If the path of smoke exhaust such that it creates bad draft, that is, bad air flow (numerous curves, inappropriate 
smoke exhaust end, narrowing etc.), the smoke exhaustion can be bad i.e. in such cases the smoke exhaustion is 
not the best really.  
The smoke exhaust system from the stove functions on the basis of negative pressure and slight pressure from the 
smoke outlet pipe. It is very important that the smoke outlet system is hermetically closed (sealed). This required 
application of a smooth pipe from the internal side. First of all, it is necessary to analyze and study the plan and the 
structure of the room well enough at the moment when the smoke outlet pipe is installed through walls and the roof, 
in order to execute the installation of the pipe properly in accordance with the standards for fire protection.  
First it should be ensured that there is enough air for combustion in the room where the stove is located. It is 
recommendable to perform temporary inspection in order t ensure that the air for combustion comes properly to the 
chamber for combustion of biofuel. The stove functions on 230 V – 50 Hz. Pay attention not to tangle the power 
cable under the stove, to keep the cable far from warm spots and not to touch any sharp edge that could cut it. If the 
stove is electrically overloaded, this may lead to reduction of the lifetime of the electronic components of the stove. 

Never switch off the power supply by pulling out the switch while there is flame in the stove. This may 
threaten the proper functioning of the stove. 

 

 
3.2 SMOKE EXHAUST SYSTEM 

The smoke exhaust must be executed in accordance with the existing standards. The exhaust pipe should be well 
sealed. Look figures 1 to 7. 
Classical wall flues may be used for the smoke outlet and also flues can be made of pipes which must be well 
insulated (double wall) and sealed to avoid creating of condensation inside them.  
The exhaust pipe absolutely must not be connected to the remaining systems of any type, such as systems where 
the smoke is exhausted from the combustion chamber, the exhaust rail or the air distribution system etc. Also the 
flue exhaust must not be placed in closed or semi-closed rooms such as garages, tight corridors, under closed 
barracks or in any other place where smoke could appear. Once the stove is connected to the smoke exhaust 
pipeline, it is necessary to bring a professional chimney sweep to check and make sure that the flue doesn’t have 
any small holes or cracks. If such cracks do exist in the flue exhaust, in such case the smoke exhaust pipe must be 
coated with new material for the purpose of proper functioning.  
For this purpose, one may use rough pipes made of colored steel (with a thickness of minimally 1,5mm) or from 
stainless steel (with a thickness of minimally 0,5mm).     
The smoke (flue) exhaust system from metal pipes must have grounding in accordance with the existing standards 
and legal regulations. 

The grounding is demanded by law. 

This grounding connection must be independent from the stove grounding. 

The smoke exhaust pipe must be made according to the standards in terms of dimensions and materials which are 
sued for its construction (figure 1).  

A) Flue top resistant to wind  
B) Maximal cross section 15 x 15 cm or a diameter of 15 cm, maximal height of 4-5 m.  
C) Seal  
D) Inspection – control opening  

Flue pipes that are in bad condition or that have been made of inappropriate material (asbestos cement, zinc coated 
sheet metal etc.) with rough or porous surface are illegal and they endanger the proper operation of the stove. The 
smoke can be exhausted through a classical flue pipe (see the following figures) provided that the following 
regulations are fulfilled:  
- check the condition of maintenance of the smoke exhaust pipe or flue. If the smoke exhaust pipe is old, it should 
be replaced with a new one. If the flue has been damaged, it is good to repair the same or to renew it by inserting 
one steel pipe which is properly insulated with glass wool.
