▶ Make sure that the boiler can release its heat.
▶ Insert the lance of the flue gas analyser 10 cm into the test point.
▶ Operate the appliance.
▶ Open the menu Function check > Burner.
▶ Start the Function check by setting the value to 100%.
▶ Measure the CO content.
▶ Determine and eliminate the cause of the potentially high CO content.
▶ Make a note of the CO content in the commissioning report ( §
16.6, p. 49).
▶ Measure the CO
percentage.

Measure the of the heat exchanger air resistance
[R
]
0
The degree of contamination can be determined by measuring the air
resistance via the heat exchanger. During the initial commissioning, the
air resistance measured must be used as reference value [R
the subsequent inspection or maintenance, the measurement [R
should be used as an indication of the contamination.
▶ Switch off the appliance.
▶ Remove the front panel.
▶ Remove the cover of the condensation catch pan ( Fig. 38, p. 34).
▶ Open the gas/air ratio test port by turning the adjusting screw
through 2 revolutions ( § 8.3, p. 22).
▶ Set the pressure gauge to"0".
▶ Connect the pressure gauge to the gas/air ratio test port.
▶ Operate the appliance.
▶ Open the menu Function check > Fan.
▶ Start the Function check.
Now the fan is switched on. The burner remains switched off during
this function check.
▶ The air resistance is read-off in Pascal [Pa].
▶ Note the measurement in the measurement report ( § 10.18, p.
38).
▶ Stop the Function check.
▶ Close the gas/air ratio test port.
▶ Reattach the cover of the condensation catch pan.

Reading off the ionisation current
▶ Open the menu Function check > Burner.
▶ Start Function check by setting the smallest possible value.
▶ Open the menu Info > Ionisation current.
▶ Reading off the ionisation current.
The ionisation current must be at least 2 A.
▶ If the value is lower, check the gas/air ratio and the igniter.
▶ Make a note of the value that has been read off [A] in the
commissioning report ( § 16.6, p. 49).
▶ Deactivate Function check.
8.9
Check the (flue) gas tightness
NOTICE
Damage to boiler due to short circuit.
▶ Cover plugs, cables and components when using gas leak detection
spray.
▶ Make sure that the boiler can release its heat.
▶ Operate the appliance.
▶ Open the menu Function check > Burner.
▶ Start the Function check by setting the value to 50%.
▶ Check all gas-carrying components using an approved leak detecting
agent or device.
