•
Reset the auger mode. Navigate to Auger Mode ‘No’ using the ‘Enter key’ and activate
a reset using the ‘Up Arrow’ key or ‘Down Arrow’ key (Figure 90).
STEP 7 - Flue gas analysis
Now the fuel regulation function has been checked, flue gas analysis can be conducted. The
appliance will need to remain in the modulation sequence throughout this process (see Figure
17), and in Powerband 2 or higher. The flue gas temperature must also be at least 80°C.
•
Using a flue gas analyser inserted into the flue system, check the CO
2
content and the
flue gas temperature once the appliance is hot and in a stable operating condition.
•
The test point for flue gas measurements is provided on the flue extension starter
piece (See Figure 66). Remove the M10 threaded plug and insert the analyser probe.
IMPORTANT: Testing while the appliance is still relatively cold gives inaccurate results and
leads to incorrect adjustments being made.
The CO
2
level is controlled by the intake fan and is self-correcting and should not require
alteration at commissioning. However, if the CO
2
level is continually outside the range of 6% to
14% please contact Warmflow.
If the flue gas temperature is above 160°C or a CO value above 400ppm continually please
contact Warmflow. It is normal for CO, CO
2
, O
2
and NOx values to fluctuate during operation.
Please refer to Table 1 for flue gas temperatures at maximum and minimum outputs.
Following flue gas analysis, ensure that the M10 threaded plug is re-inserted into the test
point on the flue extension starter piece.
