6.2 Possibilities of placement
Upon installation and usage of the boiler,
it is necessary to observe all
requirements of
Č
SN 06 1008.
The boiler has to be placed in accordance
with the project documentation. Flue gases
exhaust has to comply with the valid
regulations. Orifices of separate pipelines
for combustion air supply and flue gases
exhaust have to be located so that they are
placed inside a square with the side of 50
cm at the boiler. The boiler can be only
placed on the wall with a guaranteed
bearing capacity. The following minimum
distances have to be near and above the
boiler: 0,2 m and in front of the boiler 1 m
for mounting and repairs, and with regards
of
fire-fighting regulations. The
manufacturer recommends placing these
products in closed heating systems.
The boiler can be placed in a room with
usual environment according to
EN 33 2000-1 ed 2.
Fig. № . 3 The main boiler dimensions
Boiler placement with regard of fire-fighting regulations:
Safety distance from flammable materials:
−
during installation and at operation of the boiler it is necessary to observe a safety distance 200 mm from
flammable materials with the combustibility grade A1, A2, B and C (D);
−
for lightly combustible materials with the combustibility grade E (F), which quickly burn and burn themselves
even after removal of the ignition source (for example, paper, paste-board, cardboard, asphalt- and tarboard,
wood and fiberboards, plastics, floor cloths) the safety distance is doubled, it means to 400 mm;
−
the safety distance is to be also doubled in case when the grade of reaction to fire is not proven.
