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. The sauna woodburning stove comes fitted
with adjustable feet to assist accurate installation.
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.
Installation of tunnel model sauna woodburning
stoves:
The wall separating the fire tending room and
the sauna woodburning stove must be built of
fire-resistant material such as brick.
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.
Measurement A is applied to wooden
surfaces in accordance with the thermal
protection method applied:
- no thermal protection 500 mm
- single-layer, light thermal protection 250 mm
- double, light thermal protection 125mm
