4. Combustion Measurement
4.1 Prepare Combustion Measurement
Prepare instrument for measurement operation by making all connections (T-Room sensor and T-Gas, GAS and DRAUGHT of the 3chamber hose). Make sure that:
-the water trap contains no humidity
-the fine dust filter and the safety filter are not soiled darker
than no. 3 on the soot scale
4.2. Gas Analysis
Just position the probe in the exhaust pipe once the
calibration phase is over!
To obtain accurate measurement values it’s
important to re-calibrate the instrument after each
measurement (at the latest after one hour)!
Once the calibration cycle is over, the instrument enters the measurement mode. The measurement values could be displayed on 4
screen pages (3 x gas analysis; 1 x draught measurement – change
with curser keys):

The position of the measured and calculated values (gas analysis)
can be selected freely on the display. To change the position or the
composition, please proceed as follows:
-with <Enter> / <Display values> / <Enter> activate the first line on
the display
-choose with curser key the measured or calculated value
-with <Enter> activate the next line on the display and so on
-with <ESC> or <Enter> in the last line you leave this process.
The values for CO2, Efficiency, Losses, Lambda and the Dew Point
are calculated values. They just can be calculated when realistic
figures for the basic values like O2 and the temperature are available.
It must be assured that:
O2 < 20,7 %
The dew point can just be calculated correctly if in the menu “Adjustments / Air pressure” the current barometric air pressure has
been entered. If the combustion gas temperature falls below the dew
point /between 25 and 65°C) the efficiency will be calculated with
condensation gain. In this case a (C) is displayed behind the efficiency . Correct measurement values are displayed after a delay of 1
to 1,5 minutes necessary for the gas transport to the sensors and to
establish a stable electrochemical reaction in the sensors. For storage and printing wait for the values to become stable. If the gas value still fluctuates for more than 2 ppm, the reason could be in an
unstable draft condition in the gas channel.
Once the measurement values are stable
and the results can be printed, press <record> to transfer the values to the temporary memory. Data will be stored here for
later printout (the values of the temporary
memory could be checked by pressing
<Enter> / <Memory> / <Enter>. While
checking the values the gas pump will be
switched off in order to spare the sensors.

CO-switch-off with purging pump (option)
The internal program protects the CO-sensor for overload. In case
the limit of 4000 ppm (CO sensor with H2) is exceeded a second
pump switches on and purges the sensor with fresh air. After sufficient purging time (blinking: "CO"), the sensor can be brought back
to the measurement mode with <Enter> / <CO MV ON/OFF> / <Enter> (the sensor can also manually be switched off by pressing <Enter> / <CO MV ON/OFF> / <Enter>).
4.3. Draft Measurement
The gas measurement mode already provides a trend indication of
the draught conditions in the combustion gas channel. As the pressure sensor is very sensitive and tend to drift, the value will not be
recorded by pressing <record>. It is therefore recommended to recalibrate this sensor prior to the actual measurement and results
printing.
The current value will be displayed as well
as the remark to reset the zero point of the
sensor. Therefore disconnect the draught
hose from the instrument and press the key
<CAL>. By this the sensor is calibrated.
Connect the draught hose again with the
instrument. The exact measurement value
is displayed now and can be stored by
pressing <record> and added to the other
values already in the temporary memory.
The stored value will appear on the display.

After determination of the burning capacity
the next point of the routine is the COmeasurement. By pressing the curser
<down> a 1-minute calibration cycle starts
for flashing the sensors with fresh air. During calibration cycle the probe must not be
positioned in the combustion tube. After
calibration cycle the CO-content of the
surrounding air can be determined. Use the
probe to check the area around the boiler.
Beside the stored value (press key <record>) the instrument stores maximum COvalue of the measurement.
Next point of the routine (curser key
<down>) the CO-value in the combustion
tube of the boiler is determined. For measurement the probe must be positioned in
the combustion tube. Apart from the stored
value the maximum CO-value of the measurement is stored.
After storing the CO-values the next point
are the draught measurements (curser key
<down>). For exact measuring it’s recommended to reset the sensor to zero. Remove the draught hose off the instrument
and press <CAL>. The zero point of the
sensor is set now. After the draught has
stabilised it can be stored for later printout
by pressing the key <record>.
At the end of the measurement routine
(curser down) it is checked whether a gas
leakage at the unit could be determined.
Confirmation could be done by using the

9. Control
The electrochemical sensors used for gas analysis are submitted to
a wearing process and age. Along the operation period, they alter
their output values depending on the gas concentration, flow duration
and soiling degree of the measured gases. The programme controls
the sensors and corrects drifts. If drifts and the correlated measurements errors increase, an error message is displayed. In this case
the corresponding sensors must be changed by one of our authorised service centres. The actual status of the sensors is displayed in
the control menu. Additionally on two more pages will be displayed
(change the display pages by using the cursers):

