Connecting the sauna stove with the chimney flue 

• The sauna stove must be connected to the chimney by a specialist 
• Flue gas outlet is on the top of the sauna stove. The sauna stove is connected to the chimney flue with special flue pipes that may be caulked with heat-resistant sealing rope, when necessary 
• Curves of the elbows of the connection pipes must be smooth to minimize draught loss.  
• The pipe is inserted though the wall of the chimney and then sealed with mineral wool.  
• The flue gases of the stove must be directed into a separate flue. It is forbidden to use a common flue that is utilised with other furnaces.  

*As specified by HUUM, utilisation of forced extract ventilation might cause problems with air exchange of the room and insufficiency of furnace combustion air; therefore, designing and constructing such ventilation systems is permitted only on the sole responsibility of a licensed specialist.
