- Remove front and top casing.
- Remove the cap from the r.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 program selector switch on the BM module 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
below.
- If required, alter the CO
2
content with parameter HG00.
- Modifying the parameter HG00 has also adjusted the speed for stage 1. For
checking purposes, the boiler must be set to stage 1.
- Switch HG28 burner operating mode from 2(two-stage) to 1(single stage).
- Measure the CO
2
content and compare it against the values given in the stage 1
table below.
