Put the side parts of the shell on the consoles (pos. 3) – with the narrower cutout in the front part of the
boiler.
5.
In the rear part of the boiler screw the rear upper part of the shell with insulation (pos.11) and rear lower
part of the shell with insulation (pos.12) to the side parts of the shell by means of tapping screws.
6.
To 2 pc M5 threaded rods welded in the upper part of the shell (pos. 4) put the strip KZL (pos.16)
according to the selected wiring outlet direction and secure with 2 pc M5 nuts.
7.
To the top section of the side parts fit 2 M5 screws in the front part and 2 M5 screws in the rear part it
means 4 pc M5 screws altogether so as to retain the gap of the sheet thickness between the shell and
the screw head
8.
Before mounting the control box put out the perforated section in the upper part of the shell.
9.
Pull the conductors, capillaries of thermostats and thermomanometer through the opening.
10. Put the capillaries of thermostats and thermometer sensor into the basin installed in the top hub of the
front boiler section and secure with the spring of capillaries. Screw the check valve of the manometer
into the bottom hub of the front section.
11. Screw the control box by means of 2 pc screws M6 with washers and nuts to the upper part of the shell
and then put it on the screw heads located in the upper section of shell side parts of the shell and fix by
sliding backwards.
12. Screw the upper rear part of the shell by means of 3 tapping screws to the upper part of the shell.
13. After the burner installation is complete put the front part of the shell with the label VIADRUS on the
screw heads located in the front part of the shell side parts (pos. 3). Before mounting click into 2 pc

15. Filling the heating system with water.
The heating system must be thoroughly flushed in order to wash out all impurities. Water for boilers and
heating system filling must be clear and colourless, with no suspended materials, oil and aggressive
chemicals. Its hardness must correspond to
Č
SN 07 7401 and it is necessary to treat water in case its
hardness is unsuitable. The heating systems with an open expansion reservoir allow a direct contact
between heating water and atmosphere. During the heating season the expanding water in reservoir
absorbs oxygen which increases the corrosive affects and at the same lot of water gets evaporated. It
can only be replenished by water treated according to
Č
SN 07 7401. During the heating season the
water volume in heating system must be kept constant. When refilling the heating system with water it is
necessary to prevent it from air intake. Water from boilers and heating system must never be discharged
