Regulations and guidelines
The solid fuel boiler can only be installed by a firm holding a valid licence to carry out its installation and
maintenance. A project according to the valid regulations must be elaborated for installation. Before the
boiler installation on an older heating system the installation firm must flush out(clean) the whole system.The
heating system must be filled with water meeting the
Č
SN 07 7401 requirements; especially its
hardness must not exceed the required parameters

WARNING!!! The use of anti-freeze mixture is not recommended by the manufacturer.
In case of two way safety vent reaction, when there is a possibility of boiler having been filled with
the water, which does not meet the
Č
SN 077401 requirements it is necessary to change the water in
the heating system so that it meets the
Č
SN 077401 requirements again.

Positioning possibilities
Boiler positioning in the living space (including corridors) is prohibited!
The installation of the boiler must comply with all requirements of
Č
SN 06 1008.
The boiler positioning with regard to the fire regulations:
1.
Installation on a floor made of incombustible material (Fig. No. 9)
−
The boiler can be installed on a fireproof floor exceeding the boiler platform by 20 mm on the sides
and only up to the boiler drum depth.
−
If the boiler is positioned in a cellar we recommend to install it on a retaining wall (substruction)
minimum 50 mm high
−
install the boiler in the middle of the retaining wall
2. A safe distance from the combustible materials:
−
when installing and operating the boiler it is necessary to keep a safety 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 wood-fiber boards, plastics, floor coverings) the safe distance has to be doubled, i.e. to
400 mm;
−
safe distance should be doubled as bulb where the grade of reaction to fire has not been proved.
