Positioning and installation

4.1

Regulations and directives

A solid fuel boiler may be only installed by a company with a valid authorization to perform its installation and maintenance. A project according
to the valid regulations must be prepared for installation. Before installation of the boiler in an old heating system, installation companies have to
perform rinsing (cleaning-up) of the whole system. The heating system has to be filled up with water, which complies with requirements
of ČSN 07 7401, and mainly its hardness mustn't exceed the required parameters.

WARNING!!! The manufacturer doesn't recommend using of antifreeze mixtures.
In case of the use of non-freezing or anticorrosive additive into heating water, the manufacturer/supplier of the additive has to
guarantee harmlessness of the originated mixture. In case of damage of the boiler or its part as a result of action of the originated
mixture, the manufacturer is not responsible for the occurred damages, and this damage cannot be solved within the warranty.
In case of triggering the two-way safety device, when water which does not comply with requirements of ČSN 077401 can be refilled, it
is necessary to prepare water in the system so that it met the requirements of this standard.

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. Each
solid fuel boiler requires a certain quantity of air for combustion. If it is not ensured by natural infiltration of the facility, it is necessary
to ensure it through a hole from the outdoor environment with a cross section of at least 100 cm
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.
