SAUNA WOODBURNING STOVE INSTALLATION

All of our sauna woodburning stove models are 
fitted with a flue pipe connection both behind and 
on top of the sauna woodburning stove. Block 
the unused opening with the cover plate included 
in the delivery. Also included in the delivery is 
a 160 mm flue pipe connector for connection 
of the sauna woodburning stove to a rear flue 
pipe. When connecting the sauna woodburning 
stove to the flue from the top of the woodburning 
stove, always use NARVI chimney pipes or NARVI 
chimney flues. 

Do not install the flue adapter pipe too deeply into the chimney flue, as this will 
reduce the flue draw. The gap between the flue adapter pipe and the chimney flue 
must be insulated e.g. with mineral wool. 

In connection with the sauna woodburning stove installation, ensure that the 
woodburning stove stands firmly on its base and that all of the safety distances 
mentioned in these instructions have been observed correctly.

We recommend the use of mineral wool quilt for insulation of the brick wall and 
tunnel section, as this material allows for thermal expansion. The tunnel model 
is connected to the flue from the top of the sauna woodburning stove. Always 
use NARVI chimney pipes or NARVI chimney flues. In connection with the sauna 
woodburning stove installation, ensure that the woodburning stove stands firmly on 
its base and that all of the safety distances mentioned in these instructions have been 
observed correctly.
