Fig. 5 Pump characteristics
5.4.1.3 Shut-off valves
It is recommended that manual valves should be installed between the fl ow and return connec-
tions to the installation.
5.4.1.4 Valves
It is possible to install mechanical non-return valves. These valves are intended to prevent water-
side short circuiting over the switched-off boiler.
5.4.1.5 Water fl ow protection device
The boiler is equipped with a water fl ow protection device.
The fl ow sensor and the fl ue gas sensor ensure that the protection device gets triggered if the
water fl ow is too low.