11. Maintenance Tips
To secure the accuracy of your measuring instrument we recommend the annual check by an authorized ecom partner. In the case
of strong demand (e.g. permanent several hours of measurement
per day, rough conditions etc.) shorter intervals between checks
should be selected - please contact your ecom partner. All ecom
partners are listed under www.ecom.de. Do not use other sensor
than supposed by our factory and be aware that service done by
service stations not authorised by ecom will lead to expiration of any
warranty.
The following tips for the daily care of accessible parts and components should be helpful:
Dust filter on top of the water trap
Unscrew the top cap of the water trap and check the condition of the
particle filter. When the filter becomes grey it should be changed
(soot number approx. 2-3).
Fine dust filter
Sensors
Each time the instrument is switched on the sensors are calibrated
with fresh air. The instrument permanently monitors the condition of
the sensors. New sensors wear out from use in time due to reaction
(O2-sensor) and due to soiled gases respectively gases in concentrations beyond the nominal range (toxic sensors). The output values
of the sensors are (see menu “Control”):
O2
CO
NO
ecom-CL2
1100 - 1400 mV
0 mV (+/- 30)
0 mV (+/- 30)
Seite 39
If an error message is displayed during calibration cycle and does
not disappear after repeated calibrations the instrument must be
send to a service centre. The O2 sensor should show > 300 mV,
otherwise it should be changed.
The CO-sensor is protected by the internal program for overload. In
case the limit of 4000 ppm is exceeded the gas pump is switched off.
Power supply
The battery ensures a main power independent operation. The battery is automatically charged when the instrument is connected to
the main power supply. (Please do not interrupt the charging shortly
since the charging circuitry could operate faulty.) The recharge of the
battery should be done in any case if the voltage display (menu
“Control”) is less than 5.8 V (Instrument will stop working at 5.5 V).
Sampling probe and hose
Depending on the frequency of use the probe and the hose must be
cleaned regularly, thus in order to prevent particles from lodging and
early ware due to corrosion.
The hose can be cleaned after all connections on the instrument and
the probe itself have been switched off (use warm water and then
blow out to dry)
Replace paper roll
Unlock the printer by pulling on the tab on the printer cover. Remove
the plastic holder of the spent paper roll and insert the new paper roll
as shown. Leave some paper stand out and close the printer cover.

13. FAQ
Where do I find important instrument information?
In the menu „Control“ all important instrument informations are shown (e.g. battery voltage, sensor
values, unit number, next service date, operation
hours etc.). With the arrow keys stands you can
switch to the second page.
How long is the life span of the
sensors?
The life span depends on the operating hours and
the instrument equipment. The life span of the toxic
sensors (CO, NO, SO2, NO2) is affected by high gas
concentrations and a not sufficient purging. The life
span for these sensors amounts to on the average
between 4 and 6 years. The life span of the O2 sensor is independent of the operating hours and
amounts to approx. 4 years.
Which sensors can I exchange?
Please contact the next authorised service centre for
changing sensors.
The instrument shows the error
message „O2 sensor 0 mV“!
The sensor must be renewed.
The instrument shows the message „Check required“!
This message appears automatically every 12
months or after 250 operating hours. Note: This is a
recommendation to let check the instrument. The
instrument is however still ready for use.
The instrument shows the error
message „T-Gas“ or „T-Air“!
Possible reasons could be:
- Cable is broken (at the plug)
- T-Air sensor is broken
- Thermocouple is broken
- Cable is defective
Note: The error messages can be ignored at the CL2
by pressing „Enter“. Calculations that depend on
these temperatures are not implemented.
The instrument shows wrong or
inaccurately CO2 values!
Possible reasons could be:
- O2 is defective (CO2 values are calculated from
the O2 values)
- Pump is not working correctly
- Leakage in the gas way
- condensate trap / gas cooler is clogged
Seite 42
ecom-CL2
My instrument cannot be
switched on!
- Please check the mains cable
- Please check the fuse
- Please check mains connection (Plug socket
switched on?)
- Please load the accumulator min. 8 hours
(Accumulator could be over-discharged)
My instrument does not print!
Please check whether the printer paper is correctly
inserted. The thermal printer writes only on the thermally sensitive side. Please use always the correct
paper for the printer, you will prevent defects at the
printer. Please make sure that the printer is clean (no
chads in the drive).
Can I change the printout?
You can change the printout (Menu: “Adjustments”).
Hint: If you have several instruments of the same type, you can locate an error by
exchanging the accessories (probe, hose, temperature sensor etc.).
If further questions or problems should arise, please contact the next authorised service centre.
