2 Boiler Uses and Advantages
Condensing boiler VIADRUS CLAUDUS K 2 is intended for combustion of low pressure natural gas. The size of the
condensing boiler is suitable for heating of houses, recreation facilities and also for reconstruction of heat sources
in individual flats.
Heat output of the condensing boiler is 3.8 to 24 kW (K 2 L3X) and 7.8 to 48.1 kW (K 2 L5X).
The boiler body consists of castings made from special aluminium alloy. Individual sections are connected by
means of silicon rings and tightened by threaded bars. The maximum working overpressure of the boiler is 250 kPa
(2.5 bar). The body is tested by the test overpressure of 600 kPa (6 bar).
Combustion mixture is mixed in a mixer in a predetermined ratio of air - gas in its control range.
Water volume of the three-section boiler body is 9 l and the water volume of the five-section body is 13 l.
The efficiency of the boiler body at a temperature gradient of 50/30 °C ranges from 102 to 108% depending on the
desired performance.
Boiler advantages:
•
Low gas consumption.
•

4 Boiler description
4.1 Boiler construction
The heat exchanger of the condensing boiler consists of a front, middle (the number depends on the size of the
boiler) and the rear section. These castings are connected by means of silicon rings and tightened by threaded
bars. This boiler is equipped with a premixing burner. Combustion mixture is mixed in a mixer in a predetermined
ratio of air - gas at the whole performance range. Air is supplied to the mixer using the modulation ventilator. The
boiler is constructed for heating with preferred heating of HW. To heat HW, the manufacturer recommends
combination with the water heater.
Further, the boiler is equipped with LMS automatics and a gas valve. LMS automatic is an electronic control and
ignition automatics designed for gas central heating boilers with the modulated ventilator and pre-mixing burner. if
the boiler is to be controlled equithermally, it is necessary to connect the outdoor sensor. In this case, we
recommend using one of the communication devices, see chap. 6.3.
To increase the number of heating circuits, expansion module can be used according to project documentation.
Combustion air can be fed and flue gas can be exhausted to the chimney or through the wall.
The boiler is an appliance of B or C version.

5 Storage heater VIADRUS OV - H 100
Water heater VIADRUS OV – H 100 is a pressure device adapted to operate at a maximum water pressure of 0.6
MPa (6 bar). Hot service water heater is a device designed for heating and storing hot water.
The main part of the heater is a vessel made of steel sheet coated with a layer of enamel. The heater is equipped
with a heating coil with large heat exchange surface, which ensures fast heating of large quantities of water. All
connections are located in the upper part of the heater and are terminated with an external thread. The heater also
offers the possibility of connecting a circulation pump for circulating hot water, and s temperature sensor. There is
an outlet at the bottom part of the heater through which the vessel can be drained. The heater is equipped with an
additional anticorrosive device in the form of a magnesium anode whose function is based on the utilization of the
electrochemical potential difference between the anode and the tank. The magnesium anode is placed in the upper
part in the plug 2”. Thermal insulation of the heater is made of polyurethane foam free from freon, which minimizes
heat loss. An electric heater can be installed in the heater.
