installation
a
Caution!
Flush the heating system thoroughly be-
fore connecting the appliance!
By doing that, residue such as welds,
cinder, hemp, putty, rust, rough dust and
similar substances are removed from the
pipes. Otherwise such substances can be
deposited in the appliance and cause
damage.
a
Caution!
To prevent leaks, take care that no me-
chanical stresses are created on the
connection lines!
- The pipework installation must be carried out in ac-
cordance with the dimensional and connection draw-
ings in Fig. 4.1.
- The installation must be performed by a specialist fit-
ter.
- The applicable regulations must be observed during
the installation.

Note
Air in the heating installation leads to
impaired operation and reduces the heat-
ing output. Fit bleed valves as required.
