Draft (fine draft measurement)
The fine draft measurement checks whether the outlet pipe can also feed out the exhaust air created by
the combustion plant using the draft that arises. For this measurement, you must disconnect the probe
hose from the gas connection and reconnect it to the hPa connection (as per illustration).
⇒
Feed the special fine draft probe or flue gas probe into the chimney.

Draft -0.05 hPa
-0.51mmH2O
You can now read off the fine draft. The negative pressure is measured in hPa (1 hPa = 1 mbar) and
mmH
2
O (1 mmH

O = 0.098 hPa) and displayed with a minus sign (-).
If the display shows only one figure, you have not changed the hose connection over.
⇒
Remove the measuring probe and reposition the probe hose as described above.
