VOLUME CALCULATION
For correct dimensioning of the stove, the sauna room volume in cubic metres must be
calculated (floor area x height). If the sauna is built of massive logs, multiply the volume by 1.5.
To the figure thus obtained, one cubic metre must be added per each non-insulated wall surface or
window square metre. Non-insulated wall surfaces include, for example, firewall, brick, glass brick.
If the stove is provided with a lateral water tank, add three more cubic metres.
Example: a sauna measuring 2 m x 3 m x 2.5 m = 15 m³. There is a firewall (5 m
2
) and a window
(1 m
2
), and the stove will be equipped with a lateral water tank. The volume is calculated as
follows: 15 + 5 + 1 + 3 = 24 m³. This figure is to be compared to the sauna sizes specified for
the stoves.
1.3
SAUNA VENTILATION
Properly arranged ventilation ensures the most pleasant sauna experience. The recommended
solution is directing of the supply air to the bottom part by an approx. 10 cm conduit, which should
be equipped with an adjustment device. Supply air valves and grilles must be positioned so that
they would not be prone to blockages. In addition to the air required for combustion, the stove
draws air to the space between the inner part and the outer mantle, from where the heated air is
discharged in a controlled manner to the sauna over the top moulding grille and the stones. All
Misa stoves have controlled air circulation that simultaneously heats up the stove stones and
sauna air to the correct temperature. In connection with this, fresh air is circulated through the
stove and directed to the upper part of the sauna, forcing used air out through the fire chamber and
smoke chimney. Adjustable ventilation valves installed to the ceiling level or into the ceiling are
used only for sauna drying and ventilation. They must be kept closed while using the sauna. When
using the product 15125R (Misa smoke chimney), this valve is not required, since the Misa
chimney is also equipped with AIR CHIMNEY!
If the sauna has mechanical ventilation, make sure there is no underpressure in the sauna during
heating. Exhaust air fans in the same room or on the same premises as the hearth can cause
problems.
1.4
SMOKE CHIMNEY
The sauna stove can safely be installed into T600 temperature rated smoke chimneys, unless
otherwise specified. In case of all our sauna stoves, the internal diameter of the smoke chimney
fire pipe must be at least 105 mm. The recommended smoke chimney draft is approx. -12 Pa. Do
not attach the heater to a divided smoke duct system.
The connection pipes to the chimney must comply with the same specifications.
To ensure fire safety and functionality, consider the dedicated guidelines regarding the
installation, safety distances, lead-throughs, etc. of the smoke chimney and pipes.
Follow the smoke chimney maintenance instructions to ensure functionality and safety.
