1.2 OPERATING INSTRUCTIONS
Everyone working with the BluFlame must carefully read and
understand these operating instructions before starting their
work. Always keep these operating instructions at the
BluFlame’s location of use.
These operating instructions are an important part of the package
and are not only intended to illustrate how to operate and use the
BluFlame, but also, and above all, to ensure the safety of its users and to
protect the environment. Accordingly, every user must familiarize themselves
with the contents of these operating instructions and follow all instructions
without fail.
When handing over the BluFlame to other parties, make sure to include the
operating instructions.
1.3 WARRANTY CLAIMS
Immediately check the initial shipment for damage in the presence of
the person delivering it. All damage must be confirmed by the person
delivering the shipment and reported within 3 days. Failure to do so will result
in your claim being denied.
This is a high-quality electronic measuring device. In order to
ensure that it will work for an extended period of time, the device
features low self-discharge rechargeable batteries. Accordingly, it is
recommended to charge the BluFlame after 2 to 3 months – even if it is not
used during this period, turn it on, and wait for the calibration phase to be
completed.
Keep the original box and the packaging material in case you need to send
in the BluFlame.
1.4 IMPORTANT INFORMATION
• The BluFlame is only suitable for short-term measurements.
• The BluFlame must be visually inspected before being turned on. This
visual inspection must also include checking for damage/soiling on the
probe, on the tube ports on the BluFlame, and on the condensate trap with
a star filter.
• When the BluFlame is turned on, it will automatically run a calibration
routine for its sensors (zeroing – please refer to section 6.8, “Turning on
and zeroing,” on page 13). Once this routine starts, and depending on the
sensors’ state, it will take about 1 to 3 minutes for the BluFlame to be ready
for operation.
• After zeroing, the required minimum time for a full correct measuring cycle
will be 1.5 minutes.
• Aggressive acidic atmospheres (sulfur) and vapors from alcohol
compounds (e.g., thinner, gasoline, ethanol, varnish) can ruin the sensors
in the BluFlame.
• The expected service life for the sensors is approx. 2 years for the O2
sensor, approx. 2–3 years for the CO sensor, and approx. 3 years for the
NO sensor, with the actual service life depending on how the BluFlame is
used, maintained, and cared for.
• The service life of the rechargeable battery is at least 500 charge/discharge
cycles. The higher the number of cycles, the shorter the time that the
device will be able to run after the battery is recharged.

• If the pocket star filter (2) is heavily soiled or not working, replace it.
• Both sealing plugs have a gasket. Make sure that these gaskets are
correctly inserted and undamaged. If they are damaged, replace them.
• Reassemble the condensate trap.
6.7 CHECKING THE CONNECTIONS AND CHECKING
FOR LEAKS
• Check all connections to make sure they are fitted properly.
• Check all tubes, tube connections, and the condensate container (from the
probe tip all the way to the gas port on the BluFlame) for leaks.
The BluFlame features an integrated automatic test for checking
the gas circuits for leaks. The corresponding procedure is described
in section 9.4, “Leak test,” on page 17.
6.8 TURNING ON AND ZEROING
• Tap the display and then the Power icon.
 ➡The BluFlame will run a zeroing routine automatically.
Make sure that the probe is not in the flue gas stream
during zeroing.
During zeroing, a blue bar will be shown at the
top of the display in order to indicate the zeroing
routine’s progress.
Once the zeroing routine is complete, the
BluFlame will be ready for measurements.
If any of the sensors are faulty, this will be
detected during zeroing and indicated with an
error message.
Running the zeroing routine again
• You can run the zeroing routine again during operation. To do so, go to the
“Measurement” main menu and select the “Zero setting...” option.
Carrying out Measurements
Every BluFlame features the full functionality required to carry out
flue gas measurements. Following is a description of the process for this
flue gas measurement.
After it is turned on, the BluFlame will have the Measurement menu active.
7.1 SELECTING A MEASURING PROGRAM
• Under “Gas measurement,” select one of the four defined measuring programs.
or
• In the “Gas measurement” main menu, tap the “Start button” to directly
start the most recently selected measuring program.
7.2 READING SCREENS
The readings will be organized into five screens with 4 readings each, and
can be configured as described in section 5.4, “Configuring measuring
programs,” on page 10.
Both direct measurands such as oxygen content and temperature and
calculated values such as dew point, CO2 content, etc. are available as
readings. In addition, it is possible to have the same reading be converted to
various different units, e.g., CO in ppm or mg/kWh.
Unavailable readings will be shown as hyphens. Reasons why a reading is
not available can include the following:
• An electrochemical sensor was diagnosed as being faulty during zeroing.
• External temperature sensors are not connected.
7.3 CO LIMIT
If the CO limit is exceeded, the CO readings’ color will change (red).
This CO limit can be adjusted – please refer to section 5.5, “Setting the CO
limit,” on page 10.
7.4 SPECIFIC MEASURING APPLICATIONS
Test Bed Program
The test bed program is used with test beds in order to test the BluFlame
with test gas in the measuring program.
No calculations are performed during this test, and no alarm will be emitted
if the CO limit is exceeded.
The test bed program has no relevance to you as a user, as it is not intended
for end user applications.
7.5 PRINTING OUT MEASUREMENT RESULTS
• In each measuring program, you can use the print-out button on the
reading screen / to print out the readings shown on reading
screens 1 through 5. Duplicate values will be skipped.

