Additional information:
Sprint Pro is designed to meet the requirements of
EN50379-1 and EN50379-3 and to support the work-
ing practices defined in Standard BS7967.
It is highly recommended that users are fully con-
versant with local regulations when using a flue gas
analyzer for servicing or installing a boiler system.
When performing any CO measurements ensure
the unit is zeroed in clean air. A suitable location
for sampling clean air will be outside of the build-
ing where the boiler system is installed, away from
exhaust vents.
Sprint Pro offers a timed let-by/tightness test.
If the Sprint Pro has not been used for more than
6 months it should be put on charge for at least 4
hours without use. This will allow the oxygen chan-
nel and if present the NO channel, to read correctly.
Failure to do this may cause the oxygen measure-
ment, the NO measurement and any calculations
depending upon them to be incorrect.
Magnets on the reverse of Sprint Pro can be used to
place the Sprint Pro in location on the boiler system
for easy hands-free operation.
Diagnostics and usage data from Sprint Pro is acces-
sible at service and can be viewed at service centers.
We reserve the right to update and enhance the soft-
ware at times of service without prior knowledge.
WARNING: Take care not to place items which may
be sensitive to strong magnetic fields near this mag-
net, e.g. credit cards or magnetic storage devices like
computer hard drives.

Once the sensor is ready for use, pressing the
‘Continue’ (middle) button will acknowledge this
warning and allow normal instrument function.
Pump
Sprint Pro runs the internal pump during purge and when certain tests are
selected, and during and after some tests. A rotating purge icon will appear on
the screen when purging. To save on the battery life, Sprint Pro will turn off
the pump when it is not required.
When the pump is running ensure the exit gas exhaust is not blocked and do
not breathe in the exhaust gases. The purge function is often used by Sprint Pro
to put clean air over the sensors prior to turning off. This is ideal for realizing the
full potential lifespan of the sensors, especially the CO sensor filters.

Performing tests Sprint Pro
III. Performing tests
Important:
Sprint Pro must only be used with the Sprint Pro flue probe assembly
and always with the water trap and filters in place.
Please ensure the flue probe is connected before switching on your
Sprint Pro unit. Ensure the water trap is empty and is fitted in the right
direction. Always start in clean air and ensure that the gas exhaust is
not blocked. Do not insert the probe into the flue until after the zeroing
process is complete.
Note: Sprint Pro will switch off the pump when not performing tests or purging.
Zeroing process
Following Switch on Sprint Pro will require a ‘zero’ before selection of any of
the following tests: Flue Gas Analysis, Room Safety test, Appliance Sweep test
or Ambient Air Monitor test.
Ensure you are in clean air before proceeding with the zeroing process.
The zeroing process will then not be required when selecting these menu
options unless Sprint Pro is subsequently switched off and on.
Press the key to confirm you are in clean air. The Sprint Pro will then perform
a ‘zero’. Provided the zeroing process is successful Sprint Pro will display the
menu option chosen.
Tip: To ensure the zero is performed in clean air undertake the zeroing process outside
of the building or well away from the heating appliance to avoid any potential gases in
the vicinity affecting the zero process.
This is especially important for Sprint Pro 6 because of the additional carbon dioxide
sensor.
If a CO2sensor is fitted and it is not possible to undertake the zeroing process in clean
air a CO2scrubber can be utilized, please see Analyzer Settings section.
Warning: During testing, ensure the combined filter and water trap is not blocked or
full. Failure to do so may result in an error message.

Note: for personal safety a carbon monoxide (CO) alarm will activate at 350ppm. This will
deactivate when CO levels drop below 200ppm. This is to inform the user of potentially
hazardous exhaust levels.
To end test press the ESC key.
Note: The minimum test duration should exceed both the time taken for burners
to heat up, during which the CO and NO produced may not be representative of
subsequent operation, and also the time needed for the boiler output to stabilise. Both
these periods are less than 5 minutes for most boilers hence flue test duration should
be a minimum of 5 minutes and a maximum of 30 minutes.
Values of Oxygen (O2), carbon monoxide (CO), nitric oxide (NO), pressure, inlet
temperature and flue temperature are measured and displayed by Sprint Pro.
Values of carbon dioxide (CO2), carbon monoxide to carbon dioxide ratio, excess air (XS
Air), efficiency, NOx and net temperature are calculated and displayed by Sprint Pro.
Note: When using Sprint pro with oil or solid fuel boilers, to ensure correct operation
and prolong the life of the filters, testing guidance in CD/11 (Oil Firing, Servicing and
Commissioning standard) should be followed.
CD/11 recommends undertaking initial tests to check cleanliness of combustion
prior to flue gas analysis testing. Thus please light the burner and allow it to run
for at least ten minutes to establish settled conditions. At this time take a smoke
spot reading at the test point provided. Adjust until a satisfactory figure is obtained.
Now it is possible to carry out a flue gas analysis test.
