Installation of a tunnel sauna heater.
For sealing brickwork and tunnel part we recommend the
use of a mineral wool slab, which provides moving space
required for thermal expansion. A tunnel model is connect-
ed to the stack from the top of the sauna heater.
In connection with the sauna heater installation, ensure
that the heater stands firmly on its base and that all of the
safety clearances mentioned in these instructions have
been observed correctly.
PROTECTION OF THE FLOOR IN FRONT OF THE SAUNA HEATER
Floors made of inflammable material must be protected
with a metal plate that reaches at least 100 mm to both
sides of the sauna heater and 400 mm in front.
3.7 Air flow direction adjusting plates of
the sauna heater

AIR FLOW DIRECTION ADJUSTING PLATES
The position and condition of the plates must be regularly
inspected. A sauna heater must not be used without air
flow adjusting plates.
3.5 Sauna heater stones
We recommend that you use Kota olive dolerite stones.
Natural stones are not suitable to be used as sauna heater
stones 10–15 cm. Before using the stones, they must be
washed to eliminate any impurities.
Bigger stones are
placed in the bottom of the stone compartment and
the rest are piled sparsely so that air can move freely
between the stones. Flat stones shall be stacked in
upright position.
The stones must not block air openings
and stones must not be stacked over the top surface of the
sauna heater.
The recommended quantity of stones in
the sauna heater is shown in clause 1.1.
The use of stones
with a regular shape (rectangular, etc.) and light or ceramic
stones is forbidden because of a risk of too tight stacking.
3.6 Installation of a tunnel sauna heater
A wall between the heating room and sauna heater must
be made of non-combustible material, for example bricks.
