rst pulling out the Peltier cooler from the probe and then ex chang ing
the fi lter with a new one.
Peltier Cooler
The cooler’s wadding fi lter (Figure 3, Item 12) needs to be in spect ed at
regular in ter vals for dirt contamination. Re place fi lter as nec es sary by
fi rst pulling off the fi lter chamber’s top cap and then ex chang ing the
fi lter with a new one.
Condensate Pump
Flue Gas Sample Conditioning System
WARNING! The condensed water will be warm and slightly
acid ic. Take all necessary precautions to pre vent the water
from splashing into your eyes or con tact ing your skin.
Empty the pump’s reservoir (Figure 3, Item 15) by fi rst holding the
pump with its reservoir facing downwards. Then twist the reservoir 90
de grees (either clock wise or counterclockwise) to free it from the pump
base. Empty the res er voir; then reattach it to the pump. Before re at tach ing the reservoir, however, make sure that the res er voir’s o-ring
(Figure 3, Item 20) is prop er ly po si tioned inside its grove in the pump
base.
The pump’s wadding fi lter (Figure 3, Item 17) needs to be in spect ed at
regular in ter vals for dirt contamination. Replace fi lter as nec es sary by
fi rst unscrewing the fi lter chamber cap and then ex chang ing the fi lter
with a new one.
