Sampling The Flue Gas - Kane 905 Manual

SAMPLING THE FLUE GAS

Once the automatic calibration procedure has been completed and the
specific fuel has been selected (See SELECT menu) the probe can be
inserted into the desired sampling point.
It is recommended that the sampling point be located at least two flue
diameters downstream of any bend and that the probe tip is in the centre
of the flue. With balanced flues and other domestic units the probe
should be positioned far enough into the flue so that no air can 'back
flush' into the probe. This will be indicated by a low oxygen reading
and/or a low 'Poison Index' reading.
The probe depth stop cone provided with the instrument allows the probe
to be used in holes whose diameters range from 8 mm to 21 mm (
13
/ inch).

The standard probe is rated at 650C (1202
1200C (2200F) can be accommodated using an optional high
temperature probe.
TIP: To conserve battery power, switch off the pump when you are not
taking a measurement. Use the
pump.
