2.8.2 BASIC REQUIREMENTS FOR INSTALLATION
The ambiente a4H
2
O/a6 H
2
O should only be installed in systems with a ther-
mostatic safety device to DIN 4751 or DIN EN 12828. The connecting pipes
to the heating system should always be laid in such a way that they can be
disconnected (e.g. screwed connection).
Before using the stove for the first time, both the heating components (heat-
ing system) and the water components (thermal discharge safety device,
safety heat exchanger) must be filled and vented. After the filling process,
check all hydraulic connections for leaks.
Operation without a water-side connection results in irreparable
damage and invalidates any warranty claims!
A type-tested safety valve (coded H) with a threshold pressure of max. 3.0 bar
should be fitted in the flow pipe immediately next to the a4H

O/a6 H

O. No
shut-off devices must be integrated into the system between the safety valve
and the ambiente a4H

O/a6 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!).
The installation and operating instructions for the heating components / addi-
tional components included in the system must be read and observed when
installing the stove!
2.8.3 THERMAL DISCHARGE SAFETY DEVICE (TDS)
As the ambiente a4H
2
O/a6 H
2
O heating system cannot be quickly switched
off automatically, the water heat exchanger must be fitted with a thermal
discharge safety device according to DIN 4751 Part 2 or DIN EN 12828. A
safety device (safety heat exchanger) to prevent overheating is integrated into
the ambiente a4H
2
O/a6 H
2
O for this purpose. This safety device must not be
used to heat water.
The thermal discharge safety device is not pre-assembled to protect it during
transport and installation. It will be found inside the firebox at delivery and
should be fitted to the correspondingly labelled connection. After that, the
capillary and adapter should be screwed on to the thermal discharge safety
device. This has been tested and approved for a minimum water throughput
of 900 L/h.
The following instructions must always be complied with for the installation, so
