INSTALLATION
1.1
SAUNA STOVE SPECIFICATIONS
The wood-burning sauna stoves by Misa are CE marked. In order to qualify, the stoves have
passed a series of nominal heat output and temperature safety tests.
1.1.1 Nominal heat output, efficiency, emissions, flue gas average
temperature
For nominal heat output testing, the stove is installed to a sauna of the
maximum volume established for the sauna stove model. In addition to this, the test sauna is
equipped with powerful ventilation: the air is fully replaced six times per hour. Smoke chimney
draft: 12 Pa. A sufficient amount of firewood is used to heat the sauna up to the temperature of
90 °C. During the test, flue gas temperature and emissions are measured and the stove
efficiency calculated. Firewood used for the test: birch.

Safety distances
For temperature safety testing, the stove is installed into a sauna of the smallest indicated size.
The stove is heated so that the sauna temperature stabilises at 60 °C. After this, the flue draft is
increased 3 Pa, the stove draft adjuster is fully opened and the fire chamber is filled (up to the
hatch upper edge) with dry birch. The sauna temperature must rise at least to 110 °C. The
temperatures of combustible structures are measured at predetermined safety distances. During
the test, the instantaneous peak temperature of flue gas is also measured.
The floor under the stove must be of non-combustible material (min. 6 cm thick concrete slab) or
protected by bottom plinth suitable for the stove used. In addition to this, combustible floor in front
of the firewood hatch must be protected by spark plate.
Note! If the sauna stove is installed onto floor with water insulation, a bottom plinth must also be used.
