The exact size of the chimney is determined by STN 73 42 10. The prescribed draft of the chimney is
given in the Technical parameters. If your chimney does not reach the prescribed chimney parameters,
it is possible to install an additional MAX FAN 160 fan behind the boiler, which can create the required
chimney parameters. When choosing the type of chimney or boiler operation, keep in mind that the
stainless steel insulated chimney (usually led externally along the building envelope) has the best
properties in terms of the onset of the chimney draft after heating, because it heats up quickly along its
entire length. A chimney lined with a stainless steel insert has worse properties in terms of the onset of
the chimney draft, because it heats up more slowly than an insulated chimney. An unloaded chimney
(for example, brick or ceramic) has the worst properties in terms of the onset of the chimney draft,
because its accumulation to the operating temperature takes longer. Therefore, if heating or boiler
start-up is problematic, consider the reconstruction of the chimney and its equipment with a stainless
steel insert

4.6 METHOD OF CONNECTION OF CONTROLS AND SAFETY ELEMENTS
The boiler is supplied with basic equipment with regulating and control elements. These must be
supplemented by elements that are not part of the boiler delivery, but must be installed in the
heating circuit. These are, in particular, a safety valve against exceeding the permissible pressure
in the heating system (we prescribe 2.5 bar), a valve for the after-cooling loop of the boiler for
the removal of excess heat from the boiler to the waste and a vent valve for the correct operation
of the boiler. The expansion tank in the system must have a sufficient volume, which is
determined by the designer of the heating system according to the valid regulations. The
electrical installation associated with the boiler's additional equipment must be carried out by a
specialist in accordance with the applicable standards.
WARNING!
The heating system must be equipped with a safety valve against exceeding the
pressure in the boiler (2.5 bar). If the safety valve does not work, the excess pressure will have
nowhere to escape and the boiler may explode!
BOILER PROTECTION AGAINST OVERHEATING
Each wood gasification boiler must be equipped
with a functional cooling circuit. The correct valve to provide this function can be ordered as an
accessory.
WARNING!
The cooling circuit against overheating of the boiler must not be used according to
EN 303-5 for purposes other than protection of the boiler against overheating. The valve on the
cooling water supply to the boiler cooling circuit must be permanently open and the boiler cooling
circuit must be connected to a functional cooling water distribution (eg cold water distribution)
at a temperature of 10 to 20 °C and a working overpressure of 2 - 6 bar ensuring safe operation
even in the event of a power failure.
Recommended installation schema
The connection system consists in heating the water in the storage tank, from where the
accumulated heat is gradually taken according to the requirements of the heated space.
