Boiler description

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.
