3.1 Turning On
Always: - Before turning on please ensure
that the In-Line Pump Protection Filter
(shown across) is connected to the Gas
Sample Port (see 2.2 or 2.4).
**THIS MUST REMAIN ON THE UNIT
AT ALL TIMES.**
Failure to do so may result in pump failure
and will invalidate the warranty.
Press the Power Key for approximately 2 seconds and the TPI 717R will
start up and display ALL Segments on the display for approx. 1 second. The
717R will then enter its 30-second purge period, briefly displaying the Software
Version & Instrument Serial Number, before continuing with the countdown where
upon the following screen will be displayed.
The instrument should ALWAYS be turned
on in a clean air environment as the 30
second purge will attempt to set the
Carbon Monoxide level to 0 ppm and the
Oxygen to 20.9%.
If there is insufficient clean air in the sensor
chamber after the 30 second purge period an
error indicating this may be displayed, please
see troubleshooting guide (appendix D) for
appropriate remedy. If the error is still present
after attempting the suggested remedy please
call the

4. THE 6 FUNCTIONS
After the 30-second countdown the instrument is ready to take Flue Gas,
Temperature or Pressure readings and will Display the following Screen.
You are now ready to take Flue Gas Analysis
Readings. Please continue on with the manual from
Section 4.1 (below) which will guide you through the
various Analysis Screens.
However, if you do not wish to perform a Flue Test at
this moment Press the Func/Backlight Key
and move onto Section 4.2 of the manual.
At any time you can activate the Backlight by holding down the
Func/Backlight Key for 2 seconds.
4.1 Function 1: - Flue Gas Analysis
Ensure you have connected the Temperature Sampling Probe complete with
In-Line Water Trap Bowl Filter to the In-Line Pump Protection Filter (See 3)
which should ALWAYS be connected to the Gas Sample Port (see 2.2 or 2.4)
and that the ‘K’ Type Thermocouple Plug is in Thermocouple Socket (ch1)
(see 2.4). Also ensure that a ‘K’ Type Air Probe is connected to
Thermocouple Socket (ch2) (see 2.4) in order to calculate efficiency.

Your temperature-sampling probe comes complete with an In-Line Water Trap
Bowl Filter as standard.
This consists of a Particle Filter in
the Bowl Compartment and a Disc
Filter in the Lid (as shown in the
diagram across). The Disc Filter in
Lid will prevent any excessive water
from entering the 717R Combustion
Analyser if used correctly.
If you are working with OILthen you MUST ensure that you also use the optional
Oil Filter as shown below. Failure to do so will result in erroneous readings.
If any of the filters become excessively dirty or blocked then the
following screen will be displayed as a warning and no further
readings will be able to be taken until either the dirty filters are
replaced or the blockage removed:-
The 717R will also give off an audible Beeping Alarm
to warn that a “FLo Err” is being detected

WARNING: - Ensure that the In-Line Water Trap Bowl Filter hangs in a vertical
position whilst readings are being taken, particularly if water is visible (see below).
Failure to comply may result in damage to the instrument and will invalidate
the warranty.
WARNING: - There is ONLY one correct way to connect the
‘K’ type thermocouple plug into the socket (see 2.4). The
thermocouple plug is designed with one thick (negative) and
one thinner (positive) prong. Forcing the plug into the socket
the wrong way round may result in damage to the instrument.
Failure to comply may result in damage to the instrument
and will invalidate the warranty.
Pressing the Enter Key will take you through the following Flue Gas
Analysis Screens
4.1.1 Screen 1
Displays Carbon Monoxide (CO) reading in parts per
million (ppm)
Displays calculated Carbon Dioxide (CO2) figure in
percentage (%)
Displays calculated CO/CO2(Ratio) figure
Pressing the Up Arrow Key will toggle between
the Fuel Options
Pressing the Down Arrow Key will toggle
between the Efficiency Options

4.1.2 HIGH CO ALARM
Should the CO reading rise above 2,000ppm a continuous series of Alarm Beeps
will be heard. This Alarm alerts the user that there is a high concentration of CO
and that there may be a potential problem with the appliance. The instrument will
continue to monitor CO up to 10,000ppm but the longer the probe is left attached
to the instrument sampling at these high levels the longer the recovery time back
to ambient air before the instrument will be able to be switched off (see 4.1.7 –
Failsafe Turn Off).
4.1.3 Screen 2
Displays Oxygen (O2) reading in percentage (%)
Displays calculated Excess Air (X Air) figure in
percentage (%)
Displays calculated Efficiency (Eff.) figure in percentage
(%)
Pressing the Up Arrow Key will toggle between
the Fuel Options
Pressing the Down Arrow Key will toggle
between the Efficiency Options
4.1.4 Screen 3
Displays Carbon Monoxide (CO) reading in parts per
million (ppm)
Displays Oxygen (O2) reading in percentage (%)
Pressing the Up Arrow Key will toggle between
the Fuel Options
Pressing the Down Arrow Key will toggle
between the Efficiency Options

4.1.5 Screen 4
Displays CO air free calculated reading
Pressing the Up Arrow Key will toggle between
the Fuel Options
Pressing the Down Arrow Key will toggle
between the Efficiency Options
4.1.6 Screen 5
Displays Temperature reading of T1 in degrees
Centigrade (ºC)
Displays Temperature reading of T2 in degrees
Centigrade (ºC)
Displays the Differential Temperature (Diff.) between T1
and T2 in ºC
‘oPEn’ will be displayed if no ‘K’ type probe is
connected to the thermocouple socket
Pressing the Up Arrow Key will toggle between
ºC and ºF
4.1.7 CO above 15ppm (Failsafe) Protection Beep
The 717R will not allow the user to either Turn the instrument OFF or to move to
another Function whilst the CO level is above 15ppm. A short beep will be heard
should the user attempt either of the above with the CO above 15ppm.
This is a Failsafe Feature of the 717R to protect the instrument from giving false
readings when next turned on. The 717R should be run in a clean air environment
with just the In-Line Pump Protection Filter attached until the CO level drops
below 15ppm. The 717R will then be able to be moved to a different function
screen or be turned OFF.

4.2 Function 2: - Temperature Reading
The pump will stop running when in this function
Remember:- It was the Function Key that got you here!!!
Ensure you have a ‘K’ type probe connected to one or both of the
thermocouple sockets T1 or T2 (see 4.2)
WARNING: - There is ONLY one correct way to connect the
‘K’ type thermocouple plug into the socket (see 2.4). The
thermocouple plug is designed with one thick (negative) and one
thinner (positive) prong. Forcing the plug into the socket the
wrong way round may result in damage to the instrument.
Failure to comply may result in damage to the instrument
and will invalidate the warranty.
4.2.1 Screen 1
Displays Temperature reading of T1 in degrees
Centigrade (ºC) or degrees Fahrenheit (ºF)
Displays Temperature reading of T2 in degrees

ºC and ºF
‘oPEn’ will be displayed if no ‘K’ type probe is
connected to the thermocouple socket

4.3 Function 3: - Pressure Testing
The pump will stop running when in this function
Remember:- It was the Function Key that got you here!!!
Ensure you have Pressure Sampling Tube connected to one or both of the
Pressure Ports (see 2.2 or 2.4)
4.3.1 Screen 1
Displays Pressure reading in either millibars (mbar),
kiloPascals (kPa), or inches of Water (inH2O)
Pressing the Up Arrow Key will scroll through
mbar, kPa and inH2O
Pressing the Down Arrow Key will Zero the
Pressure reading

4.4 Function 4: - Tightness/Let By Test
