2.3.7.2 BASIC REQUIREMENTS FOR INSTALLATION OF H
2
O
The Senso M H
2
O / Piko H
2
O must only be mounted in thermostatically pro-
tected systems in accordance with DIN 4751 or DIN EN 12828. All lines to the
heating network must always be designed so that they can be detached (e.g.
as threaded fitting).
Before the stove is placed in service, it must be filled and ventilated on the
heating side (heating network) and water side (thermal discharge safety
device, safety heat exchanger). After the filling process, check all hydraulic
connections for leaks.
Operation without a water-side connection results in irreparable dam-
age and invalidates any warranty claims!
In the direct vicinity of the Senso M H

O / Piko H
2
O, a type-tested safety valve
(identification letter H) with an activation overpressure of max. 3.0 bar
must
be mounted in the flow line. A shut-off possibility must not be integrated in the
system between the safety valve and the Senso M H
2
O / Piko H
2
O. This could
render the safety device inoperable. Moreover, all necessary safety devices
must be integrated in the entire system in such a manner that safe operation is
ensured. A separate safety valve must also be installed, if such a safety valve
is installed at a different point in the entire system (comply with TRD 721!).
When installing, the instructions in the installation and operating manuals of
the installed heating-related components/additive components must always
be complied with!
2.3.7.3 THERMAL DISCHARGE SAFETY DEVICE (TAS)
Since the heating of the Senso M H

O / Piko H
2
O is not automatic and can be
quickly switched off, according to DIN 4751 – Part 2 and DIN EN 12828, the
stoves are equipped with a thermal discharge safety device. For this, a safety
device (safety heat exchanger) is integrated in the Senso M H
