1.3.1 Mechanical Connections
The CFC10 and the pressure sensor (DPT-A) are installed in the boiler room. In flue gas
systems with several fireplaces, the measuring probe (MP) should be installed between the
last fireplace and the chimney fan or as close as possible to the chimney fan inside the flue
gas pipe or the collecting pipe of the flue gas system. The measuring probe (MP) is
connected to the pressure sensor through the silicone tube and is placed below the
installation site of the pressure sensor. For installations in vertical flue gas pi pes, please
note the arrows on the measuring probe. In horizontal flue gas pipes, the measuring probe
has to be installed at an angle of at least 5% as shown in fig. 5.
Do not bend or damage the tubes when connecting or laying them. Leaky tubes and
connections will cause the control to malfunction.
The tube should ascend from the measuring probe to the pressure sensor so that no
condensate can accumulate in the tube.

Please use the connection P2 (-) on the differential pressure sensor. This connection is
designed for negative pressure measurements.
