8. CENTRAL HEATING CONNECTION
The pipe register resp. the double shell must be rinsed prior to commissioning in order to remove any possible contami-
nations (e.g. scale) from the heating circuit. The heating water must be treated in accordance with the national regulations
and standards (e.g. ÖNORM H5195-1) during commissioning and comply with the regulations.
Water heater with register
The bare-tube heat exchangers installed in the storage tank can be connected to a water heater if the pressure and tem-
perature correspond to the data stated on the specication label. Forced circulation using a pump is required.
When installing a water heater with register a shut-off member must be installed in the ow line to prevent back-heating
into the heating circuit when the central heating and heat pumps are turned off or for electrical operation.
The outgoing and return ow must, however, never be shut off, since otherwise the water in the register cannot expand
and three is a risk of damaging the water heater.
9. IMPORTANT INSTALLATION NOTES
When installing the appliance, follow the dimensional drawings and any included caution labels.
NOTE: Be sure to take into account the weight of the water heater lled (with the rated capacity) when selecting a moun-
ting location so as not to overload the bearing area.
For acceptable distance from combustion devices, refer to the manufacturer’s documentation as well as the prevailing
codes.
If a water heater is tted with additional cladding, or is located in small, narrow areas or between walls, be sure that all
connections (water ttings, electrical connection space and any installed heater) remain freely accessible and that no heat
can accumulate. A clear area of 500mm must be provided for a heating ange.
When selecting and arranging the materials used for installing the appliance, use caution and consider possible electro-
chemical reactions (mixed installation!). The pipelines must be potential-compensated according to DIN 50927.
This type of corrosion results in formation of corrosion elements. In corrosion elements there is a voltage present between
the anode and cathode area. The resulting processes are mutually dependent, but can take place at various distances
from each other. Corrosion elements may occur due to differing potentials, as is the case with contact corrosion. This
means various metals come into electrical contact with each other through an ion-conducting medium (water).
If especially aggressive water is present which requires installation-side special solutions, the possible necessity of special
versions of the water heater should also be considered (ask one of our representatives or contact us directly).
Non-observance of this specication may be considered improper use and result in voiding of the warranty.
