Possibilities of placement
Boiler placement in dwelling premises (including corridors) is prohibited!
It is necessary to ensure permanent supply of air for combustion and ventilation to the room where the boiler will be installed.
Upon installation and usage of the boiler, it is necessary to observe all requirements of
ČSN 06 1008.
The boiler in the central heating system has to be connected to a separate venting unit. The chimney with a correct draught is the
basic assumption for a good function of the boiler. It influences both boiler power and its efficiency. It is nut suitable to use flue gas
elbows. The flue gas ducting from the boiler to the venting unit must be as short as possible, preferably without elbows with a slope
from the boiler upwards. The chimney has to have a prescribed draught (depending on the boiler size - see manual). It must be well
tightened and insulated to avoid condensation of water steam and tar.

Boiler positioning with regard of fire-fighting regulations:
While installing a boiler with a size of 5, 6 and 7 sections, we recommend that you to use original cast-iron pedestal (see Fig. No. 10) supplied
by the manufacturer. In case of placement of the boiler without a pedestal, it is necessary to observe conditions specified in Art. 1.

Fig. №. 11 Cast-iron pedestal of the
boiler
1. Positioning on the floor made of non-flammable material (Fig. No. 10):
place the boiler on the non-flammable pad exceeding the boiler layout on all sides by 20 mm and just on the depth of the boiler drum;
If the boiler is installed in a cellar we recommend installing it on a bedding at least 50 mm high.
the boiler has to be placed in the center of the pedestal.
2. Safety distance from flammable materials:
when installing and operating the boiler, it is necessary to keep a safety distance of 200 mm from the
materials of combustibility grade of 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.