14
7.6 STOPPING A MEASUREMENT
You can stop an ongoing flue gas measurement at any time by using the
stop button. When you do this, the screen will change color and the readings
will be frozen.
All the readings available at the time the measurement stops will continue
to be available in the BluFlame, and it will still be possible to display them.
To go back to the Measurement main menu, tap the Back button.
7.7 LAST MEASUREMENT VALUES
The BluFlame has the option of continuing to work with the most recent
readings after a measurement ends.
• To do this, select “Last measurement values” in the main menu. Once
there, you will be able to display, print out, or save the readings.
7.8 PRESSURE MEASUREMENTS
Four pressure readings can be recorded in the
“Pressure measurem.” menu.
While the current reading is being displayed,
you can copy it to the selected storage space.
These settings are available in the context menu.
You will need to connect the tube (e.g., for a
draft measurement) to port P2.
For a differential pressure measurement, you
will need to connect the second tube to port P1 – please refer to section 4.7,
“Connection configuration for draft measurements,” on page 9.
“Pressure too high” draft sensor error message
Excessively high pressure may ruin the draft sensor.
• Make sure to stay within the pressure sensor’s measuring range.
7.9 DIFFERENTIAL TEMPERATURE MEASUREMENT
Two temperatures can be measured in the
“Temp. measurement” menu. When
temperature sensors are connected to ports T1
and T2, the temperature differential will be
measured and displayed.
Make sure to only use AccuTools temperature sensors in order to
ensure that you will get an accurate differential temperature
measurement.
7.10 CO (AMBIENT)
The goal of this measuring program is to verify a CO concentration in the
measuring location’s surroundings. When you change the country, the
CO (ambient) menu option will appear.
• Run a zeroing routine on fresh air (outside of the measuring
location’s surroundings).
• Run the “CO (ambient)” function on fresh air.
The current CO value from the zeroing will be shown for reference purposes –
this value must be close to 0 ppm.
The current CO (ambient) value and the peak value will be shown.
7.11 AFTER MEASUREMENT
Once the measurement is complete, remove the flue probe from the flue pipe
and seal the inspection hole properly (with sealing compound or adhesive tape).
Risk of burns and fire posed by hot flue probe
This may result in physical injuries and material damage.
• Let the hot probe tube cool down.
Risk of thermocouple damage
• Once the probe has cooled down, slide the probe cone over
the probe tip and secure the probe cone.
Storage
8.1 HOW DATA IS STORED
The basic way in which data is stored in the BluFlame is in the form of a
stored set of sites. You can save data records in each of these sites. Each site
will have a unique site number. You can use up to eight text lines per site
and name these lines, e.g., customer names, addresses, etc.
New sites created in the BluFlame cannot be transferred to a PC.
When transferring data from the BluFlame to the PC, only readings will be
transferred (identified by the site number). Measurements are stored when
they are assigned to a site.

