Boiler usage and advantages 

 

Cast-iron  sectional  gas  boiler  VIADRUS  G  90  is  equipped  with  law-emission  atmospheric  burner  and  is 
intended for burning  pf low-pressure natural gas. The boiler  is made in  B

11BS

design  it means it  is equipped 

with combustion gases reflux fuse.

 

It is suitable first of all for heating the middle–sized and bigger premises. 

The use of gas valves with an automatic control and watch of the gas cap tightness at the burner makes it 
possible  to  install  the  boilers  in  the  boiler  rooms  of categories  I  and  II.  The  boiler  is  only  made  as  the  hot-
water boiler with a forced circulation and work overpressure up to 400 kPa (4 bar). Before the dispatch the 
boiler is tested for tightness by 800 kPa (8 bar) testing overpressure.  
 
Boiler advantages: 

1.  High service life of the cast-iron boiler drum. 

2.  Simple operation and maintenance. 

3.  Reliable security and control elements  

4.  Gas combustion efficiency 92 %. 

5.  As a standard equipped with combustion gases reflux fuse. 

6.  Silent running and law electricity consumption. 

7.  Gas connected either from the left-hand side or from the right-hand side. 

8.  Connection  of  the  output  and  return  water  either  from  the  left-hand  side  or  from  the  right-hand  side  (it 

doesn’t apply to the 8-sectional version). 

9.  Possibility to connect the boiler in an cascade. 

10.  Possibility to equip with an equitherm regulation. 

11.  Two-stage burner (nominal/ reduced output). 

12.  Possible delivery in a decomposed state. 

 
The content of harmful substances in the combustion gases is significantly lower than the values prescribed 
by  the  guideline  MŽP  05  –  98  „Environmentally  friendly  product  “  and  meets  the  requirements  of  the  most 
strict European standards.
