6. Mounting and placement of the boiler
The mounting rail (is included) is recommended for mounting the boiler on the wall see
Diagram 6. First fix the rail on the wall
.
On this rail hang the heater unit with the pump and
accessories. The boiler casing is removable and is fixed to the rear panel with screws. It
is necessary before mounting to find a place where the boiler can be serviced without any
obstructions.
If the boiler is installed to an open system the heating water column must produce a
pressure of min. 1bar.
In heating systems fitted with thermostatic heads, water circulation can be completely
closed, and it is necessary to mount a by-pass leading through one heating body, which
is not fitted with thermostatic heads or to use another by-pass.
The use of non-freezing mixtures is not recommended due to their properties which
are not suitable for boiler operation – particularly reduction of heat transfer, high expansivity,
aging, damage to rubber parts. If there is no other possibility of reliable prevention of
freezing of the heating system, then non-fulfilment of some functional parameters or
eventual boiler failure caused by usage of non-freezing mixtures can not be included as a
area of warranty.
Prior to the final mounting of the boiler it is necessary to flush the boiler distribution system several times with
pressure water. Older, already used systems should be flushed in the direction which is opposite to the direction of
the heating water. In new systems all heating bodies should be flushed with pressure water to remove preserving
agents.
Placement of a sediment catcher before the boiler is recommended (i.e. to the return heating water piping). The
sediment catcher should allow regular draining without having to drain a lot of heating water. The sediment catcher
can be combined with a filter. A filter itself with a sieve, however, is not sufficient for protection.
The warranty does not apply to clogging of the boiler by heating system contaminants and to failures caused by
such a clogging.
Note:
The filter and the sediment catcher must be checked and cleaned regularly.
Before a filling the heating system of water is a requirement to check a pressure in an expansion tank. An
additional completion of the pressure from among 1-1,3 bar is made if necessary.
6.1. Wiring
The user has to arrange a power electric connection with a main switch for heating, protection, and other
adjustments of the house wiring including its initial revision and application for electricity supply.
Bushings for mains connection, connection of a spatial controller, a general remote control, or a cascade connection
