- Remove front and top casing.
- Pivot the control unit downwards.
- Insert the oil pressure gauge into the pump's pressure gauge test port.
- Remove the cap from the l.h. "ue gas" test port.
- Insert the test probe of the CO
2
measuring instrument into the "ue gas" test port.
(approx. 70 mm).
- Turn the heating water temperature selector to "Emissions test"
(illuminated signal ring as status indicator ashes yellow.)
- Measure the CO
2
content and compare it against the values given in the stage 2
table adjacent.
- If required, set the CO
2
content with the stage 2 pressure regulating screw using a
4 mm Allen key in accordance with the table.

- Check location and seating of the installation.
- Checkthefuellevelintheoiltank.
- Check all connections and component links for leaks.
- If tightness cannot be ensured then there is a danger of water damage.
NB
- Fit casing.
- Check that all ue gas accessories have been correctly installed.
- Open the shut-off valves on ow and return.
- Open oil shut-off valves (tank, oil line, lter).
- Switch ON the heating system emergency stop switch.
- Switch ON the system ON/OFF switch on the control unit.
- Remove cap from r.h. test port (inlet air).
- Insert test probe 2 cm.
- Turn DHW temperature selector to 1.
- Turn heating water temperature selector to "Emissions test"
(illuminated signal ring ashes yellow).
- After a pre-purge time of approx. 25 seconds, the pump starts up and opens the
solenoid valve. The supplied fuel oil reaches the nozzle and a ame is established.
- The burner enters a fault state if, during commissioning, the oil pump does not supply
sufcient oil during the pre-purge time. Repeat the burner start by pressing reset.
- Measure temperature and CO
2
in the inlet air and enter the values in the commissioning
report in chapter 24.
- The ue is not gas tight if the CO
2
content > 0.2%; rectify the leak.
- Terminate the emissions test mode by turning the temperature selector back to its
original position.
- If emissions test mode is not reset manually, the appliance switches back to the
original operating mode automatically after 15 minutes.
- Remove the test probe and close the test port. Ensure the cap is seated rmly.
