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.