15
8.2 STORAGE INFORMATION
• In the “Storage” menu option, select the “Storage info” option to view
information about the saved site and the measurements.
• Up to 1,000 sites and 3,000 readings can be stored.
8.3 SITES ADMINISTRATION
In the “Sites administration” menu option, you can:
• View all the data for the saved sites
• Create new sites
• Delete sites
Changes made to the data for a site will not be transferred to the PC.
New sites created in the BluFlame will not be transferred back
to the PC.
Viewing sites
When you select the “Site administration” option, a page with the following
will be shown for each saved appliance:
• The unique site number in the first line, shown in color
• The eight additional free-form text lines
Use the arrow buttons to scroll through all the sites.
Creating new sites
In the “Sites administration” menu option, you can create new sites and edit
the data for existing sites.
Select “New” to create a new site. The following will appear:
The first line, which must contain a unique site number used to identify the
site. The BluFlame will automatically assign a free site number.
All additional free-form text lines, which can contain, for example, a name
and address.
Deleting sites
In the “Sites administration” menu option, you can individually delete the
sites being displayed by selecting “Delete” or delete all sites at the same time.
You will need to confirm the prompt that appears.
8.4 TRANSFERRING DATA WITH AN SD CARD
CSV is the format used to transfer data. The file used is a text file in which
each line represents a data record and the individual entries (fields) in the
data records are separated with a semicolon (;) (see below for an example).
This format ensures that the information can be read and generated in
spreadsheet programs and databases (e.g., Microsoft Excel™ or Access™).
There are also other programs that can work with this format, as it is
widespread and easy to implement.
The following functions are available in Version 1.11 and higher:
• Importing sites
• Exporting sites
• Exporting flue gas measurements
Importing sites
With this function, the BluFlame can import a site master from a PC or from a
dierent measuring device. The filename for the master must be “anlagen.csv”.
Moreover, the file must not have any column headers, i.e., the first line must
already contain payload data. Every line that is not empty and that does not
start with a semicolon (both result in the first field (Site No.) being empty,
which is impermissible) will be imported.
For each line / data record, the max. number of fields that will be imported
are the first 9, and the max. number of characters that will be imported per
field will be 24 (characters beyond this limit will be truncated).
Site examples
SITE USED TO WARN OF A HAZARD SOURCE OF ANY KIND
9 Fields A1-F1;A1-F2;A1-F3;A1-F4;A1-F5;A1-F6;A1-F7;A1-F8;A1-F9
2 fields (1 and 4) A4-F1;;;A4-F4
1 Field A5-F1
Sample lines with 3 invalid sites and reason for error in parentheses
;A1-F2;A1-F3;A1-F4;A1-F5;A1-F6;A1-F7;A1-F8;A1-F9
(semicolon at the beginning) (empty line)
During the import, the device will not check for duplicate site
numbers (line 1) within the file or between the file and sites
already found in the BluFlame. And while the BluFlame can handle these
duplicates without any problem, they may make it impossible later on to
determine which site certain measurements correspond to in PC programs.
After a successful import, the BluFlame will mark the site file. If you attempt
to import the same file from the same device later on, a prompt with a red
font color will appear.
Exporting sites
You can use this function to back up a site master to an external PC or, if
you have manually changed site data in the BluFlame (e.g., updated phone
number), to transfer it to an external PC program.
You can also use the export function to transfer a site master to a different
measuring device (BluFlame).
The filename for the exported file will be “ANLxxxxx.csv”, where xxxxx is a
consecutive five-digit number with leading zeros. If you want to import the
site master into another measuring device, you will first need to rename the
file “anlagen.csv”.
Exporting flue gas measurements
You can use this function to export saved flue gas measurements to an
external PC.
This function is not suitable as a backup function or as a way to
transfer measurements to other measuring devices, as these
measurements cannot be imported afterwards.
The filename for the exported file will be “EMIxxxxx.csv”, where xxxxx is a
consecutive five-digit number with leading zeros.

