Description 

4.1 

Boiler construction  

 

The main part of the cast iron boiler is the cast iron sectional boiler drum made of grey cast iron according to 
EN 1561: 

-

 

quality 150 (previously 

Č

SN 42 2415) or 

-

 

quality 200 (previously 

Č

SN 42 2420). 

 

The pressure parts of the boiler correspond to the strength requirements according to: 
EN 297  

Gas  –  fired  central  heating  boilers  –  Type  B

11

  and  B

11BS 

fitted  with  atmospheric  burners  of 

nominal heat input not exeeding 70 kW 

EN 303-1  

Heating boilers – Part 1: Heating boilers with forced draught burners – Terminology, general 
requirements, testing and marking 

EN 303-2  

Heating boilers – Part 2: Heating boilers with forced draught burners – Special requirements 
for boilers with atomizing oil burners 

 

VIADRUS  G  50  boiler  has  a  cast-iron  closed  overpressure  combustion  chamber.  This is a boiler with three 
draughts. 
The  boiler  output  is  determined  by  number  of  sections.  Individual  sections  are  interconnected  by  means  of 
forced-on  insertions  and  tightened  with  the  anchor  bolts,  thus  creating  a  combustion space with convection 
surface  and  the  boiler  water  volume  inside  the  sections.  Heating  water  input  and  output  are  situated  in  the 
rear part of boiler.  
To  the  basic  boiler  accessories  belong  the  sectional  boiler  drum  assembled  together  with  insulated  burner 
door, smoke extension, sheathing incl. thermal insulation and boiler control panel. Optionally other pieces of 
accessories are available.  
Insulated boiler door and the smoke extension are sealed by means of packing cord.
