4 Planning and installation – Installing the heating system

39

4.5 Installing the heating system

The heating system will be commissioned by specialists from HDG
Bavaria or from an authorised HDG partner and a qualified electri-
cian.

Danger!

Risk of material damage and injury due to incorrect installation

Installing the system requires comprehensive specialist knowledge.
If installed by untrained persons, the heating system can be dam-
aged and persons may be injured due to secondary damages.

Only allow authorised specialists to perform the installation.

Danger!

Dangerous electrical current or voltage

Working on live components can result in an electric shock.

Switch off the mains supply to the heating system during the instal-
lation.

Important!

When laying the pipelines, observe the minimum required clear-
ances.

✎

See section “4.1 Dimensions” in this chapter.

Important!

Due to the noise, we recommend acoustic insulation measures for
components which are in contact with the floor, wall or ceiling of
the heating room.

The following figures and diagrams show the version of the heating
system HDG Compact 25 - 80 with feeding system TBZ 150 on the
left side of the boiler.

Please keep this in mind if your version has a feeding system on the
right.
