10.2 Possible Placement
The installation and operation of the boiler shall comply with all requirements of Č SN 06 1008.
The boiler placement shall comply with the project documentation. The flue gas exhaust shall comply with the valid regulations. Ports of
individual pipes for supply of combustion air and discharge of flue gases shall be located in such a way that they are located inside a square
with a side of 50cm by the boiler. The boiler can be placed on a wall with ensured loading capacity only.
At least 0.2 m shall be left free beside the boiler and above the boiler and at least 1 m shall be left free in front of the boiler for assembly and
repairs.
The boiler also can be placed in a room with the basic environment according to
Č SN EN 33 2000-1 ed 2.
Fig. № . 10 Main dimensions of the boiler
Placement of the boiler with respect to fire regulations:
A safe distance from flammable materials:
−
when installing and operating the boiler it is necessary to keep a safe distance of 200 mm from the materials of combustibility grade A1,
A2, B and C (D);
−
for easily combustible materials of combustibility grade E (F), which quickly burn and burn themselves even after removal of ignition
source (such as paper, cardboard, asphalt and tar paper, wood and woodfiber boards, plastics, floor coverings) the safe distance has to
be doubled, i.e. to 400 mm;
−
safe distance should be doubled also where the grade of reaction to fire has not been proved.
A safe distance from surfaces of materials with individual degrees of flammability and information of the flammability degree of common building
materials, if necessary, for appliances which can be operated in the immediate vicinity of walls made of flammable materials will be defined with
the maximum permissible temperatures of surface or wall temperature increase according to
Č SN EN 13 501 – 1 + A1.

polyethylene, PVC,…
10.3 Boiler Installation
Using the installation stencil (the stencil is printed at the bottom of the carton packaging of the boiler) attach the enclosed bracket to the wall
using 3 pieces of dowels with diameter of 8 mm and bolts. Mount the VIADRUS K4 boiler on the bracket and using the marked outlets the boiler
is connected to the heating system incl. hot water (if used) and gas distribution pipe according to Fig. no. 11. The connection of condensate
outlet should be in compliance with the effective valid
Č SN and EN standards. Then the flue gas exhaust is connected according to the project
documentation. Remove the protection foil from the front cover.
