Regulating and security elements 

The smoky flap of the smoky chimney – pot regulates the climb of the product of consumption from the boiler to the chimney. It is regulated with 
the handle with a rod in the upper left part of the boiler next to the stoker hole. 
Stifling  of  the  ash  door  regulates  the  inflow  of  the  combustion  air  under  the  grate  of  the  boiler.  It  is  regulated  by  the  draught  governor  or 
manually with an adjusting screw of the stifling.  
The air rose of the stoker door serves for carrying the secondary air to the burning space. To control the rose it is necessary with respect to the 
higher surface temperature of the stoker door to use an instrument that is part of the delivered tools.  
The cleaning cover of the smoky chimney – pot located in its bottom part serves for cleaning the embedded waste product caused by burning. 
There are barriers of the smoky channel between the front and medium sections above the stoker hole of the boiler VIADRUS U 22 C. It serves 
for  reducing  the  draw  –  away  cross  -  section  and  for  a  better  utilization  of  the  product  of  consumption  at  the  boilers  of  smaller  power  (2  –  5 
sectional). They are used with a various cross – section width according to the sizes of the boilers in conformity with this tab.:

A thermomanometer in the control box serves as an associated device for measuring the temperature of the heat water and water pressure in 
the heat system. The sump of the thermomanometer sensor is located in the upper part of the back boiler section.

Regulations and instructions 

The  boiler  for  solid  fuels  can  be  installed  by  a  company  with  a  valid  authorization  to  perform  its  installation  and  maintenance.  For 
installation a project in accordance with valid regulations must be executed.  
The heating system must be filled with water, that meets the 

Č

SN 07 7401 requirements, especially its harness must not exceed the

Placing possibilities 

Boiler positioning in the living space (including corridors) is prohibited! 
A continuous air supply for burning and eventual ventilation must be ensured for the room where the boiler is installed.  
The installation of the boiler must comply with all requirements of 

Č

SN 06 1008. 

Boiler placing with regard to fire regulations: 

1. 

Placing on floor of flame resistant material (Pic.4) 

-

 

boiler to be put on a flame resistant backing exceeding the boiler platform over 20 mm at sides and only on the boiler drum depth. 

-

 

if the boiler is situated in a cellar we recommend to place it on a bedding of minimum 50 mm height. 

2. 

Safety distance from the flammable materials 

-

 

when installing and operating the boiler it is necessary to keep a safety distance of 200 mm from the materials of combustibility grade 
A1, A2, B and C (D);  

-

 

for easily combustible materials of combustibility grade E (F), which quickly burn and burn themselves even after removal of ignition 
source (such as paper, cardboard, asphalt and tar paper, wood and wood-fiber boards, plastics, floor coverings) the safe distance has 
to be doubled, i.e. to 400 mm;  

-

 

safe distance should be doubled as bulb where the grade of reaction to fire has not been proved.