16
The file will include column headers and will contain the site No., date/time,
measuring program, fuel, CO
2
max, O
2
reference value, all readings with units
that are also available in the BluFlame, e.g., smoke numbers, derivatives, and
boiler temperature.

Or by deleting all measurements for a measurement type
You will need to confirm your decision before the measurements are
actually deleted.
Transferring measurements to a micro SD card
The BluFlame offers the option of transferring all stored measurements to a
micro SD card.
Confirming with the F2 button will start the data transfer/export to the SD card.
During the transfer, the display will show “please wait.” If there is no micro
SD card present, or if the card is write-protected or faulty, an error message
saying “Error. Writing to the memory card is not possible” will appear.
The data records will be stored as a CSV file (e.g., EMI01032.csv) on the micro SD card.
The filename will consist of a consecutive number assigned by the BluFlame.
In the file, each measurement will be identified with the corresponding site
number and the date and time when the measurement was carried out.
You can edit this file on an external PC with the use of a spreadsheet
program such as Microsoft® EXCEL or OpenOffice® Calc.
If you run into any problems using your computer programs, please
consult the corresponding software documentation.
Extras / Settings
The BluFlame originally comes with software that is configured with default
settings that in most cases will cover your needs. Nevertheless, these
settings can be customized flexibly as required for your specific needs to a
large extent.

9.3 SERVICE VALUES
If the BluFlame has a fault (e.g., message during
calibration: “O
2
sensor not OK”), it will usually be
possible to pinpoint this fault on the service
screen.
The screen will show the service values for all
sensors. If there is an error message, contact our
After-Sales Service Department. Our After-Sales
Service technicians may then ask you to provide
them with certain service values so that they
can pinpoint the fault.

17
9.4 LEAK TEST
When running a leak test, the BluFlame will test the system (incl. the
condensate trap/the gas cooler) all the way to the probe tip for leaks.
To do this, the internal gas pump will generate a vacuum that will be measured
with the integrated draft sensor and monitored for a period of 10 seconds.
The magnitude of the observed pressure drop will then be used to determine
whether the system has any leaks.
Running a leak test
Clean the probe tip before the leak test (if there are any deposits
on the surface, the test cap will not create a seal).
• Slide test cap #61382 (for probe tubes with a diameter of 8 mm) over the
probe tip.
• Select the following: Main menu Instrument leak test.
If the leak test is not passed, check the probe and its tubing, as well as the
condensate trap.
If you cannot find any leaks on these external parts, the BluFlame will need
to be checked at a service location. To find your local service location, please
visit www.accutools.com.
9.5 DEVICE INFORMATION, WARRANTY
MANAGEMENT, AND IDENTIFICATION NUMBER
• Select the following: Main menu ➡Menu: Extras ➡ Device info
in order to show the device information.
Maintenance and Care
Acid from the condensate
Chemical burns may result due to contact with slightly acidic
liquids from the condensate.
• If you come into contact with acid, immediately rinse the area thoroughly
with water for an extended period of time.
10.1 CLEANING AND CARE
The BluFlame requires very little maintenance in order to remain in good
condition in the long term:
• After every measurement, disconnect the gas sampling line from the
BluFlame so that it can dry off.
• If soiled, clean the probe and the probe tube.
• In the event of extended periods of non-use, first charge the battery fully.
Then charge the battery every 8 weeks.
• Replace the pocket star filter on a regular basis.
• Replace the pocket star filter after cleaning it 4 – 5 times.
Frequent measurements will result in a high degree of soiling;
accordingly, replace the pocket star filter on a regular basis.
10.2 MAINTENANCE
In order to ensure that the device is kept in good condition, we recommend
arranging for an AccuTools service location to perform an annual inspection
and a sensor calibration (www.accutools.com).
