9.5. Performing leak test
With the leak proof test, the system is checked by the device (incl. the
condensate separator) up to the probe spike on undensity. The internal
gas pump generates in addition a subpressure which is measured over
the built-in draft sensor and is observed for a period of 10 seconds.
Based on the decrease of pressure the leakness of the system will be
determined.
Operation:
► The leak proof test cap # 61382 (for probe tubes Ø 8 mm) must be
put on the probe spike.
With dirt and soot particles on the probe tube the test
cap will not seal properly.
► The probe tip must be cleaned before you start this
test!
► Go to the Extras menu.
► Select Leak proof test.
► Press OK.
The menu Leak proof test appears.
► Ensure that the leak test cap is plugged in.
Pressure is established.
A 10-second test is running.
A message appears whether the leak proof test was passed or not.
► Remove the proof test cap.
