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.
NB! If the sauna heater is equipped with a water tank
please check before preheating that the water tank faucet
and safety plug are installed and that
the tank is filled
with clean water.
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 Installation of a door and changing of the
opening direction of the door
Figure 7.
Open the door and raise the hinge pin up 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) that you can pull the
pin down (3) and the pin and door come apart. For instal-
lation proceed in reverse order. First push the upper edge
of the door in its place and thereafter push the pin through
the upper eyelet. Thereafter turn the door and pin in their
places from below and let the pin into the bottom eyelet.
The pin is correctly installed when the wider areas of the
pin are facing down. In this case the pin cannot move away
from its place. Door installation is easier when you use long
flatnose pliers.
3.5 Installation of the faucet, models with a
water tank
The water tank is on the side of the stove and it has a large
opening for filling it. For the water volume, see clause
1.1.
The faucet is installed when the sauna heater is installed.

Place the faucet so that the threads are visible on
the inside of the tank. Place the faucet so that the threads
are visible on the inside of the tank. Place the washer on
