Testing the combustion parameters
Test the combustion parameters with the boiler closed.
Testing the combustion air
- Remove the screw from the r.h. test port.
- Open the gas shut-off valve.
- Insert the test probe.
- Start the gas fired condensing boiler and turn the heating
water temperature selector to the emissions test symbol
(illuminated status display ring flashes yellow).
- Test the temperature and CO
2
value.
The balanced flue pipe is not sound, if the CO
2
content is >
0.3 %; rectify the leak.
- After the test has been completed, switch off the boiler,
remove the test probe and close the test port. Ensure the
screws seal tightly.
Testing the flue gas parameters
Flue gas can escape into the installation room, if
the test port is not sealed. This results in a risk of
asphyxiation.
- Remove the screw from the l.h. test port.
- Open the gas shut-off valve.
- Start the gas fired condensing boiler and turn the tempera-
ture selector to the emissions test symbol (illuminated status
display ring flashes yellow).
- Insert the test probe.
- Test the flue gas values.
- After the test has been completed, remove the test probe
and close the test port. Ensure the screws seal tightly.
