On view of safety

 

 when installing the  boilers it is necessary to keep a safe  200 mm distance from combustible 

materials.  For easily flammable materials which burn quickly and by themselves also after the ignition source 
removal ( like paper, millboard, stiff paper, asphalt and tar boards, wood and fibreboards, plastics, flooring 
materials) the safe distance is doubled. The safe distance is to be doubled also in case that the combustibility 
degree of a building material wasn’t proved.

(extract from  

Č

SN 73 0823 : 1984) 

 

 

A – incombustible 

Granite, sandstone, concretes, bricks, ceramic tiles, mortars fireproof plasters,… …... 

B – hardly combustible  

acumin, izumin, heraklit, lignos, boards and basalt felt , fibreglass boards ,….. 

C

1

 – combustible with 

difficulties 

Beech and oak wood,  hobrex boards, plywood, werzalit, umakart,  sirkolit,…. 

C

2

 – medium combustible   Pinewood, larch, whitewood, chipboard and cork boards, rubber flooring  …... 

C

3

 – easily combustible  

Asphalt board, fibreboards, cellulose materials,  polyurethane, polystyrene, polyethylene, PVC, 
…. 

 

 

In case that it  has occurred the danger of combustible vapours or gases development and their penetration into 
the boiler room or at works with temporarily developed fire or explosion danger (flooring gluing works, painting 
works using the flammable paints, etc.), boiler must be shut down long enough before the works start by pulling 
the supply cord out of the socket or switching off the main switch of the burner.   

  
Warning: 
Don’t put any objects made of flammable materials on boiler and  within a distance smaller than the safe 
distance  from the boiler. 

 
 

 

5. Assembly procedure  

 

The assembly procedure is described in  „ VIADRUS G 700 boiler assembly manual “. 

 
 
 

6.Commisioning  

 

 The boiler commissioning, heat output setting and any interference with boiler electric part or 
connection of additional control elements can only be done by a contractual service  organization 
authorized to do the service works and a firm authorized to service the burner being operated. 

 

1.

 

Installation and assembly of the burner, its adjustment and boiler putting into operation together with burner 
must be done by  burner supplier ´s the service firm. This service firm will give a training to the user 
regarding the operation, provide him with burner operation manual and will ensure the  guarantee and after-
guarantee repairs.  

2.

 

Make a registration in Revision book before the boiler commissioning.
