7.4. Connecting the boiler to the heating
installation.
Such connection must be

When the boiler is connected to a heating
system, it is mandatory to install a 3 bar
relief valve and expansion vessel. No shut-
off fittings may be installed between the
relief valve, expansion vessel and boiler.
It is mandatory to install a three-
way valve (Laddomat or similar)
or a four-way mixing valve which
to ensure that the temperature
of the heating medium fed into
the boiler from the heating
installation is at least 65°С
.

Cause
Solution
Installation damage
Due to unsealed connections
Install the connecting piping strain-free to the boiler
connections.
Due to freezing
If the heating installation, including the piping network, has
not been built frost-proof, we recommend that you fill the
heating installation with a liquid which has low freezing point
and corrosion protection and antifreeze agent.
Boiler water too hot, heating bodies too cold
1. Hydraulic resistance is too
high.
2. Air in the system
3. Inoperable circulation pump
Make sure the circulation pump has been properly selected and
the heating installation is of the proper dimensions. (You must
contact your installer.)
