3. Installation and
preheating of the sauna
heater
3.1 Preheating
Before use and arranging the stones, the sauna heater
must be heated to remove the protective agents. Any pro-
tective films and stickers must have been removed before.
Preheating shall be carried out on a non-combustible
surface and outside,
since paint emits harmful solvents
and smoke during heating. Use of a connection pipe in-
cluded in the delivery of the sauna heater in the upper joint
improves draft during preheating. 1-2 fireboxes of wood
are sufficient for preheating. After preheating and before
arranging the stones loose cover material should be re-
moved from the stone compartment of the sauna heater
with a steel brush. In case the external surface of the sauna
heater is painted, it should not be rubbed or wiped before
the first heating. The paint of the sauna heater will achieve
sufficient strength only after the first heating. Do not create
steam during the first heating.
3.2 Regulation of the height
The legs of the sauna heater are adjustable and can be
used for levelling the sauna heater and for adjusting the
height. There must be an air gap of at least 25 mm between
the sauna heater and the floor. Use a spirit level to check if
the sauna heater is level.
3.3 Connection with the stack
The sauna heater can be connected to the smoke flue from
the top or back of the sauna heater. Seal the unused open-
ing with the supplied cover. The sauna heater comes with
a short smoke flue connection pipe, which can be used to
connect the sauna heater’s smoke flue from the back. If the
connection with the smoke flue is done from the above, a
Kota connective flue or Kota smoke flue must be used. In
case of connection from the above, a Kota smoke flue tank
for heating water or a Kota stone basket can be installed
around the connective flue.
Do not push the connective flue too deep in the smoke flue,
because this would hinder the draft. Any leaks in the con-
nective flue also reduce the draft; therefore the connections
must be sealed with fireproof sealing material.
Leakage in
the connective flue causes combustion gases formed
in the sauna heater to ignite in the flue.
The connection
joint of the flue and the sauna heater must be 25 mm. The
diameter of the connective flue of the sauna heater and the
height from the floor are shown in clause
1.1.
Please take into account the clearance distance of the
modular smoke flue, see the manufacturer’s instructions.
3.4 Changing of the opening direction of the
firebox door
Figure 4
. Open the door and raise the hinge pin up (1)
so it comes out of the bottom hinge barrel. Hold onto
the door securely and turn the bottom part of the pin
and turn the bottom end of the pin up enough (2) so you
can pull the pin down (3) and the pin and door come
apart.
Figure 5
. On the side of the door with the handle, undo
the fastening screw of the handle so the handle comes
loose. Turn the handle around and reattach the locking
screw.
Figure 6
. On the inside edge of the door opening, undo the
limiter screw on the hinge side (1). Release the locking pin
(2) on the outer edge of the firebox door on the handle side
(2) with the help of an 8 mm open-end wrench. Remember
the correct sequence of the parts. Attach the locking pin
to the opposite side of the door opening and tighten it with
the open-end wrench. Do not tighten the screw so much
that the bushing of the locking pin locks. Attach the limiter
screw to the opposite inner side of the door opening.
Figure 7
. Position the door so that the hinge holes coincide
with the hinge pins. Position the hinge pin so that the lock-
ing tab comes down and push the hinge pin through the
upper hinge hole (1). Push the hinge pin through the hinge
holes in the bottom edge (2) and let it down into place (3)
on top of the locking tab. Carefully open the door. If the
door hits the housing of the sauna heater when it opens,
tighten the limiter screw. You can adjust the opening angle
of the door with the limiter screw. Make sure that the lock-
ing pin of the handle is working properly and if necessary
adjust it with an open-end wrench.
